What does RTP mean in a casino?

Return to player: the percentage of all money wagered on a game that it pays back over a very large number of rounds. 98% RTP means $98 back per $100 wagered on average, over the long run.

Higher is better for the player, because the house edge is lower. A 99% RTP game costs a quarter as much to play, on average, as a 96% RTP game for the same amount wagered.

Is RTP the same as my chance of winning?

No. Win rate is how often a bet pays; RTP is how much of your total wagers comes back on average. A bet can win most of the time and still have a house edge.

Does RTP change after a losing streak?

No. Each round is independent and RTP is fixed by the game’s math. A losing run does not make a win more likely next.

Casino math, explained

What is RTP? Return to player, explained

RTP, or return to player, is the percentage of all money wagered on a game that the game pays back over a very large number of rounds. A game with a 98% RTP returns $98 for every $100 wagered on average, over the long run. The other $2 is the house edge.

RTP: Long-run share of wagers paid back, e.g. 98%
House edge: 100% minus RTP, e.g. 2%
Expected cost: Amount wagered × house edge
What it is not: A prediction of any session or round

RTP and house edge are two sides of one number

House edge is 100% minus RTP. At 98% RTP the house edge is 2%, so over many rounds you can expect to lose about 2% of everything you wager. At 99% RTP it is 1%.

The gap matters more than it looks. Over $1,000 of total wagers, a 99% RTP game has an expected cost of $10 and a 96% RTP game an expected cost of $40, four times as much.

At Havoc Win every game publishes its RTP and house edge on the edge table. Across the catalog they run from about 94% to 99% RTP; the table is the live source.

RTP describes the long run, not your session

RTP is a theoretical average over a very large number of rounds. In any one session you can finish well above or well below it, and a short run of wins or losses says nothing about what comes next: each round is independent. More on that in the gambler’s fallacy.

RTP is also not your win rate. On a 5×5 Mines board with 3 bombs, a single pick is safe 88% of the time, yet the game’s RTP is still set by how the payouts are priced against those odds. Winning often and returning 98% are two different things.

RTP versus volatility

Two games with the same RTP can feel completely different. Volatility is how spread out the results are: low volatility means many small returns, high volatility means long dry spells and rare large hits. RTP tells you the long-run average; volatility tells you how bumpy the road is.

Our odds calculators show both sides for each game, such as how Plinko’s risk setting changes its payout table and how Crash cash-out targets change your chance of reaching them. They use the same tables the games run.

Using RTP to compare games and bonuses

Compare games by house edge: a lower edge means a lower expected cost for the same amount wagered.
Estimate the real cost of a wagering requirement as amount wagered × house edge. The wagering calculator does it for you.
Check that results were not changed after you bet with the provably fair verifier. Fairness and RTP are separate: a provably fair game still has a house edge.
