Slots: how they work and who makes them

RTP and the house edge

RTP, return to player, is the share of all stakes a game pays back over a very large number of spins. A 96% RTP means a 4% house edge. It describes the long run across all players, not what will happen in your session.

Some games come in several certified RTP settings, and the operator picks one. So the same title can pay back less at one casino than at another.

Volatility

Volatility describes how wins are spread. Low volatility games pay small amounts more often, while high volatility games pay rarely but can pay larger amounts. Neither type changes the house edge.

No system beats the odds

Every spin is independent. Betting patterns, timing and so-called hot machines do not change the outcome. The only things you control are the stake, the time you play and when you stop.

Browse by provider

Each studio builds its own math and style. Choose a provider to see its slots with RTP, volatility and features.

Playing responsibly

Gambling is entertainment with a cost, not a way to earn money. Play only if you are 18 or older and only with money you can afford to lose. See responsible gambling for tools and help.
