Best casino games online in Ireland, ranked by the odds

Best casino games online: the short answer

If you want the best casino games online, start with the numbers that decide how long your money lasts: the house edge on table games and the RTP (return to player) on slots and instant games. Both measure the same thing from opposite ends. A game that returns 97.30% keeps 2.70% of everything staked over the long run; a slot with a 96.50% RTP keeps 3.50%. Neither figure tells you what happens in the next ten minutes, but across hundreds of bets it is the single best guide to value.

On that measure the order is clear. The Banker bet in baccarat carries a 1.06% house edge with eight decks, and the Player bet 1.24%. European roulette sits at 2.70%, roughly half the 5.26% of the American double-zero wheel. Blackjack, played with basic strategy at a table that pays 3 to 2, is widely rated among the lowest-edge games in the casino, though its exact edge depends on the table rules; a 6 to 5 table costs you roughly 1.39% more. Among slots, the provider figures put Big Bass Bonanza at 96.71%, Gates of Olympus at 96.50% and Sweet Bonanza at 96.48%, and BGaming lists Plinko at 99%.

Value is not the only thing that matters, though. Some people want a slow, social evening at a live roulette table; others want fast rounds, big multipliers and a short session on the bus. So below we rank the games by the odds first, then sort them by what they are good for: beginners, small budgets, mobile play, live dealers and crash games. Each game links to its own guide on CasinoTill, and the later sections cover where to play from Ireland, with 22BET as our top pick.

One rule runs through the whole page. RTP figures come from the providers’ own pages, and a casino can run a different version of the same game. Before you play, open the game’s info or help screen and check the RTP shown there. If it is lower than the figure here, you are looking at another version, and the maths on this page no longer applies.

How we rank the best casino games

A list of top casino games is only as useful as the method behind it. We do not score games on graphics or on how loudly they are promoted. The heaviest factor is the return: the house edge or RTP, taken only from a provider’s official page or from standard table-game maths. Where a provider does not publish a figure we could confirm, we say so rather than guess, and those games are judged on rules and transparency instead.

After the return come the things that shape a real session: how volatile the game is, how clear the rules are, how much a beginner can get wrong, how it plays on a phone and how easy it is to find in the lobbies Irish players use. Fun counts too. A game with a fine RTP that bores you into raising your stakes is not good value in practice, and a game you enjoy at a modest stake can be.

One caveat before the tables. The edge is a long-run average. In a single evening anything can happen, and a high-volatility slot can pay many times its stake or nothing at all. The ranking tells you which games cost the least on average, not which game will pay tonight.

Top casino games ranked by house edge and RTP

Here is the core ranking of casino games with the best odds of winning, on figures we can stand behind. Return is the share of stakes a game pays back over time; the house edge is what is left. For table games we turned the house edge into a return so you can compare them directly with slots. The last column is the average cost of €100 in total bets — not €100 deposited, but €100 staked, which can happen in a few minutes on a fast game.

Two things stand out. First, the gap between the best and worst bets is large: the five-number bet on an American wheel costs more than seven times as much per euro as the Banker bet in baccarat. Second, the best slots and the best table bets are closer than many players think. A 96.71% slot costs about €3.29 per €100 staked, against €2.70 on European roulette. The difference is real, but it is smaller than the gap between the European and American wheels.

Games missing from the numbers are not necessarily poor. Spribe’s Aviator and Mines, InOut Games’ Chicken Road, Evolution’s Crazy Time, Book of Dead and Rainbow Riches all have RTP figures circulating on third-party sites, but we could not confirm them on the providers’ own pages, so we leave them out of the table. Each game’s info screen shows the RTP of the version a casino runs — read it before you stake.

What the house edge costs you: three worked examples

Percentages are abstract, so here is what they mean in euro. Say you bring €50 and bet €1 at a time on European roulette. Over an evening you might place 100 bets, which is €100 staked. The average cost is €2.70. Put the same €100 of action on the Banker bet in baccarat and the average cost is €1.06. Run it through American roulette and it climbs to €5.26 — about double the European wheel for exactly the same kind of game.

