3 Coin Volcanoes by 3 Oaks Gaming on 1xBet
3 Coin Volcanoes comes from 3 Oaks Gaming and appeared in November 2024. The developer describes a 4x3 reel set framed by lava, with five jackpots reachable during play. The layout stays simple. The interest sits in a bonus game where three volcanoes above the reels can wake up and change the round.
How the 3 Oaks Gaming demo works
The official demo runs on a 4x3 grid. Two active lines are documented, which makes this an unusual slot shape rather than a wide payline game. The developer's own page and its specification are the sources for the controls and features described here. A 1xBet account may show a different configuration, so the rules you meet in play are the ones that govern your session.
Symbols and the mystery role
The specification lists MYSTERY and MYSTERY JACKPOT symbols. The mystery symbol transforms into any other symbol, so it can complete a line the base symbols would miss. The mystery jackpot symbol instead reveals one of the available jackpots when it appears. Both are documented as part of the main symbol set, not as a separate mode.
Controls in the demo
The demo exposes the usual spin and bet controls of a 3 Oaks product. Watch the strip above the reels during spins. Bonus symbols landing on an active line ignite green, red and blue fire effects, and those effects wake the three volcanoes. That visual link matters, because the volcano state decides which booster you carry into the bonus game.
1xBet context for the bonus game
On 1xBet the game sits inside the slots catalogue under its own profile. The provider specification is not the selected configuration of every account, so treat the feature list below as the developer's documented version. One regional-access note: some markets restrict or exclude certain titles, and a catalogue entry does not guarantee the game is playable for every account.
Starting the bonus
Four symbols on either of the two active lines trigger three respins from the bonus game. The respins are the core round. Within them, the mini, minor and major jackpots can land. The boost symbol collects all current values on the reels, which is how a respin round can concentrate value rather than scatter it.
Boosters tied to the volcanoes
Once one or more volcanoes are awake, the bonus game begins with matching boosters. Each booster changes the round in a different direction.
| Booster | Documented effect |
|---|---|
| LIFE | Refills the respin counter |
| MULTI | Unleashes multipliers that combine when they land in the same cell |
| GROW | Unlocks two extra rows |
Fire effects stay active during the bonus and may trigger additional boosters. So a round can begin with one volcano awake and gain another partway through. The grow booster expands the grid, and filling that expanded grid while it is active awards the royal jackpot.
Jackpot values in the specification
Two jackpots carry fixed multipliers in the developer specification. Others appear through the bonus round without a stated multiplier there.
| Jackpot | Documented value or trigger |
|---|---|
| Grand | x500 |
| Royal | x2000 |
| Mini, Minor, Major | Can land in the respin round |
Filling the screen may result in the grand jackpot. Filling the expanded grid while grow is active awards the royal jackpot instead. Those are two distinct conditions, so the grid size at the moment of the fill decides which one applies.
The lucky eruption extra
One further path exists. The lucky eruption extra offers a chance to activate the bonus game with a minimum of two boosters. That means a round can start with more of the volcano effects already running, rather than building them one at a time through the base game.
Reading the feature list
The specification names the bonus game with collect symbol, mystery and mystery jackpot symbols, multi volcano, eruption feature, life volcano and grow volcano. Each name maps to something described above. The collect symbol is the boost symbol that gathers current values. The eruption feature covers the ignition of the volcanoes.
- Grid: 4x3 in the main game, expandable by two rows with grow.
- Active lines: two.
- Trigger: four bonus symbols on an active line.
- Respin count: three at the start of the bonus.
- Jackpots named: mini, minor, major, grand, royal.
Do not map the numeric volatility value in the specification to a label. The source gives a number, not a word, and the units and limits should be read as published. Release month is November 2024, which places this title after the earlier 3 Oaks volcano games rather than alongside them.
