How to play Dolphins Treasure (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.

Dolphins Treasure is played on a 5×3 grid with 9 paylines.

Set your stake. Choose your total bet per spin between $1 and $270. 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 94.1% RTP costs per $100 wagered, the 370x max win at a $1 stake

The top prize is capped at 370x your stake. On a $1 spin that is $370; on $0.20 it is $74. When the cap is reached the round usually ends immediately.

What 94.1% RTP means

Expected return = stake × 94.1%
Over $100 of total bets, the long-run average loss is $5.90

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

The published hit frequency is 35%, meaning roughly one spin in 2.9 returns something — though many of those wins are smaller than the stake.

Features explained (members only)

2 features explained: wild symbols, gamble feature

Wild symbols

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

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. Low volatility means frequent, smaller wins and a smoother balance. It suits longer sessions and bonus wagering, but big multipliers are rare. A simple rule: bring at least 100 spins' worth of budget, so a $50 budget suggests a stake of about $0.50.

2 more tips and a session planner

Bonus wagering: at 94.1% RTP, clearing $1,000 of wagering costs about $59.00 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.