Slots work differently because they are fast. At €1 a spin, 300 spins is €300 staked even if your balance never rises above €50, because wins are fed straight back into new spins. On a 96.50% slot such as Gates of Olympus, €300 of spins costs €10.50 on average; on a 96.08% slot like Starburst it costs about €11.76. Pace matters as much as RTP: a game with a slightly better return played twice as fast can cost you more per hour.

The third example is the blackjack payout. At a 3 to 2 table a €10 blackjack pays €15; at a 6 to 5 table it pays €12. That €3 gap on one of the most common winning hands is why 6 to 5 tables cost roughly 1.39% more. Over €500 of hands, that is about €6.95 in extra expected cost — enough to turn a good game into an average one.

None of this predicts a single session. Variance can hand you a winning night on American roulette and a losing one at baccarat. But if you play regularly, the edge is the price you pay for the entertainment, and choosing a lower-edge game is the simplest way to make the same budget last longer.

Top 10 casino games: our list for Irish players

If you want one list to take away, here it is. These top 10 casino games balance the odds with how enjoyable and easy to follow each one is. Where we could confirm a figure it is included; where we could not, the game’s own section further down explains what to check instead.

Poker is missing on purpose. Online poker against other players is a game of skill with a rake rather than a house edge, so it cannot be ranked on the same scale. It has its own section below, alongside the best casino table games.

• Baccarat, Banker bet — 1.06% house edge with eight decks and no decisions to get wrong.
• Blackjack at a 3 to 2 table — among the lowest edges in the casino when you follow basic strategy.
• European roulette — 2.70% on every standard bet; the best wheel to choose.
• Plinko by BGaming — 99% RTP on the provider’s figures and a top multiplier of x1000.
• Big Bass Bonanza — 96.71% RTP and money symbols worth up to 2,000x.
• Gates of Olympus — 96.50% RTP, tumbling wins and multipliers up to 500x.
• Sweet Bonanza — 96.48% RTP and 2x–100x multipliers in the free spins.
• Starburst — 96.08% RTP and a 23.00% hit frequency for steady, low-drama play.
• Live game shows such as Crazy Time — big-studio entertainment; check the RTP in the help screen.
• Crash games such as Aviator — short rounds where you choose when to cash out; check the RTP in the game info.

Best casino table games and the best casino table game odds

Table games are where the best casino table game odds live, because their rules are fixed and the maths has been worked out for decades. Three of them — baccarat, blackjack and roulette — appear in almost every lobby, both as software (RNG) tables and as live dealer tables streamed from a studio. Poker is the odd one out: you play against other people rather than the house, so it has no house edge in the usual sense.

The table below sums up the best bet and the bet to skip in each game. The pattern is the same everywhere: the main bets carry the low edges, and the extras — side bets, exotic combinations, worse payout tables — are where the casino earns more. If you remember one rule from this page, make it this one: play the core bet at a table with standard rules.

Blackjack online: casino card games with the best odds when played well

Blackjack is the best game to play at a casino if you are willing to learn a little. Every hand asks you to decide — hit, stand, double or split — and those decisions move the house edge. Played on instinct, blackjack gives a lot away; played with basic strategy, a simple chart of the best move for every total against every dealer card, it becomes one of the casino card games with the best odds. The exact figure depends on the rules at that table: the number of decks, whether the dealer hits soft 17 and whether you can double after a split. That is why we do not quote one number for it.

The rule you can check in two seconds is the blackjack payout. The standard is 3 to 2, usually printed on the felt as “Blackjack pays 3 to 2”. Some tables pay 6 to 5 instead, which on a €20 bet means €24 rather than €30 for a natural. That one change makes the game about 1.39% worse for you — more than the entire house edge on the Banker bet in baccarat. Walk past those tables.

