What does RTP actually mean for my chances of winning?
A worked example
Say a slot is listed at 96% RTP. Across a very large number of spins by all its players, it pays back about $96 for every $100 staked. The other $4 is the house edge. That figure comes from the game's maths and is checked by testing labs over simulated millions of rounds.
Now take one player with $100 and $1 spins. They might be up $300 after twenty minutes or broke after fifteen. Both results fit with 96% RTP, because RTP says nothing about how the returns are spread out.
Volatility is the part you feel
Two games can share an RTP and play completely differently. A low-volatility game pays small wins often. A high-volatility game can go a long time with little, then land something big. Most of a high-volatility game's RTP sits in rare large wins, so most sessions on it end below the average. See volatility for more.
House edge on table games
Table games use the same idea under a different name. European roulette has one zero, which gives the house an edge of about 2.7% on most bets. American roulette adds a double zero and roughly doubles that. Blackjack's edge depends on the rules and on how well you play. In every case it's a long-run average, not a fee taken from each bet.
How to use RTP sensibly
- Compare RTP between versions of the same game; some slots come in several RTP settings, and casinos choose which one to run.
- Look for the figure in the game's own help or info screen rather than a review site.
- Don't read a higher RTP as a better chance tonight. It slightly reduces what you lose on average over a long time.
- Set your budget as if you'll lose it, because over a single session that's a normal result.
