Casino Game Comparison: Edge & Expected Loss Calculator
By Odds Reference Published March 1, 2026 Updated July 19, 2026 Editorial Policy
The casino game you choose determines more about your expected cost than any betting system, strategy adjustment, or lucky streak. A $10 blackjack player using basic strategy loses roughly $3 per hour. The same $10 bettor at an American roulette table loses $16 per hour. Game selection is the highest-leverage decision available.
Last Updated: July 2026
Key Takeaways
- Blackjack with basic strategy offers the lowest house edge at 0.3-0.5%, followed by baccarat banker bet at 1.06% and craps pass line at 1.41%.
- Expected loss per hour = house edge x average bet x hands per hour. A $10 slot player at 600 spins per hour with 4% edge loses $240 per hour in expected value.
- Game speed matters as much as house edge. Roulette has a higher edge than blackjack but plays far fewer rounds per hour, reducing hourly cost.
- A $100 bankroll’s expected survival time ranges from 56 hours (full-odds craps) to about 25 minutes (96%-RTP online slots at $10/spin) — a 130x spread driven mostly by pace, not edge.
- No betting system overcomes house edge. Doubling strategies (Martingale) increase variance but do not change expected loss.

How Much Does Each Casino Game Actually Cost Per Hour?
Expected loss per hour is the product of three variables: house edge, bet size, and game speed. Most players focus exclusively on house edge and ignore speed, which leads to underestimating the cost of fast games like slots. The table below prices out nine common games side by side at a fixed $10 bet.
| Game | House Edge | Hands/Hour | $10 Bet: Hourly Cost |
|---|---|---|---|
| Blackjack (basic strategy) | 0.50% | 60 | $3.00 |
| Craps (pass line + full odds) | 0.37% | 48 | $1.78 |
| Craps (pass line only) | 1.41% | 48 | $6.77 |
| Baccarat (banker) | 1.06% | 72 | $7.63 |
| European Roulette | 2.70% | 35 | $9.45 |
| American Roulette | 5.26% | 35 | $18.41 |
| Online Slots (96% RTP) | 4.00% | 600 | $240.00 |
| Online Slots (98% RTP) | 2.00% | 600 | $120.00 |
| Keno (live) | 25.00% | 6 | $15.00 |
Methodology: house-edge and hands-per-hour figures reflect each game’s standard published rule set. We cross-check these against independent gambling-mathematics references such as Wizard of Odds and the certification framework regulators like the Nevada Gaming Control Board require testing labs to verify before a game goes live.

The slot numbers are striking. Even with a competitive 96% RTP, the sheer volume of spins per hour makes slots the most expensive game on an hourly basis at any given bet size. A $1 slot player loses more per hour than a $10 blackjack player.

How Long Does a $100 Bankroll Actually Last At Each Game?
At expected value, a $100 bankroll survives roughly 56 hours of full-odds craps but only 25 minutes of $10-per-spin online slots at 96% RTP. Dividing bankroll by hourly cost converts an abstract house-edge percentage into the number that actually matters at the table: how long your money lasts.
| Game | $10 Bet: Hourly Cost | $100 Bankroll Survival (EV) |
|---|---|---|
| Craps (pass line + full odds) | $1.78 | 56.2 hours |
| Blackjack (basic strategy) | $3.00 | 33.3 hours |
| Craps (pass line only) | $6.77 | 14.8 hours |
| Baccarat (banker) | $7.63 | 13.1 hours |
| European Roulette | $9.45 | 10.6 hours |
| Keno (live) | $15.00 | 6.7 hours |
| American Roulette | $18.41 | 5.4 hours |
| Online Slots (98% RTP) | $120.00 | 50 minutes |
| Online Slots (96% RTP) | $240.00 | 25 minutes |
This is an EV-based estimate, not a guarantee — it divides a fixed bankroll by the expected hourly cost from the table above. Variance means a real session can bust in minutes on a cold run at any game, or stretch on far longer during a hot one. The gap between rows is still the point: full-odds craps returns roughly 130x the table time of high-speed slots for the same $10 bet and $100 bankroll, almost entirely because it plays 12x slower, not because its edge is dramatically better.
Does Betting Strategy Change Expected Loss?
No. No betting system alters the mathematical expectation of a game with a fixed house edge. The Martingale system (doubling after losses) does not reduce expected loss. Flat betting does not reduce expected loss. Oscar’s Grind does not reduce expected loss.
What betting systems do change is the distribution of outcomes — the variance profile of a session. Martingale concentrates losses into rare catastrophic events while producing frequent small wins. This feels like winning but the expected value remains negative.
The only strategy that changes house edge is learning optimal play in skill-dependent games:
| Game | Without Strategy | With Basic Strategy | Edge Reduction |
|---|---|---|---|
| Blackjack | 2.0-4.0% | 0.3-0.5% | 75-90% |
| Video Poker (JoB) | 3.0-5.0% | 0.46% | 85-90% |
| Craps (adding odds) | 1.41% | 0.37% (5x odds) | 74% |
| Pai Gow Poker | 2.84% | 1.46% | 49% |

