Not all casino games deliver equal value – house edges range from under 0.5% in blackjack to over 20% in keno, which means the game you choose directly determines how far your budget goes.
At BonusRadar, we review online casino sites across Europe and test titles based on rules, gameplay depth, bonus features, and player experience – not just return figures.
What makes a casino game worth playing comes down to more than one number. The best online casino games combine clear rules, engaging mechanics, fair certified returns, and strong availability across licensed platforms.
We’ve tested each title on those grounds and explained what you actually need to know before you play.

Blackjack – The Best Skill-Based Casino Game
Blackjack is the most widely played card game in casino history and, in our view, the single best game available at any online gambling platform.
The objective is straightforward – get closer to 21 than the dealer without going over. Each round, players receive two cards face up while the dealer shows one.
Players can then choose between several actions:
- hit, which means taking one more card;
- stand, which means keeping the current hand;
- double down, where the player doubles the original bet and receives exactly one additional card;
- split, which allows two cards of the same value to be separated into two individual hands.
The dealer reveals their hidden card and draws to fixed rules, standing on 17 or higher.
What separates blackjack from most casino games is that your decisions change the outcome. A player using basic strategy (a publicly available, mathematically optimized decision chart) reduces the house edge to around 0.5% on a standard six-deck game.
The original basic strategy was calculated by Roger Baldwin and colleagues in 1956 and has been refined through computer simulations since. It tells you exactly when to hit, stand, double, or split based on your cards and the dealer’s visible card.
The most important rule variants to know are the blackjack payout (3:2 is standard; 6:5 costs players significantly more over time), whether the dealer hits or stands on soft 17 (standing favors the player), and deck count (fewer decks slightly favor the player).
Popular online RNG titles include BetSoft’s Blackjack, Playtech’s Blackjack Pro, and NetEnt’s Classic Blackjack, all available across most MGA-licensed casinos.
European Roulette – The Best Game for Pure Betting Variety
Roulette is one of the oldest and most recognizable casino games in the world. A croupier spins a wheel with numbered pockets and releases a small ball in the opposite direction.
Players bet on where the ball will land before the spin – on a specific number, a color (red or black), an odd or even number, a range of numbers, or several other combinations. Payouts range from 1:1 on even-money bets (red/black, odd/even) up to 35:1 on a single number.
Three main variants exist, and the choice between them has a direct mathematical impact. European roulette uses a single-zero wheel with 37 pockets, giving it a house edge of 2.70%.
American roulette adds a double-zero pocket, raising the edge to 5.26%. There is no gameplay reason to choose this version when European is available.
French roulette is widely seen as the most player-friendly version of the game. It uses the same single-zero wheel as European roulette, but includes the La Partage rule.
Thanks to this rule, when the ball lands on zero, players lose only half of an even-money bet, while the other half is returned. This cuts the house edge on those bets to 1.35%.
Among specific titles, Evolution Gaming’s Lightning Roulette is one of the most-played live roulette games globally, adding random multipliers up to 500x on straight-up numbers each round. Pragmatic Play’s Mega Roulette uses a similar mechanic.
Both keep standard European roulette rules as their base. For standard play without multipliers, NetEnt’s European Roulette and Playtech’s European Roulette Pro are consistently available at licensed casino sites.
Baccarat – The Best No-Skill Table Game
Baccarat is a comparing card game played between two hands – the Player and the Banker. Despite the names, you’re not playing against the dealer personally; you’re betting on which hand will come closest to a total of 9.
Cards are dealt from a shoe of 6 or 8 decks. Number cards count at face value, aces count as 1, and tens and face cards count as 0. If a hand’s total exceeds 9, only the second digit counts – a hand of 7 and 8 totals 15, which counts as 5.
The rules for drawing a third card are fixed and automatic. Neither the player at the table nor the dealer makes a decision about it.
A third card is drawn for the Player hand if the total is 5 or less, and for the Banker hand according to a specific set of rules based on both hands’ totals. The player’s only active decision is which bet to place before the round begins.
Three options are available – Banker (house edge 1.06%), Player (house edge 1.24%), and Tie (house edge approximately 14.36%). The Tie bet should be avoided regardless of its payout.
Baccarat is the game of choice for high-volume players because of its simplicity and low variance. Popular live baccarat titles include Evolution Gaming’s Speed Baccarat, which completes a round in approximately 27 seconds, and Pragmatic Play’s Baccarat Lobby, which offers standard and speed variants at multiple bet limits.
Craps – The Best High-Action Table Game
Craps is a dice game in which players bet on the outcome of a roll or series of rolls of two standard six-sided dice. The game has a reputation for complexity, but the core structure is simple once you understand two key phases.