Side bets such as Perfect Pairs or 21+3 are fun, but they are separate wagers with their own, usually higher, edges, and basic strategy does nothing for them. Insurance is the classic beginner’s trap: it looks like protection when the dealer shows an ace, but basic strategy says to decline it.

Online you have two ways to play. RNG blackjack is quick, lets you set your own pace and suits practising strategy at small stakes. Live blackjack is slower, with a real dealer and seats shared with other players. Our blackjack online guide explains the rules and basic strategy step by step, and covers how to spot a 3 to 2 table in a busy lobby.

Baccarat online: the casino game with the best odds for beginners

If you are asking which casino game has the best odds of winning without needing any skill, baccarat is the answer on the published figures. You make one choice — Banker, Player or Tie — and the cards are dealt by fixed rules. Nobody at the table decides whether to draw a third card, so a beginner plays exactly as well as an expert. With eight decks, the Banker bet has a 1.06% house edge and the Player bet 1.24%.

The Banker bet wins slightly more often, which is why the casino takes a cut. A winning Banker bet pays 19 to 20, the same as even money less a 5% commission. Bet €20 on Banker and win, and your profit is €19 rather than €20. Even after that commission it is the lowest-edge main bet in the casino on the figures we use. Some tables change how the commission works, for example no-commission versions with reduced payouts on certain wins; their edges are not the ones quoted here, so read the payout table before you sit down.

The Tie bet pays more and tempts people after a run of ties, but its edge is far higher than either main bet, and the same goes for most side bets. Past results mean nothing either: a scoreboard full of Banker wins does not make Player “due”. For the table types, the scorecards and the bets worth skipping, see our baccarat online guide.

Baccarat suits a calm session with few decisions. Its weakness is that it can feel repetitive, and on a fast RNG table a lot of stakes go through in a short time, so keep an eye on how many hands you play as well as on the edge.

Roulette online: European wheel first, American wheel never

Roulette is the easiest of the top casino games to pick up: choose numbers, colours or groups, and wait for the ball. What decides the value is the wheel, not the bet. On a European wheel with one zero, the house edge is 1/37, or 2.70%, and that figure is the same whether you back red, a dozen or a single number. On an American wheel with a zero and a double zero it rises to 1/19, or 5.26%, and the five-number bet on 0, 00, 1, 2 and 3 costs 7.89%.

So the practical rule is short: look for a single zero on the wheel and on the betting layout before you place a chip. Lobbies often put both versions side by side. Over €200 of bets, the European wheel costs about €5.40 on average and the American one about €10.52 — nearly twice the price for the same game.

Because every standard bet on a European wheel carries the same edge, betting systems do not change the maths. Martingale, Fibonacci and the rest move money between frequent small wins and rare large losses; they cannot turn a 2.70% edge into a positive one. Pick the bet that suits the pace you like — outside bets for long, steady sessions, single numbers for fewer but bigger wins — and keep stakes in proportion to your budget.

Live roulette adds a real wheel and a croupier. Some live versions also add random multipliers on a few numbers each spin; those games change the payouts, so their edge is not the one quoted here. Our roulette online guide covers every bet and the main variants.

Poker online: a skill game with a rake, not a house edge

Poker sits apart from the rest of this list. In player-versus-player poker you compete against the other people at the table, and the site takes a small cut of each pot or a tournament fee, known as the rake. There is no fixed house edge to rank. Your long-run results depend on your decisions and on the strength of your opponents, so stronger players can come out ahead of weaker ones over time, while a new player usually pays for their education.

Casino versions are different. Games such as Casino Hold’em or Three Card Poker are played against the house with a fixed paytable, so they have a house edge like any other table game. We do not quote one here because it varies by version and paytable; check the rules screen before you play.

Poker is the right choice if you enjoy thinking, reading opponents and longer sessions, and a poor one if you want quick, low-effort rounds. Start at the lowest stakes, play fewer tables than you think you can handle, and treat the first months as practice. Our poker online guide covers the hands, the formats and the first steps.

