What RTP costs you
Compare two slots: the average cost of the same session at each RTP.

60.00Average cost on slot B
25.00Slot A saves you, on average
RTP is a long-run average over millions of spins. Over a single session the result can be far above or below it; the RTP tells you the price you pay on average.
| RTP | House edge | Average cost of 1,000 spins at 1 | Average cost of 1,000 spins at 0.20 |
|---|---|---|---|
| 99% | 1% | 10.00 | 2.00 |
| 98% | 2% | 20.00 | 4.00 |
| 97% | 3% | 30.00 | 6.00 |
| 96% | 4% | 40.00 | 8.00 |
| 95% | 5% | 50.00 | 10.00 |
| 94% | 6% | 60.00 | 12.00 |
| 92% | 8% | 80.00 | 16.00 |
| 90% | 10% | 100.00 | 20.00 |
Every point of RTP is worth 10 per 1,000 spins at a stake of 1: small per spin, large over a long session.
Questions
What is RTP in slots?
Return to player: the share of all money staked that a slot pays back over the long run. A 96% RTP slot returns 96 of every 100 staked on average, so the cost of playing it is 4% of your stakes. The rest is the house edge.
Which slot has the highest RTP?
Of the 35 slots in our list, all checked on the studios’ own websites, the highest published RTP is 99%: Book of 99 (Relax Gaming) and Mega Joker (NetEnt). 23 of them publish an RTP of 97% or more.
Does a higher RTP mean you win more?
It means you lose less on average over a long run of spins. Over one session anything can happen, and a high-volatility slot swings much more than a low-volatility one with the same RTP.
Why do casinos offer different RTPs for the same slot?
Studios release some slots in several RTP versions, and each casino chooses which one to offer. In our list, Push Gaming publishes 97.03% and 94.67% for Wild Swarm, and Quickspin publishes 97% and 90% for Big Bad Wolf. The RTP we show is the highest the studio publishes, so check the game’s info screen for the version your casino runs.
How can I check a slot’s RTP?
Open the game’s help or information screen: most slots show the RTP of the version you’re playing there. Compare it with the figures the studio publishes for that game.