The come-out roll starts a new round. If the shooter rolls a 7 or 11, Pass Line bets win; if they roll 2, 3, or 12, Pass Line bets lose.
Any other number (4, 5, 6, 8, 9, or 10) becomes the point, and play continues until either the point is rolled again (Pass Line wins) or a 7 appears (Pass Line loses).
The vast majority of craps bets are worth ignoring. The center proposition bets (Any 7, Any Craps, Hardways) carry house edges ranging from 9% to 16.67%.
The bets that matter are Pass/Don’t Pass (house edge 1.41% and 1.36%) and Odds bets, placed behind a Pass or Don’t Pass bet once a point is established.
Odds bets pay at true probability with zero house edge – the only bet of this kind in any casino game. At a 5x odds table, the combined edge on Pass + maximum odds drops to approximately 0.33%.
Online craps is available at most major licensed casinos. Playtech’s Craps and Microgaming’s Craps both follow standard Las Vegas rules and include visual tutorials that help new gamblers identify the key bet areas on the layout before playing for real money.
Pai Gow Poker – The Best Game for Extended Sessions
Pai Gow Poker is a casino card game based on the classic Chinese game Pai Gow. It is played with a standard 52-card deck and one joker. Each player is dealt seven cards and must divide them into two hands – a five-card high hand and a two-card low hand.
To win, both hands must beat the dealer’s corresponding hands. If the player wins only one hand, the round ends in a push, and the original bet is returned. If neither hand wins, the player loses the wager.
The Joker acts as a semi-wild card. It can complete a straight, flush, or royal flush in the five-card hand, or count as an ace otherwise. Setting the hands correctly, a concept called “house way,” is the main skill in Pai Gow.
Most online versions offer a “house way” button that arranges cards according to the dealer’s standard method, a useful reference for new players.
Approximately 41% of all hands end in a push, which makes Pai Gow the most bankroll-preserving table game available.
Players who take the Banker role – offered once per rotation – reduce the house edge from 2.84% to approximately 1.42% by gaining the tie-breaking advantage. This role should never be declined when offered.
Playtech’s Pai Gow Poker is the most widely available version across online casino games platforms and includes a full rules tutorial and house-way reference within the game interface.
Live Dealer Blackjack – The Best Live Casino Experience
Live dealer blackjack follows the same rules as standard blackjack but replaces the RNG with a real human dealer streamed in real time from a studio.
Players interact with the game through a betting interface while watching a live video feed of the actual cards being dealt from a physical shoe. The experience bridges the gap between solo online play and a visit to a physical casino.
Two providers dominate this category. Evolution Gaming operates studios in Riga, Tbilisi, and Malta. Their most-played title is Infinite Blackjack, where unlimited players bet on the same hand simultaneously, each making independent hit/stand/double/split decisions.
Evolution also offers Power Blackjack (enhanced double-down payouts, no 10-value cards) and Free Bet Blackjack (house-funded doubles and splits on qualifying hands).
Pragmatic Play’s live blackjack studio in Bucharest operates multiple table variants, including standard blackjack, ONE Blackjack (a single-player format), and Azure Blackjack with enhanced side bet options.
All Pragmatic Play live tables use an 8-deck shoe with the dealer standing on all 17s – the most favorable standard rule configuration for players.
Side bets, including 21+3 (a poker combination of the player’s two cards and the dealer’s up card) and Perfect Pairs, are available at most tables but carry lower returns than the main game and are entirely optional.
Jacks or Better – The Best Video Poker Game for Beginners
Jacks or Better is the original video poker format. The game uses a standard 52-card deck. Players receive five cards, choose which to hold and which to discard, then draw replacements.
Payouts begin at a pair of Jacks or better and scale up through two pair, three of a kind, straight, flush, full house, four of a kind, straight flush, and royal flush.
The paytable variant is the single most important thing to identify before playing any Jacks or Better game. The 9/6 full-pay version, which pays 9 coins for a full house and 6 for a flush per coin bet, returns 99.54% with optimal strategy, per Wizard of Odds.
Paytables marked 8/5, 7/5, or lower significantly reduce the return; an 8/5 paytable drops RTP to 97.30%. Always check the full house and flush payouts before playing.
Betting the maximum five coins per hand is essential because it unlocks the 800x royal flush payout instead of the standard 250x – a difference that accounts for roughly 2% of total expected return over time.
Complete strategy charts for 9/6 Jacks or Better are freely available and memorizable in a few hours. The most widely available online versions are IGT’s Jacks or Better and Microgaming’s Jacks or Better, both of which offer the 9/6 paytable on most MGA-licensed online casino platforms.
