Coin Volcano by 3 Oaks Gaming at 1xBet
Coin Volcano comes from 3 Oaks Gaming and first appeared in August 2023. The studio describes a volcano that erupts multipliers and sets up a coin-collecting round. This is the developer's specification, not a promise about any single account.
1xBet and the demo controls
On 1xBet, the game profile points to the studio build. The demo uses a spin button and a bet selector. Coin Volcano has no skill input, so results are random. Regional access can differ by account, so check your own lobby before playing.
What the developer specification lists
- Bonus game with collect symbol
- Mystery and mystery jackpot symbols
- Grand jackpot x500
- Volcano multipliers feature
- Bonus game and ultra bonus game
These items describe the game's structure. They do not promise a particular outcome in a session. The x500 figure belongs only to the grand jackpot label.
How the bonus game starts
Three symbols on the middle row activate three respins from the bonus game. A sticky coin stays locked until respins trigger, which raises the chance of starting the round. During respins, bonus symbols carry various values and can be collected.
| Feature | What the spec says |
|---|---|
| Bonus trigger | Three symbols on the middle row start three respins |
| Sticky coin | Remains locked until respins trigger |
| Collect symbol | Gathers all current coin values |
| Volcano multipliers | May randomly activate during respins |
| Ultra bonus game | Triggers at random and guarantees volcano multipliers |
The volcano multiplier feature can place one to nine multipliers across the reels. This is a random event inside the respins. The ultra bonus game also triggers at random and guarantees the multiplier feature at the start of the round.
Jackpots and special symbols
The mystery symbol can turn into any symbol except the sticky coin. The mystery jackpot symbol may appear and reveal one of the jackpots. Respins offer a chance to land mini, minor, and major jackpots. Filling the entire grid may potentially award the grand jackpot.
| Item | Specification detail |
|---|---|
| Grand jackpot | Listed at x500 |
| Mini, minor, major | May land during respins |
| Mystery symbol | Can become any symbol except sticky coin |
| Mystery jackpot symbol | May reveal one of the jackpots |
A collect symbol gathers all current coin values on the reels. That is separate from the jackpot symbols. The specification does not attach a probability to any of these events.
The volcano metre
The volcano metre fills with each symbol on an active line. When full, it triggers the bonus. This gives the base game a visible progress marker. The metre is part of the documented design and does not guarantee a bonus within a set number of spins.
| Entry point | Trigger type |
|---|---|
| Bonus game | Three symbols on the middle row |
| Volcano metre | Fills with each symbol on an active line |
| Volcano multipliers | May randomly activate during respins |
| Ultra bonus game | Random trigger, guarantees multiplier feature |
The volcano metre and the three-symbol trigger are two separate routes into the bonus. One fills over play; the other starts from a single row event. Neither changes the random nature of the reels.
Reading the studio page
The developer page at 3oaks.com/game/coin_volcano carries the official artwork and feature text used here. It shows the same bonus, collect, mystery, and multiplier items. Treat that page as the reference for the studio build, not as a record of your account.
Coin Volcano mixes a coin-collection round with random multipliers and several jackpot labels. The rules are set by 3 Oaks Gaming. Availability and any local configuration remain a matter for the 1xBet lobby you use.
