Coin Volcano 2 at 1xBet: 3 Oaks Gaming's Molten Sequel
Coin Volcano 2 is a 3 Oaks Gaming slot with a documented release month of August 2025. It is the larger-format follow-up to the original Coin Volcano, now built on 3x5 molten reels.
How the 1xBet Version Is Set Up
The developer specification describes Coin Volcano 2 as a bonus-led game rather than a standard line slot. It lists a Bonus Game with Collect Symbol, Mystery and Mystery Jackpot symbols, a Volcano Multipliers feature, and fixed jackpots.
One regional note: the provider specification is not the selected configuration of every 1xBet account, and the Buy Bonus option is available only in select regions.
Players venture into the heart of a blazing volcano in this lava-themed sequel, where the iconic gameplay returns with richer mechanics.

Demo Controls From the 3 Oaks Gaming Build
The studio demo shows the standard controls for this game: spin, bet adjustment, and the Buy Bonus entry point where it is offered. The demo also presents the paytable and the rules panel.
Players can inspect symbol values and bonus instructions before risking anything. Nothing in the documented demo suggests a timing or skill edge; the results are driven by the game's random engine.

The Bonus Game and How It Starts
The trigger is positional rather than line-based. Filling the middle row with symbols triggers three respins in the Bonus Game.
During the respins, Coin Bonus symbols can land with various values. Those values may include the fixed Mini, Minor and Major jackpots.
Sticky Coin symbols stay on the reels until the bonus is triggered. Once it starts, those held coins contribute to the running symbol collection.
- Trigger: fill the middle row.
- Initial award: three respins.
- Sticky coins: remain until the bonus triggers.
- Coin Bonus symbols: carry values and can include Mini, Minor or Major jackpots.
- Collect Symbol: gathers all current symbol values.
- Full board: may award the GRAND JACKPOT, listed as X500.
Mystery and Jackpot Symbols
Two special symbols add unpredictability. The Mystery Jackpot symbol can reveal a jackpot prize when it resolves.
The Mystery symbol may transform into a Bonus or a Jackpot symbol. Neither is a guaranteed route to a specific payout.
| Symbol | Documented behaviour |
|---|---|
| Mystery Jackpot Symbol | Can reveal a jackpot prize. |
| Mystery Symbol | May transform into a Bonus or Jackpot symbol. |
| Collect Symbol | Gathers all current symbol values. |
| Sticky Coin | Stays on the reels until the bonus is triggered. |
| Coin Bonus Symbol | Carries a value; may include Mini, Minor or Major jackpot. |
Volcano Multipliers and the Three Bonus Modes
The Volcano Multiplier feature can erupt at any moment. When it does, it drops up to nine multipliers onto the reels.
If several multipliers land on the same spot, they combine their values. That combining rule applies wherever multipliers overlap on the grid.
Three bonus modes are documented, and they differ in how multipliers are handled.
- Bonus Game: the base respin mode with three respins and sticky coins.
- Ultra Bonus Game: can trigger at random, with guaranteed Volcano Multipliers.
- Boost Bonus Game: multipliers are guaranteed and start at an increased x5 value; accessible only via the Buy Bonus option in select regions.
| Mode | Multiplier behaviour | Access |
|---|---|---|
| Bonus Game | Volcano Multipliers can erupt during play. | Triggered by filling the middle row |
| Ultra Bonus Game | Guaranteed Volcano Multipliers. | Can trigger at random |
| Boost Bonus Game | Guaranteed; multipliers start at x5. | Buy Bonus only, in select regions |
Because the Boost mode begins at x5 and guarantees multipliers, its arithmetic is easier to follow than the base game. The base Bonus Game still depends on which symbols land during the respins.
The fixed jackpot structure gives players a clear reference point. Mini, Minor and Major are documented as fixed values inside the Coin Bonus symbols, while the Grand is tied to filling all reel positions.
These jackpots are not progressive prizes. They are fixed amounts described in the specification, with the Grand listed as X500.
Anyone comparing this sequel with the original should note the layout change. Coin Volcano 2 uses larger 3x5 reels, while the documented features carry over the collect-style bonus format.
