How to play Coin UP Volcano (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.

Coin UP Volcano is played on a 4×3 grid with 3 paylines.

Set your stake. Choose your total bet per spin between $0.10 and $30. 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.
Optional bonus buy. Where permitted, pay a fixed price to start the bonus directly.

How winnings work (members only)

How wins are paid and capped

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.

Features explained (members only)

5 features explained: multipliers, hold and win, bonus buy, mystery symbols and more

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.

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.

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).

Mystery symbols

Special symbols that all reveal the same randomly chosen regular symbol, which can complete several wins at once.

Fixed jackpots

Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.

Strategy tips (members only)

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.

1 more tip

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.