How Should You Compare Games for Entertainment Value?
Cost per hour of entertainment is a more practical metric than house edge alone. A low house edge means nothing if the game plays 10x faster than the alternative. Comparing a $5 roulette player against a $0.50 slots player below shows how pace can flip which game is actually cheaper to play.
Consider these two players:
Player A: Plays $5 European roulette. House edge 2.70%, 35 spins per hour. Expected cost: $4.73/hour. Session lasts 3 hours with a $100 bankroll.
Player B: Plays $0.50 online slots at 96% RTP. House edge 4.00%, 600 spins per hour. Expected cost: $12.00/hour. Session lasts 1.5 hours with a $100 bankroll.
Player A pays half as much per hour and plays twice as long. The roulette house edge is higher, but the slower pace more than compensates.
This framing also reveals why casino bonuses require careful analysis. A 100% deposit match with a 30x wagering requirement forces a specific volume of play. The expected loss during that playthrough depends entirely on which game you use to clear the requirement. Our wagering requirement calculator quantifies this precisely.

Which Games Offer the Best Value at Online Casinos?
Our cross-platform RTP tracking found the same slot title, Joker Bombs, running anywhere from 94.11% to 99.01% depending on the operator — a 4.9-point spread that changes expected loss more than any bonus offer. The same slot title can run at meaningfully different settings depending on which casino hosts it.
| Operator | Joker Bombs RTP | House Edge |
|---|---|---|
| Stake.us | 94.11% | 5.89% |
| McLuck | 96.20% | 3.80% |
| High 5 Casino | 99.01% | 0.99% |
That’s a 5x difference in house edge on an identical game. See our cross-platform sweepstakes RTP comparison for the full ten-slot, five-operator dataset, including titles where operators disclose no RTP figure at all. Our analysis of platform reputations covers the broader operator landscape beyond RTP alone.
For table games, the rules are standardized enough that house edge is consistent across platforms. The differences come down to side bets, which almost universally carry higher house edges than base bets. Avoid side bets unless you specifically want higher variance.

FAQ
Q: Which casino game has the lowest house edge?
A: Blackjack with perfect basic strategy has the lowest house edge among standard casino games at 0.3-0.5%, depending on the specific rule set (deck count, dealer soft 17, doubling rules). Video poker on a full-pay Jacks or Better machine comes in second at 0.46%. Both require optimal play — mistakes increase the effective house edge substantially.
Q: How much does it cost per hour to play slots?
A: At $1 per spin with 600 spins per hour (typical online pace) and a 4% house edge (96% RTP), expected loss is $24 per hour. Land-based slots are worse: at 10% house edge and 400 spins per hour, a $1 bettor loses $40 per hour. Bet size and spin rate are the primary cost drivers — the house edge is fixed by the game.
Q: Is roulette a better bet than slots?
A: European roulette (single zero, 2.70% house edge) is substantially better than average slots (4-5% house edge). American roulette (double zero, 5.26%) is roughly equivalent to mid-range slots. However, roulette plays fewer rounds per hour than slots — about 30-40 spins versus 400-600 — so the hourly cost of roulette is often lower despite a similar edge.
Q: How long does a $100 bankroll actually last at each game?
A: At expected value, $100 lasts about 56 hours at full-odds craps, 33 hours at basic-strategy blackjack, 11 hours at European roulette, and roughly 25 minutes at $10-per-spin online slots (96% RTP). These are EV averages from bankroll divided by hourly cost — variance means any individual session can end faster or run much longer.
Q: Where can I verify these house edge numbers myself?
A: House edge is determined by fixed game rules and payout tables, not by any single casino’s results, so it’s independently verifiable. Gambling-mathematics references like Wizard of Odds publish the same figures, and US regulators such as the Nevada Gaming Control Board require certified testing labs to confirm a game’s actual payback matches its stated math before it goes live.