Best online slots by RTP: Big Bass Bonanza, Gates of Olympus and more

Slots fill most of any lobby, and choosing between them comes down to two things: RTP and volatility. RTP is the long-run return; volatility is how that return arrives — small, frequent wins or long dry spells broken by big ones. The provider figures below are for the standard versions. A casino can run a lower-RTP version of the same title, so open the info screen before you spin. For a wider shortlist, see the best online slots in Ireland.

On the numbers we can confirm, Pragmatic Play’s Big Bass Bonanza is the best big bass game to start with and the highest-RTP slot on this page at 96.71%. Three, four or five scatters give 10, 15 or 20 free spins, money symbols are worth up to 2,000x, and every fourth wild collected retriggers the round with a bigger multiplier (2x, 3x, then 10x). Gates of Olympus (96.50%) and Sweet Bonanza (96.48%) both pay for eight or more matching symbols anywhere on screen and add multipliers — up to 500x in Gates, 2x to 100x in the Sweet Bonanza free spins.

Starburst is the opposite kind of game: NetEnt’s 2012 classic on five reels and three rows with 10 lines, a 96.08% RTP, a 23.00% hit frequency and a top payout of 800 times the bet. That modest cap is why it suits long, steady sessions. Book of Dead, released by Play’n GO on 14 January 2016, is built around its free spins: three scatters give 10 of them with an expanding symbol that can cover whole reels.

Fishin’ Frenzy from Blueprint Gaming has 10 lines and a 96.12% RTP in its base version, but Blueprint also lists 90%, 92%, 93% and 94% versions, so the info screen matters more here than anywhere. Rainbow Riches is a familiar name in many lobbies, but we found no official page with its figures, so check the RTP inside the game.

Best Megaways games and best online jackpot games

Megaways is a reel mechanic, not a single game. Big Time Gaming created it and licenses it to other studios, which is why Megaways versions of many popular titles exist. Instead of fixed lines, the number of symbols on each reel changes every spin, so the number of ways to win changes too. Two spins in a row can look completely different, and that variety is the appeal.

The best Megaways games are judged like any slot: the RTP on the info screen, how the free spins trigger and whether the volatility suits your budget. Megaways titles tend to swing harder than classic 10-line slots, so a smaller stake and a longer budget work better than chasing the feature at a high bet. Our Megaways slots guide explains the mechanic in detail.

Jackpot slots are a separate decision. With a progressive jackpot, part of every stake feeds the prize pool, and that share comes out of the return on ordinary spins. You trade a little everyday value for a small chance at a very large prize, which is a fair trade only if the jackpot is the reason you play. Before you choose among the best online jackpot games, compare the RTP on the info screen with a regular slot you like — the gap shows what the jackpot costs you per spin — and check the qualifying bet. Our jackpot slots guide covers how the prizes are paid.

Live dealer games and game shows: Crazy Time and the live tables

Live casino games stream a real dealer from a studio to your screen. For the classic tables the maths does not change: live European roulette carries the same 2.70% edge as the software version, and eight-deck live baccarat the same 1.06% on Banker. What changes is the pace. A live table deals far fewer rounds per hour than an RNG table, so the same budget usually lasts longer, and the dealer, the chat and the other players are a big part of the fun.

Game shows are a different product. Crazy Time from Evolution is a big money wheel with number segments, bonus games and extra multipliers. It is one of the most entertaining things in a live lobby, but it is built for spectacle rather than value, and we could not confirm its RTP on an official Evolution page, so it stays out of our odds ranking. The help screen inside the game shows the return for each bet; read it before you play.

Choose live games when you want a slower, more social session, and stick to the tables that keep the low edges: single-zero roulette, 3 to 2 blackjack and Banker or Player in baccarat. Our live casino guide explains how the studios, seats and bet limits work.

Best crash game casino picks: Aviator, Plinko, Mines and Chicken Road

Crash and instant games suit short sessions on a phone. Rounds last seconds, the rules fit on one screen, and usually you control one thing: when to stop. That speed is also the main risk. Fast rounds push a lot of stakes through in a few minutes, so even a good return costs more per hour than you expect.

