Coin Volcano 2 review: 3x5 grid, Ultra Bonus, 4 jackpots
- 95.76%RTP
- Grand 500xMax win
- 3x5Layout
- Medium to highVolatility
Coin Volcano 2, released on August 7, 2025, keeps the coin-collect DNA of Coin Volcano and stretches it across a 3x5 grid. The useful question is “what changes?”. Filling the middle row with bonus symbols starts the Bonus Game with three respins, and a Sticky Coin works as in the original. The Volcano Multiplier feature drops up to nine multipliers, and multipliers on the same cell combine. The Ultra Bonus Game triggers at random with guaranteed multipliers, and a Boost Bonus Game, sold only through Buy Bonus in select regions, starts its multipliers at x5. The four fixed jackpots are Mini 10x, Minor 20x, Major 50x and Grand 500x, the Grand for filling all 15 positions. Add a top jackpot of 500x (the original advertises 2,551x) and a wider bet range of $0.10-$100.

The choice comes down to one trade-off: the original concentrates its potential in a high ceiling and a single mechanic; the sequel spreads it across more frequent bonus layers. If you play for the feeling of progression inside the bonus, take the sequel; if you play for the ceiling, stay with the original.
Before you bet
Compare the two rhythms in demo first: Coin Volcano 2 demo and Coin Volcano demo . On Android, access runs through the APK or the browser . Jackpot values and Bonus Buy availability vary by casino version, so check the paytable in your lobby. Note too that, as a 2025 release, the sequel has not reached every Canadian catalogue yet (the casino page covers how to check). The slot fact sheet condenses the sequel’s symbols and math, and the game guide traces a full round from spin to payout. Play responsibly: 19+ in most provinces, 18+ in Quebec, Alberta and Manitoba.
Two practical questions follow most people to the sequel. The app page explains how one operator install ends up carrying both Coin Volcano titles, so you are not chasing a separate download for the newer one. The RTP page turns the published return into a dollar figure per 1,000 spins at the stakes where the sequel is enjoyable.
