This cute little reel-based game contains some pretty explosive bonuses, jackpots scattered throughout its 3×3 layout, gorgeous graphics and addictive gameplay that keeps the player in suspense.

General Characteristics

Theme and story

Coin Volcano takes players to places with extreme volcanic conditions, where you have to endure the heat to uncover treasure. This is because the theme of the game is fire and lava, so the situation can get very tense. Imagine spinning the reels while you are just standing on the edge, watching the volcano that is about to erupt.

Visual and Audio Design

Coin Volcano’s visual design is stunning with its gorgeous graphics that do a good job of adapting the volcanic theme. The reel action takes place against the backdrop of a fiery volcano, from which lava continues to flow and smoke billows. The symbols/substrate look like melted coins or any other icon that fits in with this fiery image. Equally complementary is the sound, where dramatic music and sound effects further enhance the experience.

Special symbols

  • Sticky Coin Symbol: this symbol remains on the reels until it activates the bonus feature. It appears only in the main game and increases the chances of activating the Bonus or Ultra Bonus game.
  • Mystery symbols: they can transform into any other symbol except the sticky coin, which adds an element of surprise to the game.
  • Jackpot symbols: these symbols can represent MINI, SMALL or BIG jackpot prizes, offering players plenty of opportunities to win big.

Bonus Features

  • Hold & Win Bonus Game: activated when three symbols fall on the middle reel. Three respins are granted, and with each new sticky symbol the respins reset. The coin value accumulates in the win counter and is paid out at the end of the round.
  • Ultra Bonus Game: an extended version of the bonus game with guaranteed multipliers that is triggered randomly, or players can also buy it. The multipliers can really boost your overall winnings.
  • Mystery symbols, mystery jackpot symbols: these are symbols that transform into other symbols or jackpot prizes to establish different levels of interest and probability of big winnings.
  • Volcano multiplier feature: these can appear randomly on the reels during the bonus game and significantly increase the potential winnings.