Deuces Wild – The Best Video Poker Game for Experienced Players
Deuces Wild is a video poker variant in which all four 2s act as wild cards; each can substitute for any other card to complete the best possible hand. This changes the entire hand hierarchy. The minimum qualifying hand shifts from a pair of Jacks to three of a kind.
The payout ladder adds hands unique to wild card play, five of a kind, wild royal flush, and four deuces, which is the highest-paying hand below a natural royal flush.
The Full Pay version of Deuces Wild returns 100.76% with perfect strategy according to Wizard of Odds – the only standard casino game with a theoretical gambler advantage at correct play. In practice, this version is increasingly rare.
Most online operators offer short-pay variants that reduce payouts on certain hands without clearly advertising the change.
The key paytable values to verify for a full-pay game are four deuces paying 200x, wild royal flush paying 25x, and five of a kind paying 15x.
Deuces Wild strategy is more complex than Jacks or Better because the presence of wild cards creates many more hand possibilities.
However, complete strategy charts are publicly available, and the game rewards players who take the time to learn them.
Microgaming’s Deuces Wild and IGT’s Deuces Wild are the most commonly available versions at licensed platforms, and both offer a paytable review screen before the game begins.
Online Slots – The Best Category for Variety and Jackpots
Slots are the most played game category across all online gambling sites globally, and for good reason. No other format offers the same combination of variety, accessibility, and win potential from a small initial bet.
The core mechanic is consistent regardless of the title – spin the reels, match symbols across one or more paylines, and receive a payout based on the combination and your bet size.
Modern video slots typically feature 5 reels and between 10 and 1,024 ways to win, along with bonus features that distinguish one title from another.
Bonus features are what separate memorable slots from forgettable ones. Free spins rounds are the most common, triggered by landing scatter symbols anywhere on the reels, usually three or more.
Multipliers attached to free spins can significantly increase a session’s top end; Pragmatic Play’s Sweet Bonanza offers multipliers up to 100x during its free spins round.
Expanding wilds, cascading reels, and hold-and-win mechanics each create distinct gameplay loops. NetEnt’s Starburst is one of the most-played slots ever released and uses expanding wilds with re-spins as its central mechanic – simple, fast, and immediately accessible.
Pragmatic Play’s Wolf Gold features a Money Respin bonus with fixed jackpots, while Gates of Olympus by Pragmatic Play uses a tumble mechanic with multipliers that can stack across multiple consecutive wins.
For players seeking the highest base-game returns, Mega Joker by NetEnt reaches 99% RTP in Supermeter mode, and Book of 99 by Relax Gaming offers the same 99% RTP across all play modes, with a maximum win of 5,000x stake.
For jackpot potential, Mega Moolah by Microgaming has produced confirmed multi-million euro payouts and remains the most recognizable progressive jackpot slot in Europe. The jackpot is funded by a small contribution from each spin across the entire network of players.
Keno – The Best Game for Lottery-Style Play
Keno is a lottery-style game available at most online casino platforms as a specialty title. Players select between 1 and 20 numbers from a grid of 80, place a bet, and then watch as 20 numbers are drawn at random.
Payouts are based on how many of your selected numbers match the draw, with the multiplier increasing as more of your numbers match. The game requires no skill or strategy. Each draw is independent, and the outcome cannot be influenced by the player.
Keno’s appeal is its simplicity and low entry cost. Minimum bets at most online platforms start from €0.10 per ticket.
Some players use personal number systems or frequency tracking, but these have no mathematical effect – the draw is purely random. Most versions include auto-pick and speed mode options.
Online versions from major providers include Microgaming’s Keno and Habanero’s Keno, both of which are available at most licensed casinos and include clear payout tables for every spot count.
Some platforms offer jackpot-linked keno variants where hitting a specific number of matches on the maximum ticket triggers a progressive prize.
The house edge on standard keno ranges from 20% to 25%, significantly higher than that of table games. Keno belongs in the entertainment category rather than the value-seeking category, and is best played in short sessions with a fixed budget.
How We Ranked the Best Casino Games?
At BonusRadar, we evaluate every game across ten criteria before including it in any ranking. The list below reflects the process applied to games in European regulated markets.
Game Popularity
Popularity reflects genuine player feedback at scale. A game played by millions across regulated platforms has been tested in conditions no internal audit can fully replicate.
We weigh popularity as a signal of real player appeal. Unpopular titles get delisted, and popular ones get maintained and updated by their providers.
Return to Player (RTP)
RTP directly influences how we score every game on this list. A title with a certified return above 99% scores higher than a comparable game at 95%, all else being equal, because over millions of rounds, that gap translates into real money retained by players.
