How to play Wombaroo (members only)

Wins are paid when matching symbols land on an active payline, usually left to right starting from the leftmost reel. Your total stake is spread across the lines, and each line win is the line bet multiplied by the symbol's paytable value.

Wombaroo is played on a 5×3 grid with 20 paylines.

Set your stake. Choose your total bet per spin between $0.20 and $40. Wins are paid as multiples of this stake.
Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.
Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.

How winnings work (members only)

What 95.42% RTP costs per $100 wagered, the 4,000x max win at a $1 stake

The top prize is capped at 4,000x your stake. On a $1 spin that is $4,000; on $0.20 it is $800. When the cap is reached the round usually ends immediately.

What 95.42% RTP means

Expected return = stake × 95.42%
Over $100 of total bets, the long-run average loss is $4.58

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

The published hit frequency is 21.86%, meaning roughly one spin in 4.6 returns something — though many of those wins are smaller than the stake.

Features explained (members only)

3 features explained: hold and win, wild symbols, sticky wilds

Hold and win

Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.

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.

Strategy tips (members only)

Size your stake to the volatility. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.

2 more tips and a session planner

Bonus wagering: at 95.42% RTP, clearing $1,000 of wagering costs about $45.80 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.
