How winnings work (members only)

What 96.26% RTP costs per $100 wagered, the 3,650x max win at a $1 stake

The top prize is capped at 3,650x your stake. On a $1 spin that is $3,650; on $0.20 it is $730. When the cap is reached the round usually ends immediately.

What 96.26% RTP means

Expected return = stake × 96.26%
Over $100 of total bets, the long-run average loss is $3.74

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

Features explained (members only)

3 features explained: free spins, wild symbols, respins

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.

Wild symbols

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

Respins

Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.

Strategy tips (members only)

Size your stake to the volatility. Very high volatility means most spins lose and a large share of the return comes from rare big features. Treat it as entertainment with a strict budget and a stake of around 0.5% of your session budget or less. A simple rule: bring at least 400 spins' worth of budget, so a $50 budget suggests a stake of about $0.12.

2 more tips and a session planner

Bonus wagering: at 96.26% RTP, clearing $1,000 of wagering costs about $37.40 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
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.
