Gameplay in Coin Volcano Video Slot

Gameplay in Coin Volcano begins with selecting a bet amount per spin. The chosen value is adjusted using dedicated controls on the game’s interface.

Each round starts with a single spin, during which both standard coin symbols and special icons may appear. The main goal is to match symbols on a line or activate bonus functions through certain combinations, most commonly across the horizontal middle row.

When a spin is triggered, all reels stop at once. If suitable symbols appear, they lock in place. Landing three or more relevant icons may lead to a series of respins or boost the total payout.

Symbols in Coin Volcano

There are no traditional symbols in Coin Volcano. Instead, the game uses a variety of special icons. The core symbols are regular coins and jackpot coins, which award higher payouts of 10× (Mini), 20× (Minor), or 50× (Major) the bet.

Another group includes Mystery Symbols, which transform into other icons to help form winning combinations, and Sticky Coins, which appear randomly in the base game and stay fixed until the bonus round begins, increasing the chance of triggering it.

Also present are Coin Collect symbols that appear during the bonus and collect all visible coin values and volcano multipliers on the reels. These symbols are added randomly during bonus gameplay.

Bonus Games

Coin Volcano features two main bonus games based on the Hold and Win mechanic:

Hold and Win

This feature activates when three special symbols land on the middle row of the 3x3 grid. The bonus game begins with three respins. Each new symbol that appears locks in place, and the respin count resets to three. The round continues until no respins remain or all nine cells are filled. At the end of the bonus, the values of all collected symbols — including jackpots and multipliers — are summed and awarded as a total win.

Ultra Bonus Game

This expanded version of the standard bonus round can launch at random. Its standout feature is the guaranteed use of the Volcano Multiplier at the start, which significantly boosts win potential.

Fixed Jackpots

The game includes four fixed jackpots: Mini (x10), Minor (x20), Major (x50), and Grand (x500), all of which can be won during the bonus rounds.
