Coin Volcano 2 slot — the fact sheet
A spec-sheet view of Coin Volcano 2: symbols, board, design, math, lineage. The weighing-up lives in the main review ; how a round unfolds in practice lives in the game guide .
Symbols: the same alphabet, a longer sentence
The sequel keeps the series’ radical reduction — reels showing only blanks and coins, no line wins in the base game — and spreads it across a 3x5 board. The coin types carry over intact: cash-value coins holding stake multiples, jackpot coins naming a tier, and mystery symbols that reveal their contents during the bonus. What is new is under the coins rather than among them: designated multiplier cells on the grid that boost whatever coin locks onto them, turning position into a variable the original never had. Payment still happens exclusively in the Hold and Win, entered via bonus symbols; the Ultra Bonus adds a second, richer floor to that feature rather than a separate mechanic.
Design
Visually the sequel runs hotter than the original — deeper reds, more lava movement, a wider crater panorama behind the longer board. The functional design choice worth noting is cell highlighting: multiplier positions glow through the base game, so the geography that will matter in the bonus is visible before it triggers. The eruption remains the signature event, now serving a board with more places for its multipliers to land — and multipliers landing on an occupied cell combine rather than replace.
The math profile
RTP of 95.66%, volatility Medium to high, bets spanning $0.10 – $70, and an advertised cap of 500x — deliberately below the original’s, in exchange for 5 jackpot tiers and denser feature layers. Released August 7, 2025, HTML5 on every platform.
Lineage
The sequel is the series’ “more moving parts” branch: richer than the original , less mechanically radical than 3 Coin Volcanoes with its three specialized volcanoes. Meet it in the free demo first — worth repeating for US readers, since real-money access needs a state-licensed casino in one of eight iGaming states (21+) and 3 Oaks games are scarce even there.
