How to play Mermaids Galore (members only)
Instead of fixed lines, matching symbols on adjacent reels pay in any position, starting from the leftmost reel. The more matching symbols there are on each reel, the more ways the combination pays.
Mermaids Galore is played on a 5×5 grid with 1,200 ways.
- Set your stake. Choose your total bet per spin. 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.
- Trigger the bonus. Land the required scatter symbols to start the free spins feature.
- Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)
What 97.52% RTP costs per $100 wagered, the 7,790x max win at a $1 stake
The top prize is capped at 7,790x your stake. On a $1 spin that is $7,790; on $0.20 it is $1,558. When the cap is reached the round usually ends immediately.
What 97.52% RTP means
Expected return = stake × 97.52%
Over $100 of total bets, the long-run average loss is $2.48
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 50%, meaning roughly one spin in 2.0 returns something — though many of those wins are smaller than the stake.
Features explained (members only)
4 features explained: free spins, wild symbols, bonus buy, fixed jackpots
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.
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).
Fixed jackpots
Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.
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.
3 more tips and a session planner
- 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.
- Bonus wagering: at 97.52% RTP, clearing $1,000 of wagering costs about $24.80 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.
