The top prize is capped at 2,000x your stake. On a $1 spin that is $2,000; on $0.20 it is $400. When the cap is reached the round usually ends immediately.

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.

Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a volatile game.

The published hit frequency is 40.5%, meaning roughly one spin in 2.5 returns something — though many of those wins are smaller than the stake.

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.

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.

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

Sticky wilds

Sticky wilds stay locked in place for several spins or for the rest of a feature, giving every following spin a better chance of connecting wins.

Tumbling reels

After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.

• 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.
