How winnings work (members only)

How wins are paid and capped

Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.

Features explained (members only)

4 features explained: free spins, bonus buy, megaways, multipliers

Free spins

A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.

Bonus buy

Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).

Megaways

A licensed mechanic where the number of symbols on each reel changes every spin, so the number of ways to win can run into the hundreds of thousands.

Multipliers

Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.

Strategy tips (members only)

Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.

1 more tip

Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
