Review of the Coin Volcano slot machine from Booongo
Introduction
Coin Volcano from the provider Booongo — this is not just a classic slot machine, but a bright representative of the popular Hold & Win mechanic ("Hold and Win"). Its main feature is the complete absence of base payouts, which makes the game extremely volatile and solely focused on activating the bonus round.
Key Features
- Hold & Win mechanics with fixed jackpots.
- Absence of standard winning combinations in the base game.
- Extreme volatility and high win potential.
- Compact 3x3 grid for intensive gameplay.
Design and atmosphere
Coin Volcano offers a minimalist, yet stylish design. On the background of the image of a volcano, erupting coins, a simple 3x3 grid is placed. The graphics are rendered in bright, contrasting colors, ensuring excellent readability of symbols. The sound accompaniment is unforgettable: deep hits of barabans and the ringing of coins during the bonus creates an atmosphere of anticipation of a big win, not leaving the player.

Payouts for combinations
In the base game, there are no standard payouts for combinations of regular symbols. The only way to win is to activate the bonus function Hold & Win, where coin-symbols carry cash values or jackpots.
Bonus functions and unique mechanics
The basis of the game is the bonus round Hold & Win.
- Activation: the bonus is triggered when three or more special coin-symbols (Bonus Symbols) fall on a single active payout line.
- Mechanics: after activation, all coin-symbols "stick" to their positions, and the player receives 3 respins. With each new spin, new coins may appear, which also stick, and the counter of respins resets to 3.
- Symbols in the bonus: coins may contain:
- Fixed cash amounts (for example, 1x, 2x, 5x, etc. from the stake).
- Jackpots: Mini, Minor, Major, and Grand. To win one of the jackpots, you need to collect three identical jackpot symbols on the grid.
- Special symbols: in some versions of the series, Mystery Symbols may appear, revealing random values, or Coin Collector symbols, collecting values from other coins.
- Completion: the bonus ends when the player runs out of non-paid spins. The total win is accumulated from the sum of all collected coins and jackpots.
Expert opinions and recommendations
Coin Volcano is a slot for patient players, ready for long periods without winning, with a chance for a big win in the bonus. The strategy here is simple: manage your bankroll.
Due to extreme volatility recommended
Set minimum bets to prolong the gaming session and wait for the activation of Hold & Win. Don't expect frequent wins, but significant payouts are the game's mathematics aimed at rarity.
Mathematical model
- The slot has an RTP of 95.66%, which is a standard indicator for modern slot machines.
- Volatility is stated as "above average," but in practice, due to the absence of base payouts, it feels extreme.
- Chances of winning directly depend on the frequency of the bonus function's activation.
Compared to analogs
- Money Train 2 (Relax Gaming): has a similar concept with a focus on bonuses, but has a much more complex mechanism and higher RTP.
- Jammin’ Jars (Push Gaming): also utilizes the 'sticky' mechanics of symbols, but offers base payouts and a different game structure.
Mobile version
Coin Volcano is fully adapted for mobile devices. Thanks to the use of HTML5 technology, the slot correctly displays and works on all modern smartphones and tablets running iOS and Android. The compact 3x3 grid fits perfectly on the phone screen, ensuring a comfortable game anywhere.