We weigh RTP alongside gameplay and features, not as a standalone metric, but any game below 94% requires exceptional qualities elsewhere to make the ranking at all.
Bonus Features
The quality of bonus features determines a game’s ceiling. In slots, this means free spins, multipliers, and jackpot structures.
In table games, it means side bets and rule variants that add strategic depth without degrading the core odds. We evaluate whether bonus features genuinely add value or merely increase house advantage.
Graphics and Design
Visual quality and interface design affect a game’s score based on how directly they serve gameplay. A cluttered layout that obscures bet limits, hides the paytable, or makes active buttons hard to identify on a touchscreen costs a game points regardless of how strong its underlying odds are.
Games that use design to confuse players, for example, by making the Tie bet in baccarat more visually prominent than the Banker bet, score lower. Clean, functional design that keeps the player informed and in control scores higher.
Gameplay Mechanics
Mechanics determine why a game is worth returning to. We ask how quickly a new player can become competent and whether rules are transparent.
Blackjack and Jacks or Better score highest – both have complete publicly available strategy references. Craps scores lower on initial accessibility but improves once the core bet types are understood.
Mobile Compatibility
Most online casino sessions start on a smartphone. Every game on this list has been tested for touch interface usability, load speed, and video stability on standard 4G connections for live dealer titles.
Software Provider
Provider identity is a proxy for reliability and fairness. We include only games from studios holding active MGA (Malta Gaming Authority) or UKGC (UK Gambling Commission) licenses – NetEnt, Pragmatic Play, Evolution Gaming, Relax Gaming, Microgaming, Playtech, and IGT, all of which submit to regular independent audits.
User Experience
A game’s UX covers everything from loading to session end. Key factors include how easily rules and paytables are accessed mid-game, interface responsiveness, and how win amounts are displayed.
For live dealer games, this also includes dealer professionalism and how the game handles connection interruptions.
Jackpot Potential
Higher confirmed win ceilings push a game’s ranking up because maximum win potential is one of the primary reasons players choose a title in the first place.
A slot with a documented 5,000x cap attracts a different and larger audience than one capped at 500x, which directly influences its popularity score.
Payout Frequency
Hit rate determines how long your budget lasts within a session. A slot with a 30% hit rate depletes a bankroll faster than one with 50% hit rate at identical RTP because fewer spins return anything at all.
Low-volatility games suit players with smaller budgets or shorter sessions; high-volatility games suit those willing to absorb a longer losing streak for a larger potential payout.
Tips for Players How to Choose the Most Fun Game for Yourself
The right casino game is the one that matches how you actually want to play — not the one with the theoretically best odds.
Start by identifying what kind of experience you’re looking for, then use the criteria below to narrow down your options within that category.
- If you enjoy making decisions and want skill to matter, blackjack and video poker are the right categories. Both have complete strategy references that you can learn before playing. Basic strategy blackjack and 9/6 Jacks or Better are the two best online casino games in this group – straightforward to learn, widely available, and genuinely rewarding to play correctly over time.
- If you prefer a social or atmospheric experience without needing to master strategy, live dealer blackjack and live roulette are the strongest options. Evolution Gaming and Pragmatic Play’s live studios offer a real casino environment through your screen. The rules are identical to their RNG counterparts, and the dealers are professional and consistent. For roulette specifically, Lightning Roulette and Mega Roulette add multiplier mechanics that increase excitement without changing the core game.
- If you want variety and entertainment above all, the slots category has no equal. Start with well-reviewed titles from established providers (Starburst, Wolf Gold, Sweet Bonanza, Gates of Olympus) rather than unfamiliar titles from unknown studios. Low-volatility slots like Starburst suit smaller budgets and longer sessions; high-volatility titles like Gates of Olympus suit players targeting a larger single win.
The practical checklist below covers what to confirm before committing to any title on a new online gambling site.
- Check that the game is available at a licensed casino regulated by the MGA, UKGC, or an equivalent regulator.
- Review the paytable or odds structure before placing your first bet. This information must be accessible in the game.
- Match volatility to your session budget. High volatility requires a deeper bankroll to absorb variance.
- Confirm the RTP is published and matches the provider’s official figure, not an operator-adjusted version.
- Test on mobile first if you plan to play primarily on a smartphone.
The best online casinos make all of this information accessible without requiring a support request. Under MGA and UKGC regulations, licensed operators must display RTP figures and game rules within the interface.
Any platform that omits or obscures this information is not meeting the standard for a regulated operator and is not one the BonusRadar team recommends.
