Coin Volcano vs Coin Volcano 2: bonus rounds and Bonus Buy

This guide compares what the Coin Volcano and Coin Volcano 2 bonuses pay and what they cost when you buy direct access: the figures that decide which game to pick.

The shared mechanic: Hold and Win with re-spins

In both games, bonus symbols on the middle row trigger the bonus (three on the original’s 3x3 grid, a full middle row on the sequel’s 3x5): landed coins lock, the counter starts at 3 re-spins, and each new coin resets it to 3. The round ends with a full grid or an empty counter. The Volcano Multiplier feature places up to nine multipliers during the round, and the Ultra Bonus Game, triggered at random, guarantees them in both games.

What differs: tiers and ceilings

Element	Coin Volcano	Coin Volcano 2
Trigger	3 bonus symbols on the middle row (3x3)	A full middle row of bonus symbols (3x5)
Jackpot tiers	Mini 10x, Minor 20x, Major 50x, Grand 500x-2,500x (may vary by casino version)	4 tiers, Mini 10x, Minor 20x, Major 50x, Grand 500x (may vary by casino version)
Extra layer	Ultra Bonus Game	Ultra Bonus Game, Boost Bonus Game (Buy Bonus, select regions)
Top figure	2,551x max win	500x top jackpot
Multipliers	One to nine volcano multipliers	Up to nine, combining on the same cell; x5 start in Boost

In short, the original is a “peak” game: the Grand Jackpot and the 2,551x max win concentrate the value. The sequel is a “layers” game: stacking multipliers and the Boost Bonus add texture to a round whose top jackpot stays at 500x.

Bonus Buy: the recorded prices

Where the operator offers it, buying straight into the bonus costs 30x the bet (Bonus Game) or 75x (Ultra Bonus Game) on Coin Volcano, and 50x (Bonus Game), 100x (Ultra) or 300x (Boost, select regions only) on Coin Volcano 2. Two consequences: first, check the price shown in your version before comparing; second, paying 50x or more for a game whose top jackpot is 500x (the sequel) leaves much less room than on the original, so run the numbers before clicking. In Canadian regulated lobbies the feature may be absent altogether; whether it appears is up to the operator, not the game.

Play with a bonus

Choosing by budget

Small budget, long sessions: the original at minimum bet ($0.10). The bonus triggers naturally, with no Bonus Buy needed.
Medium budget, taste for busier bonus rounds: the sequel, where stacking multipliers keep rounds moving.
Peak chaser: the original, accepting longer dry stretches.
Either way: try the demo first; the full reviews have the complete spec sheets.

Bonuses described here are game mechanics, not win promises; RTP and jackpot values vary by casino version. Play only if you are of legal age: 19+ in most provinces, 18+ in Quebec, Alberta and Manitoba.

Frequently Asked Questions

How does the bonus trigger in Coin Volcano?

Three bonus symbols on the middle row start the Hold and Win (a full Volcano Metre does too): landed coins lock in place, you begin with 3 re-spins, and every new coin resets the counter to 3. The round ends when the grid is full or the counter hits zero. There is no other way to win: the base game itself never pays.

How much does the Bonus Buy cost?

It depends on the game. Coin Volcano charges 30x the bet for the Bonus Game and 75x for the Ultra Bonus Game. Coin Volcano 2 charges 50x for the Bonus Game, 100x for the Ultra Bonus Game and 300x for the Boost Bonus Game, which is sold only in select regions. The exact price displays in-game. Not every operator offers Bonus Buy, and regulated Canadian lobbies in particular may ship versions without it.

Do Coin Volcano and Coin Volcano 2 pay the same bonus?

No. Both have four fixed jackpots (Mini, Minor, Major, Grand). The original advertises a 2,551x max win; the sequel’s top jackpot is 500x, with volcano multipliers that combine on the same cell and a Boost Bonus in select regions. In practice, the original gives rarer, taller peaks and the sequel busier, more modest rounds.
