Game information and features
Before diving into the blazing action of this slot machine, take the time to familiarise yourself with its characteristics.
Discover what makes this game a unique experience in the world of online casinos.
General game overview
Created by Booongo Gaming (now 3 Oaks Gaming), this slot machine has carved out a prime spot in the online casino market.
Its compact 3x3 reel format with several active paylines offers a gaming experience that is both simple, intuitive and immersive.
This streamlined format also makes it highly accessible across mobile, desktop and tablet. Regardless of the device used, the experience remains smooth.
Not forgetting the volcanic theme that gives this slot its charm, reflected in its specific graphics and sound design.
Hold and Win: focus on the game's main feature
The Hold and Win mechanic is based on the accumulation of special symbols representing blazing coins. When 3 identical symbols appear on the central line, the bonus is activated.
During this phase, the coins obtained remain fixed and you receive 3 free spins. During these spins (known as the bonus game), any new element that appears will also stay in place and reset the number of re-spins back to 3 — which, as you'll have understood, increases both your winnings and your chances of winning the jackpot.
The jackpot itself is won by successfully lining up 9 identical elements on the reels, awarding 500x your bet.
Added to this is the volcano multipliers feature, which triggers randomly during these phases and increases the multipliers on randomly selected tiles, as well as the possibility of triggering (also randomly) the ultra bonus game (a bonus game with increased chances of triggering the volcano multipliers feature).
Coin Volcano in detail
Now that you know the basics, we can push the analysis of this explosive slot machine further.
Symbols and paylines
To fully understand the mechanics of this casino game, you naturally need to look at its symbols.
The base elements are the golden coins, which award amounts linked to your bet multiplied between 1x and 4x.
Next come the sticky coins — red coins offering a multiplier between 5x and 9x. Their distinctive feature: they remain fixed until the next bonus is triggered.
Please note: if you change your bet, they disappear.
Next are the mini 10x, minor 20x and major 50x symbols, which award the corresponding multiplier if they appear on a winning line.
From time to time, you'll also see a molten lava ball appear with the inscription Mystery or Mystery Jackpot. These are wild symbols that transform into any other symbol (except sticky coins).
Worth noting: the Mystery Jackpot can only transform into a mini, minor or major coin.
Not forgetting the fire whirl, which is the coin collect symbol. In other words: upon appearing, it immediately collects all available rewards (coins and multipliers).
Bonus purchase
We've already covered all the features of this casino game.
But we missed one important one: the ability to purchase the desired bonus directly.
It will cost you 30 times your bet for the bonus game and 75 times your bet for the ultra bonus game.
The goal is to avoid waiting for these phases to trigger naturally in the hope of landing the coveted jackpot.
RTP and volatility
To be thorough, it seems important to mention the RTP and volatility of this casino game.
The Return To Playe is approximately 95.6% — slightly below the slots industry average of 96%.
If you're new to the casino world, this theoretical figure gives you a useful indication of the total amount of your bets you can expect to recover over the long term.
For example: on Coin Volcano, you can expect to recover 95.6% of your bets over time.
As forvolatility, as with most slot machines, we're looking at medium to high volatility.
This means wins will be rare, but potentially very rewarding.
Worth knowing: the maximum winning potential can reach up to 2,551 times your initial bet.
