How the Game Plays

Oxygen 3 takes place in the submerged futuristic city of Coral Creek, where ruins of an advanced civilization and sunken monorails rest on the ocean floor. The game is played on a 6x7 grid using a cluster pays mechanic, where winning combinations are formed by groups of five or more identical symbols connected horizontally or vertically. Symbols feature various types of coral, colorful fish, and a high-paying octopus. An avalanche mechanic removes winning clusters from the grid, allowing new symbols to drop down and potentially create consecutive wins within the same round.

Free Spins Explained

Landing three or more bonus scatter symbols triggers the Free Drops feature. During this round, all position multipliers generated on the grid become persistent, meaning their values do not reset between spins, allowing them to accumulate and grow for the duration of the bonus. A Super Bonus version is also available, which guarantees persistent multiplier increases and enhanced features to maximize potential.

Oxygen Multipliers & Clam Features

The core mechanic centers on Oxygen Bubble multipliers that appear in empty grid positions after winning symbols are removed. When a new winning cluster lands on a position containing a multiplier, the value doubles, reaching up to 2,048x. The Multiplier Strike feature can randomly add or upgrade multipliers on the grid. Furthermore, special Clam symbols act as modifiers that can collect, multiply, or spread these values across the reels, significantly boosting the payoff of any clusters that pass through them.
