Casino games with the best odds (ranked by maths)
Walk into any casino — online or otherwise — and you're surrounded by choices. Slots with flashing lights. Roulette wheels spinning. Blackjack tables humming. But here's something most players don't think about: the game you pick matters far more than any "strategy" or betting system you'll ever use.
Some games will grind through your bankroll slowly. Others will chew it up in minutes. The difference comes down to one number: the house edge. It's the casino's built-in mathematical advantage, expressed as a percentage of every bet you make. And it varies wildly depending on what you're playing.
So let's go through the major casino games, ranked from best to worst odds, with real numbers instead of vague promises.
Blackjack: the gold standard
If you're looking for the best odds in a casino, blackjack is where you start. With perfect basic strategy on a standard 6-deck game, the house edge drops to about 0.5%. That's fifty cents for every $100 wagered. No other common casino game gets that low.
The catch? You have to actually learn basic strategy. Playing by gut or going with "feelings" pushes the house edge up to 2–3%, which puts you in roughly the same territory as roulette. The cards don't change. Your decisions do.
Basic strategy isn't complicated — it's a set of rules telling you when to hit, stand, double down, or split based on your hand and the dealer's upcard. You can keep a chart open on your phone while playing online. Nobody's stopping you, and it's one of the genuine perks of playing blackjack on the internet.
Table rules matter too. A game paying 3:2 on natural blackjack is standard. If you see 6:5, walk away — that single rule change adds about 1.4% to the house edge. Dealer standing on soft 17 is worth another 0.2% in your favour. These details might seem small, but over hundreds of hands they're the difference between a reasonable session and an expensive one.
Baccarat: simpler than you'd think
Baccarat has a reputation for being fancy and intimidating, but it's actually one of the simplest games in the casino. You bet on Player, Banker, or Tie. Cards are dealt. You don't make any decisions during the hand. That's it.
The Banker bet carries a house edge of 1.06% (after the standard 5% commission on wins). The Player bet sits at 1.24%. Both are excellent — solidly in the top tier of casino bets.
The Tie bet? That's at 14.36%. It's one of the worst bets you can make anywhere. The payout looks attractive at 8:1, but the true odds are closer to 9:1. The gap between the payout and the probability is where the casino makes its money — and it makes a lot on ties.
Baccarat's strength is its simplicity. There's no strategy to learn, no decisions to agonise over, and the odds are good as long as you stick to Player or Banker. It won't give you the same low edge as perfect blackjack play, but you can't mess it up either.
Craps: surprisingly good (if you know which bets)
Craps looks chaotic. People shouting, dice flying, dozens of betting options spread across a table that resembles an alien circuit board. But underneath the noise, some of the bets at a craps table are among the best in the casino.
The Pass Line bet has a house edge of 1.41%. The Don't Pass bet is slightly better at 1.36%. Both are straightforward and easy to understand once you've watched a few rounds.
Here's where craps gets interesting: the Odds bet. After a point is established, you can place an Odds bet behind your Pass or Don't Pass wager. This bet pays at true odds — meaning zero house edge. Literally zero. It's the only bet in the casino with no built-in advantage for the house. The more you bet on Odds relative to your flat bet, the lower your overall edge becomes.
But craps also has some genuinely terrible bets. Proposition bets on specific numbers or combinations carry edges of 9–16%. The "Any 7" bet has an 16.67% house edge. Hardway bets sit around 9–11%. Stick to Pass/Don't Pass with maximum Odds, and you're playing one of the best games available. Scatter your chips across the proposition section, and you're playing one of the worst.
Video poker: the hidden gem
Video poker doesn't get the attention it deserves. With optimal play on the right machine, some variants offer a house edge below 0.5% — competitive with blackjack and arguably easier to play correctly.
Jacks or Better (the most common variant) with a 9/6 pay table gives back 99.54% to the player. That's a house edge of just 0.46%. Full-pay Deuces Wild returns 100.76% with perfect strategy — meaning the player actually has a slight mathematical edge. These machines are rare online, but they exist.
The catch is the pay table. Casino operators can adjust the payouts on video poker machines, and many do. A "short pay" Jacks or Better (8/5 or worse) drops the return below 97%, pushing the house edge above 3%. Always check the pay table before you play. On Jacks or Better, look for 9 coins for a full house and 6 for a flush per coin bet. Anything less and you're giving up value.
