This is an educational guide. House edge and RTP figures are typical industry values and vary by individual game and operator. No game can be beaten in the long run — play for entertainment, not as a way to make money.
What Is RTP in Slots? (And Why It Matters)
RTP stands for "return to player", and it's one of the most useful numbers to understand before you play any slot. It tells you, over the long run, how much of the money staked a game pays back. Here's what it really means — and what it doesn't.
RTP and house edge are two sides of the same coin
If a slot has an RTP of 96%, it returns £96 for every £100 staked across millions of spins. The other 4% is the house edge — the casino's built-in margin. A higher RTP means a lower house edge, so your money tends to last longer.
It's a long-run average, not a promise
This is the part people misread. RTP is calculated over millions of spins. In any single session you might win far more than 96% back — or far less. The short-term swings are down to volatility (or variance), which is separate from RTP: two 96% slots can feel completely different, one paying small wins often, the other rarely but big.
Typical RTP ranges
Most online slots sit between roughly 92% and 97%. A few percentage points sounds small but adds up over time, so checking RTP is a simple way to play smarter.
Where to find it
Good operators publish each slot's RTP in the game's information panel. If you want the lowest house edge of all, table games like blackjack beat slots — see our guide to casino games with the best odds.
