Casino Game Comparison: House Edge and Expected Loss Calculator
Last Updated: March 1, 2026
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.

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.
- 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.
| 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 |
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.

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.
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 analysis of RTP configurations across online platforms shows meaningful variation by operator. The same slot title can run different RTP settings depending on which casino hosts it.
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.
