About CoinVolcano.boats — Who We Are & How We Test

What this site is

CoinVolcano.boats is a small independent project covering one game in detail: Coin Volcano, the 3×3 Hold & Win pokie by 3 Oaks Gaming. Rather than rehashing press releases, we build interactive tools — a bankroll calculator, a Buy Bonus ROI calculator, and a multiplier-stacking visualiser — so you can see exactly what the game does with your money before you deposit.

We are not a casino and we do not operate the game. Everything here is informational and aimed at Australian players using AUD.

How we research the game

Where our numbers come from

RTP (95.66%), volatility, max win (2,551×) and jackpot values are taken from 3 Oaks Gaming's published paytable and game information screen.
Mechanics (Hold & Win trigger, respin loop, Sticky Coins, Coin Collect, Volcano Multiplier stacking) are documented from the in-game rules and verified in demo play.
Trigger frequency (~30–60 spins) is a community estimate, not an official figure. We label it as an estimate everywhere it appears, because the provider does not publish hit frequency.

Our rule on estimates: if a number isn't officially confirmed, we say so. The calculators let you change the assumptions yourself, so you can stress-test our defaults rather than take them on faith.

Editorial independence & affiliate disclosure

CoinVolcano.boats is funded through affiliate links. If you follow an outbound "Open Coin Volcano" link and later register or deposit at a partner operator, we may earn a commission at no extra cost to you. See our full Terms & affiliate disclosure for detail.

That funding model does not change our numbers. The RTP comparison on our Coin Volcano vs 9 Coins page openly states that 9 Coins has the higher RTP, and our strategy guide states plainly that no strategy beats the house edge. We would rather be useful than flattering.

Play safe
