About the slot
Featuring cluster pays, sticky multipliers, and a variety of exciting bonus features, Oxygen 2 offers an immersive gaming experience filled with vibrant sea creatures and sunken treasures.
Theme and Design
Set in a submerged world of shipwrecks, corals, and marine life, Oxygen 2 presents a visually stunning environment. The 6x7 transparent gaming grid is surrounded by deep-sea elements, where creatures have adapted to human debris. You’ll find crabs using wrenches as claws and snails living in tin cans, adding a creative touch to the oceanic theme. The detailed animations and ambient sound effects further enhance the deep-sea experience.
Gameplay and Features
Oxygen 2 operates on a 6x7 grid, with wins forming through clusters of five or more matching symbols. When a winning cluster is formed, the symbols explode, allowing new symbols to drop in—a mechanic known as the avalanche feature.
Betting Range and RTP
Players can place bets ranging from $0.20 to CA$100 per spin. The game runs on a high-volatility math model with an RTP of 94%.
Symbols and Payouts
Low-paying symbols: Green, orange, and pink floaty shapes.
High-paying symbols: Four distinct sea creatures.
Wild Symbol: Substitutes for any pay symbol and carries the highest payout value when forming winning clusters.
Big Symbols: These come in 2x2, 3x3, or 4x4 sizes and may carry multipliers.
Clusters of 5 symbols offer 0.1x to 1x the bet, while larger clusters (16+ symbols) can reward up to 100x the bet.
