About Coin UP Volcano
Lava surges under a compact 4 × 3 base grid, but the bonus doubles its height, and half of that new space starts out sealed. Opening it up is what this game is about, because the top jackpot needs every one of those cells filled.
Inside Coin UP Volcano
Four symbols, taller grid
Any active line holding four symbols launches Hold and Win. The grid grows to 4 × 6, with the top three rows locked. Bonus symbols can carry Mini, Minor and Major jackpots, and Coin Collect gathers every active value.
The Up Row
Modifiers drop into a row above the reels: Reel Up unlocks blocked cells, Mystery Up turns Mystery symbols into guaranteed jackpots, Multi Up adds multipliers and Coin Up boosts values. Each normally affects only the reel it lands on.
Super modifiers
Every Up modifier has a Super version. When one of those appears, its effect stretches across all reels instead of only one, so a single drop can change the whole grid.
