Three numbers describe any casino game’s economics. Players quote the first, the casino cares about the second, and the third is what you actually experience.
RTP — return to player
The percentage a game returns over an enormous number of plays. A 96% RTP slot returns 96% of everything staked, across millions of spins by all players combined.
What it does not mean: that you get 96% of your deposit back. Over a session of a few hundred spins, variance swamps the average completely.
Two things worth knowing:
- The same game ships at different RTPs. Studios commonly supply 96%, 94% and 92% builds of the same title, and the casino chooses. Check the game info panel rather than a review that tested a different version.
- RTP is per game, not per casino. A casino has no single RTP.
House edge
The mirror image: 100% − RTP. A 96% RTP is a 4% house edge.
Useful because it makes games comparable:
| Game | House edge |
|---|---|
| Blackjack (basic strategy, 3:2) | 0.5% |
| Baccarat (Banker) | 1.06% |
| Roulette (French, even money) | 1.35% |
| Roulette (European) | 2.70% |
| Crash games | 3%–5% |
| Slots | 2%–8% |
| Roulette (American) | 5.26% |
| Baccarat (Tie) | 14.4% |
The number nobody quotes: expected loss per hour
House edge alone is misleading, because games run at wildly different speeds. What costs you money is edge × stake × rounds per hour.
| Game | Edge | Rounds/hour | Stake | Expected loss/hour |
|---|---|---|---|---|
| Live roulette | 2.7% | 40 | $5 | $5.40 |
| RNG roulette | 2.7% | 300 | $5 | $40.50 |
| Slots | 4% | 600 | $1 | $24.00 |
| Crash games | 4% | 250 | $2 | $20.00 |
The same roulette game costs eight times more per hour on the RNG table than the live one — identical edge, different pace. This is the most useful and least discussed number in gambling, and it means slowing down is the most effective thing you can do to reduce cost without changing what you play.
Volatility
How the return is distributed over time.
- Low volatility — frequent small wins, slow drift. A small balance lasts.
- High volatility — long dry stretches, rare large payouts. The same RTP delivered in a way that can empty a balance before the good spin arrives.
Two 96% RTP slots can produce entirely different sessions. Almost every complaint that a game “isn’t paying” is a high-volatility game played with a low-volatility bankroll.
Rule of thumb: a high-volatility slot needs a balance that survives 200+ losing spins at your chosen stake. If your balance covers 40 spins, play low volatility.
Putting it together
To make a deposit last:
- Pick a low house edge game — blackjack with basic strategy, baccarat Banker, French roulette
- Play at a slower pace — live tables over RNG, and do not use turbo spin
- Choose volatility that matches your balance
- Check the actual RTP build in the game info panel
To chase a large win instead, invert points one and three and accept that the expected outcome is worse. Both are legitimate choices; they should just be made deliberately.
The thing none of it changes
Every one of these games has a negative expected value. Optimising across them changes how fast you lose, not whether. Treat the numbers as a way to buy more entertainment per unit of money — not as a route to profit.
