Four slots from 3 Oaks Gaming now share the volcano theme, released between August 2023 and January 2026. They look related, yet the details differ enough that it is easy to attribute a feature to the wrong title. This comparison puts the four side by side and relies only on what the studio has published. Anything the studio has left out, such as return figures or bet limits, is simply absent here.
Grid layouts
- Coin Volcano (August 2023) is played on a compact 3x3 grid.
- 3 Coin Volcanoes (November 2024) uses a 4x3 layout, and the Grow booster can add two more rows.
- Coin Volcano 2 (August 2025) moves to larger 3x5 reels.
- 3 Super Coin Volcanoes (January 2026) returns to 4x3 and, like its predecessor, can be enlarged by two rows through Grow.
Jackpot ladders
Mini, Minor and Major prizes appear in every game, and each slot lists a Grand jackpot worth x500, awarded when the whole playing area is filled. Only the two games built around three volcanoes add a higher tier: a Royal jackpot of x2000 that can be won by filling the enlarged grid while Grow is active. These multiples describe the jackpots themselves, not an overall ceiling for a round.
Ways into the bonus
The first game wants three symbols on its middle row, and the sequel with 3x5 reels asks for that row to be filled completely; both then grant three respins. In 3 Coin Volcanoes the trigger is four symbols on either of two active lines, which also awaken the volcanoes through green, red and blue fire. 3 Super Coin Volcanoes uses four symbols on an active line to launch a Hold and Win bonus, and a Super Wheel spins beforehand to hand out an enhancement. Lucky Eruption, present in both three-volcano games, can start the bonus with at least two boosters or features already running.
What sets each game apart
The original has the Volcano Metre and a sticky coin that stays locked until respins begin. The sequel keeps the sticky coin and adds a Boost Bonus Game, reachable only through a buy option in select regions. The third game relies on the Life, Multi and Grow boosters, while the fourth lets the Super Wheel awaken a Gold Volcano with bigger multipliers.
How to use the comparison
Choosing between these slots is a matter of taste: a smaller grid with a simple trigger, or a larger layout with several layered features. None of them can be influenced by skill, so set a budget before you start and read the in-game rules.
