Coin Volcano bonus breakdown: original vs Coin Volcano 2
The Hold and Win itself takes three sentences to describe. The useful questions are what each game’s bonus pays and what direct access costs: those two numbers, more than the feature list, decide which game fits your bankroll.
The shared engine: Hold and Win with resetting re-spins
Both games trigger on bonus symbols across the middle row: three on the original’s 3x3, a full middle row on the sequel’s 3x5. Coins that land lock in place, the counter starts at 3 re-spins, and each new symbol resets it to 3, so a bonus stays alive as long as coins keep arriving. In both, the Volcano Multiplier feature can trigger during the re-spins and drop up to nine multipliers, and the Ultra Bonus Game triggers at random with the multipliers guaranteed.
Where they split: jackpots and ceilings
| Element | Coin Volcano | Coin Volcano 2 |
|---|---|---|
| Trigger | 3 bonus symbols on the middle row | Middle row filled with bonus symbols |
| Jackpot tiers | Mini 10x, Minor 20x, Major 50x, Grand 500x-2,500x (may vary by casino version) | Mini 10x, Minor 20x, Major 50x, Grand 500x (may vary by casino version) (Grand fills all 15 positions) |
| Extra layer | Ultra Bonus Game | Ultra Bonus Game, Boost Bonus Game via Buy Bonus |
| Ceiling | Max win 2,551x | Top jackpot 500x |
| Multipliers | One to nine volcano multipliers | Up to nine; multipliers on the same cell combine |
Read it as shapes. The original is a peak game: value concentrates in the Grand and the 2,551x advertised max win. The sequel is a layers game: the jackpot ladder is the same, but stacking multipliers and the Boost Bonus add ways to build a round rather than a higher jackpot.
Bonus Buy: the recorded prices
Where offered, the original sells the Bonus Game at 30x the stake and the Ultra Bonus Game at 75x. The sequel asks 50x, 100x for the Ultra, and 300x for the Boost Bonus Game in the regions that sell it. First, check the price shown in your version before comparing anything. Second, paying 50x against a 500x top jackpot (the sequel) is a tighter proposition than the same price against 2,551x, so run that arithmetic before you click. US note: state-licensed markets often strip Bonus Buy from approved builds, so a legal lobby without it is normal.
Matching the bonus to your bankroll
- Small bankroll, long sessions: the original at $0.10. Let the bonus trigger naturally and skip the Bonus Buy math.
- Medium bankroll, likes busier rounds: the sequel, where multipliers stack on the wider grid.
- Peak hunter: the original, accepting longer dry stretches between triggers.
- Either way: run the free demo first; the full spec sheets are in the Coin Volcano review .
