How the game works
- Four-symbol trigger. Four matching symbols on either of the two active lines start the BONUS GAME with three respins.
- Respin round. Mini, Minor and Major jackpots can show up. A Mystery Jackpot symbol uncovers one of them, a Mystery symbol turns into some other symbol, and a Boost symbol sweeps up every value on display.
- Grand jackpot. Filling the screen may deliver the Grand, worth x500.
- Three volcanoes. When bonus symbols land on an active line in the main game, green, red and blue fire effects flare up and wake the volcanoes above the reels.
- Boosters. Life restores the respin counter, Multi releases multipliers that merge if they fall in the same cell, and Grow adds two extra rows to the grid. The fire effects persist through the bonus and can bring in more boosters.
- Royal jackpot. With Grow active, filling the enlarged grid awards the Royal, set at x2000.
- Lucky Eruption. This extra can launch the bonus game at random with at least two boosters already switched on.

Player reviews
Die drei Vulkane sind eine gute Idee. Besonders der Effekt mit den zusätzlichen Reihen gefällt mir, weil sich die Bonusrunde dadurch anders anfühlt. Bisher nur kleinere Treffer, trotzdem nett.
Sur 3 Coin Volcanoes, j'aime surtout les différents volcans qui modifient le bonus. C'est assez clair une fois qu'on a compris les couleurs. Pas de jackpot chez moi, mais c'était plaisant.
The three volcano effects sounded promising, but I found the regular spins painfully slow. Even the bonus felt cluttered rather than exciting, and the small returns didn't make up for all that waiting.
3 Coin Volcanoes definitely throws more at you than the original. Took me a few rounds to figure out what each coloured fire meant, and I still think the base spins drag a little. But when the bonus finally starts, it's good fun.
Having three different volcano effects is what makes this version interesting to me. The extra rows and multipliers can change the mood of a bonus round pretty quickly. Fun to watch.
The bonus has more going on than I first realised. I especially like the life refill when it appears; an extra chance always feels good. The regular spins could be livelier though.
