1. Let the total budget set the bet
The studio has not published a volatility rating, so a stake should come from the amount you can comfortably lose rather than from any expectation of how the game behaves.

3 Coin Volcanoes strategies
5 ways to play 3 Coin Volcanoes with a plan. RTP: not published; volatility: not published; max win: not published.
2. Fix a loss cap and a clock
A bonus that can grow, refill and stack boosters is easy to get absorbed in. A pre-set spending limit and a time limit keep the session within bounds.
3. Learn the three boosters first
Life, Multi and Grow do very different jobs. Knowing which one refills respins and which one enlarges the grid makes the bonus easier to follow.
4. Remember that fire effects are not promises
Seeing a volcano light up signals that a booster is on the way, not that the round will pay well. A booster can still finish a bonus with little to show.
5. Do not chase the Royal
The x2000 requires a filled, expanded grid and no frequency for it has been disclosed. Increasing stakes in pursuit of it turns a feature into a reason to overspend.
