Coin Volcano 2 slot: 95.76% RTP, 4 jackpots, 500x Grand

The sequel keeps the family’s strangest property (no ordinary pay symbols) and builds outward from it. The 3x5 reels show blanks and coins, nothing else; no line ever pays in the base game, and the whole product is the bonus round and what feeds it. The verdict on whether the sequel’s trade-off works is in the Coin Volcano 2 review .

Symbols and the board beneath them

The standard coin types return: cash coins with printed stake multiples, jackpot coins tagged with a tier name, Mystery symbols, a Mystery Jackpot symbol and a Collect symbol. A Sticky Coin can land in the base game and wait there for the bonus, as in the original. Filling the middle row with bonus symbols starts the Bonus Game with three re-spins. The sequel’s addition sits under the coins rather than among them: the Volcano Multiplier feature drops up to nine multipliers onto grid cells, a coin on that cell is scaled by it, and two multipliers on the same cell combine, so the board itself becomes part of the value. The Ultra Bonus Game triggers at random and guarantees those multipliers.

Look and feel

Visually it is the original after a budget increase: the volcano moved closer, the grid frame widened, coin faces redrawn for legibility across more positions. The colour coding does real work: cell multipliers and coin values use distinct palettes, which matters once a round has both in play.

Where it sits among its relatives

Against the original , this is breadth over height: more positions, combining multipliers, a lower headline figure. Against 3 Coin Volcanoes , it trades that game’s Life, Multi and Grow volcanoes for the cell board. Players deciding between them should watch one bonus round of each in demo before reading anything further.

The free demo shows the cell board in motion; how the game works walks the round step by step.

Frequently Asked Questions

What are Coin Volcano 2's core numbers?

RTP 95.76%, volatility described as medium to high, a 3x5 grid and a top fixed jackpot (the Grand) of 500x the stake. Released 7 August 2025.

Why is the headline prize lower than the original's?

A deliberate rebalance. The sequel keeps 4 fixed jackpots with the Grand at 500x and spends its value on busier rounds, where multipliers on the same cell combine, instead of the original’s 2,551x advertised peak. Sources differ on the sequel’s absolute max win, so read the figure in your casino’s paytable.

What stake range does the slot accept?

The international build runs $0.10-$100. In Great Britain the legal ceiling is £5 per spin at every licensed operator, £2 if you are 18 to 24, so the upper end of that range never appears in a UK lobby.