Learning optimal video poker strategy takes more effort than blackjack basic strategy, but the resources are freely available online. And like blackjack, you can play with a strategy chart in front of you when you're online.
Roulette: not as bad as you'd think
Roulette's reputation sits somewhere between blackjack and slots in most players' minds, and the maths backs that up — with one big caveat.
European roulette (single zero) has a house edge of 2.7% on all standard bets. Red or black, odd or even, single numbers, splits, streets — they all carry the same 2.7% edge. It doesn't matter how you spread your bets. The maths doesn't change.
American roulette (double zero) jumps to 5.26%. That extra green pocket nearly doubles your expected losses. If you've got a choice — and online you almost always do — play European. Always.
French roulette is even better. The "La Partage" rule returns half your even-money bet when the ball lands on zero, cutting the house edge to 1.35% on those bets. That puts it in baccarat territory. Not bad at all for a game that requires no skill or strategy decisions.
One thing roulette won't ever do: respond to patterns. No system based on tracking previous results will change your odds. The wheel has no memory. Every spin is independent. The Martingale system, the Fibonacci, the whatever-you-read-on-a-forum system — none of them work. They can't, because the maths doesn't allow it.
Slots: the full range
Slot volatility and RTP vary more than any other game category. You can find slots with a 98% RTP (2% house edge) and slots with 90% RTP (10% house edge). That's a fivefold difference in expected cost per spin.
The average online slot sits around 95–96% RTP, which translates to a 4–5% house edge. That's significantly worse than blackjack, baccarat, or craps — but it's not catastrophic. And some high-RTP slots like Mega Joker (99%), Blood Suckers (98%), or Starmania (97.87%) compete reasonably well with table games.
The problem with slots isn't just the edge. It's the speed. You can spin 600+ times per hour online. At $0.50 per spin with a 4% house edge, that's $12 of expected losses per hour. Compare that to live blackjack at $10 per hand (50 hands/hour, 0.5% edge): your expected hourly loss is $2.50 despite betting twenty times more per hand.
Speed kills bankrolls. If you're going to play slots, slow down. Set auto-spin limits. Check the RTP before you play — it's usually in the game's info screen. And manage your bankroll carefully, because the combination of high speed and moderate house edge burns through money faster than most players realise.
The full picture
Here's how the major casino games stack up, ranked by house edge from best to worst:
| Game | Best bet | House edge |
|---|---|---|
| Blackjack (basic strategy) | Main hand | 0.5% |
| Video poker (9/6 JoB) | Optimal play | 0.46% |
| Craps | Don't Pass + Odds | 0.37–1.36% |
| Baccarat | Banker | 1.06% |
| French roulette | Even money (La Partage) | 1.35% |
| European roulette | Any standard bet | 2.7% |
| Slots (high RTP) | 96–98% RTP games | 2–4% |
| American roulette | Any standard bet | 5.26% |
| Slots (low RTP) | Below 94% RTP | 6–10%+ |
The gap between the top and bottom of that table is enormous. Playing blackjack with basic strategy costs you roughly one-tenth of what a low-RTP slot costs per dollar wagered. Over a three-hour session, that's the difference between losing $7 and losing $70 in expected value.
What this actually means for you
Knowing the odds doesn't guarantee you'll win. Nothing does — the house always has an edge, and short-term results are driven by variance, not expected value. You can play perfect blackjack and lose your entire session bankroll. You can spin a terrible slot and hit a jackpot. That's how probability works.
But over time, game selection is the single biggest lever you have. Pick the right game and play it correctly, and you'll lose less money per hour of entertainment. That's the realistic goal here: not beating the casino, but making your entertainment budget last longer and giving yourself more chances to walk away with a win.
A few practical guidelines worth remembering. Learn basic strategy if you want to play blackjack — there's no point sitting at the lowest-edge game in the casino and playing it badly. Check the RTP before spinning any slot. Avoid American roulette when European is available. Skip the Tie bet in baccarat. And at craps, stick to Pass/Don't Pass with Odds. These aren't tricks. They're just maths.
And whatever you play, set a budget before you start. The house edge tells you what the game will cost on average. Progressive jackpots add variance but don't change the fundamental edge. Decide what you're comfortable spending, treat it as the price of entertainment, and stop when you hit your limit. That's the best "strategy" in any casino.
