About the game
A 3x3 slot with no ordinary paying symbols at all: only coins, and they pay by being collected rather than by lining up. Landing enough of them locks the field into respins, and the round ends either on a jackpot or on the sum of everything caught on the grid.

Coin Volcano is built on a "nothing extra" principle: a small 3x3 grid, coins and a volcano that can boost the round at any moment. There are no regular paying symbols in the game; everything is decided by coins and bonuses on the Hold and Win mechanic. The 3 Oaks slot came out in summer 2023, with a stated RTP of 95.66%, medium volatility and a max win of 2551x.
How the game works
Coins with cash values and jackpot labels land on the 3x3 grid. They pay when collected rather than on classic lines. In the base game, a collect symbol shaped like a red hot ball can appear: it gathers the visible coins and jackpots and adds them to your win.
Two bonuses
The right symbols in the middle row unlock one of two bonus modes. In the classic bonus, the volcano multiplier can trigger at any point in the round. In the ultra bonus, volcano multipliers are guaranteed throughout the whole game, which is why it is considered more valuable.
Respins and jackpots
In the bonus, coins lock on the grid and the empty cells spin in respin mode. Each new coin extends the round. The finale depends on how the grid fills up: either a jackpot or the sum of everything you managed to catch. A full grid unlocks the top jackpot.
How it differs from 3 Coin Volcanoes and Coin Volcano 2
Later 3 Oaks released games based on this slot, such as 3 Coin Volcanoes on a 4x3 grid and Coin Volcano 2. They have their own grids and their own jackpots. The original Coin Volcano remains the most compact: a 3x3 grid and two bonuses.
Who it suits
The game is for those who do not want to keep track of dozens of symbols and lines. Medium volatility and short spins make sessions smoother, but the bonuses still do not arrive on schedule. Try demo mode and set your budget in advance.