Aviator by Spribe is the best-known crash game: a plane takes off, a multiplier climbs, and you cash out before it flies away. An automatic cash-out, where the game offers one, helps you stick to a plan. Plinko drops a ball through rows of pegs into multiplier slots; BGaming’s version, released on 28 January 2019, lists a 99% RTP and a top multiplier of x1000 — the highest return we can confirm for any game on this page. Mines hides mines among a grid of tiles and raises the payout with each safe tile you open, and Chicken Road from InOut Games uses the same idea with a chicken crossing lanes of traffic: each step raises the multiplier and the risk.

So which is the best Aviator game, or the best crash game overall? On value, BGaming’s Plinko has the only official figure we found. Aviator, Mines and Chicken Road have RTP figures circulating on third-party sites but not on official pages we could read, so check each game’s info screen. In most of these games the cash-out point or risk setting changes how bumpy the ride is rather than the long-run return. Many crash games are also “provably fair”, which lets you check each round after it is played — useful for trust, but it does not change the odds.

Slots vs table games vs live dealer vs crash games

Good online casino games come in four families, and each trades value, pace and fun differently. The right one depends on how you like to play rather than on a single figure. Someone with €30 and an hour may get more from a live roulette table, where the pace is slow, than from a fast slot. Someone who wants ten minutes of play on the Luas is better served by a slot or a short crash session at a fixed stake.

Mixing is fine. Plenty of players start the evening at a low-edge table and finish with a few spins on a favourite slot. The point is to know what each part of the session costs and to put most of your stakes where the edge is lowest.

• Table games (RNG) — the lowest edges: 1.06% to 2.70% on the best bets. Fast, with a little skill needed for blackjack. Best for players who want the best odds.
• Live dealer tables — the same edge as the software version of each game, at a much slower pace. Best for social, longer sessions.
• Live game shows — check the help screen for the return. Built for entertainment rather than value.
• Slots — about 3.3% to 3.9% on the titles we list, the most variety and the biggest multipliers. Very fast, no skill.
• Crash and instant games — from 1% on BGaming’s Plinko to unknown until you open the info screen. Very fast; best for short sessions on a phone.
• Poker against players — a rake instead of a house edge; the only family where skill decides long-run results.

Best casino games for beginners

If you are new, the best game to play in a casino is one where you cannot make an expensive mistake. That points to baccarat, where you pick Banker or Player and the rules do the rest, to European roulette, where every standard bet has the same 2.70% edge, and to simple slots with clear paytables such as Starburst. Blackjack is a good second step once you have learned basic strategy, and poker is best left until you know you enjoy it.

Crash games look simple, but their speed makes it easy to lose track of how much you have staked. If you try them, use a fixed stake and the auto cash-out, and decide on a number of rounds before you start.

A worked example: with €40 for the evening and €0.40 stakes, you have 100 bets of play. On European roulette that is €40 staked and an average cost of about €1.08. Play the same session at €2 a spin and the budget can be gone in 20 spins.

1. Pick one gameStart with baccarat, European roulette or a steady slot rather than hopping between ten titles.
2. Read the info screenCheck the RTP or the payout table and confirm the version: a single zero on the wheel, 3 to 2 on the blackjack felt, standard commission in baccarat.
3. Try the demoMany slots and instant games have a play-money demo. Ten minutes shows you the pace and features without spending anything.
4. Size your stake to your budgetDecide what the session may cost, then pick a stake that gives you at least 50 to 100 bets.
5. Set a limit before you playAdd a deposit limit in your account and stop when the session budget is spent rather than topping up.

Best online casino games to win money: what is realistic

People often ask what the best casino game to make money is. The honest answer is that no casino game is built to pay you over time: apart from poker against other players, every game on this page has a house edge, or an RTP below 100%. The best you can do is lose less on average while you play, which is exactly what choosing a low-edge game achieves. In that sense the casino games with the best payouts are the ones at the top of our ranking.

