How to play Sea of Riches (members only)

Wins pay for groups of matching symbols that touch horizontally or vertically. Larger clusters pay more, and winning clusters usually disappear to make room for new symbols.

Sea of Riches is played on a 6×6 grid with cluster pays.

Set your stake. Choose your total bet per spin between $0.20 and $200. 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.

How winnings work (members only)

What 96% RTP costs per $100 wagered, the 2,416x max win at a $1 stake

The top prize is capped at 2,416x your stake. On a $1 spin that is $2,416; on $0.20 it is $483.20. When the cap is reached the round usually ends immediately.

Because wins don't depend on lines, every symbol in view can count towards a pay. The paytable lists how many matching symbols each tier needs.

Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.

Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.

What 96% RTP means

Expected return = stake × 96%
Over $100 of total bets, the long-run average loss is $4.00

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

The published hit frequency is 35.3%, meaning roughly one spin in 2.8 returns something — though many of those wins are smaller than the stake.

Features explained (members only)

5 features explained: tumbling reels, cluster pays, free spins, multipliers and more

Tumbling reels

After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.

Cluster pays

Wins are formed by groups of matching symbols touching horizontally or vertically, rather than along lines.

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.

Multipliers

Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.

Wild symbols

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

Strategy tips (members only)

Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.

2 more tips and a session planner

Bonus wagering: at 96% RTP, clearing $1,000 of wagering costs about $40.00 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.
