How winnings work (members only)

What 94.5% RTP costs per $100 wagered

What 94.5% RTP means

Expected return = stake × 94.5%
Over $100 of total bets, the long-run average loss is $5.50

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

Features explained (members only)

4 features explained: free spins, pick bonus, sticky wilds, gamble feature

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.

Pick bonus

A bonus game where you choose from hidden items to reveal cash prizes, multipliers or extra features.

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.

Gamble feature

After a win you can risk it on a double-or-nothing guess, such as the colour of a card. It does not improve the game's long-term return.

Strategy tips (members only)

Size your stake to the volatility. Medium-to-high volatility means longer gaps between meaningful wins, with most of the return concentrated in features. Use smaller stakes relative to your budget. A simple rule: bring at least 250 spins' worth of budget, so a $50 budget suggests a stake of about $0.20.

2 more tips and a session planner

Bonus wagering: at 94.5% RTP, clearing $1,000 of wagering costs about $55.00 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.