Within that, the best online casino games to win money in a single session are the ones where a modest win is likely, not the ones with the biggest headline prize. Even-money bets on a low-edge table — Banker or Player in baccarat, red or black on a European wheel — win small amounts often. A slot or crash game with a top prize of 1,000x or 2,000x mostly pays far less than that, and the big hit may not come in your session at all.

If you are looking for the best online casino games for real money, these habits do more for your results than any betting system. For the casino side of the same question — how payout percentages and withdrawal speed differ — see our guide to the best payout casino options.

• Play the lowest-edge version of the game you enjoy.
• Use a stake small enough to ride out a losing run.
• Set a win target as well as a loss limit, and stop at either.
• Withdraw wins instead of feeding them back through fast games.
• Ignore systems and predictor apps — they do not change the edge.

Best mobile casino games and the best free casino games

Almost every game on this page plays on a phone, but some suit a small screen better. The best mobile casino games have large buttons, short rounds and clear text: portrait-mode slots, crash games such as Aviator, Plinko and Mines, and RNG roulette or baccarat with a simplified layout. Live tables work well too, though the stream needs a steady connection and uses more data. Whether you are after the best iPhone casino games or the best Android ones, you are really choosing a casino’s app or mobile site, and the games come with it — including Aviator, which runs inside the casino rather than as a separate download. The best PC casino games are the same titles, with more room for the betting layout. Our mobile casino guide covers the set-up.

The best free casino games are the demo versions of the real ones. Many providers offer play-money modes for slots and instant games, which is the best way to learn features and pace; just remember the balance is not real, so it tells you nothing about what you would win. Our free slots page explains how demos work.

Two other kinds of “free” are different. Free spins are a casino bonus: real-money spins on a chosen slot, usually with wagering rules attached, so read which slot, what each spin is worth and how winnings are wagered. Social casino apps that hand out free coins with no deposit are entertainment only — the coins have no cash value and cannot be withdrawn, so the best social casino games are simply the ones you enjoy playing.

Best casino games by budget and session length

The best game for €10 on a phone is not the best game for €100 across an evening. Two numbers decide the fit: how many bets your budget buys at your chosen stake, and how many rounds the game deals per hour. A slow live table stretches a budget; a fast slot or crash game spends it quickly even with a good RTP. The table pairs common budgets and session lengths with games that suit them, using the rule from the beginner section: aim for at least 50 to 100 bets per session.

Two adjustments make any row work better. Cut the stake before you cut the session: halving a €1 stake to €0.50 doubles your bets without changing the edge. And when you want the evening to last, pick the slower format of the same game, such as live roulette instead of RNG roulette. If your budget covers only 20 or 30 bets at the stake you had in mind, that stake is too high for the game.

Where to play the best online casino games in Ireland: our pick, 22BET

Every game on this page is only as good as the version a casino runs and the account you play it from. Our pick for Irish players is 22BET, which puts casino, live casino and sportsbook on one account, so the slot lobby, the live dealer tables and sports betting sit behind one login. New players get +250% on your deposit, the brand is rated 5.0 from 2,748 player reviews, and the cashier offers a wide choice of payment methods, including cards, e-wallets and crypto.

The checks from this page still apply there. Open each game’s info screen and confirm the version before you stake: the RTP, the single zero on the wheel, the 3 to 2 payout on the blackjack felt and the standard commission in baccarat. Bonus wagering, eligible games and the minimum deposit are set out in the terms on the 22BET site, and we don’t quote figures we can’t confirm.

22BET is an offshore operator without a GRAI licence, so its own terms govern verification, limits and withdrawals. No online casino holds a GRAI licence yet, because applications for gaming licences only open during 2027 and 2028. Set a deposit limit when you sign up and keep stakes to the budget plan above; our responsible gambling page lists Irish support if play stops being fun.
