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 $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.

Oxygen 2 is a solid follow-up to the original. The bonus features are engaging, but I wish the RTP was a bit higher. Still, a great choice for players who love high-risk, high-reward gameplay.
Great slot with fun mechanics, but the volatility is quite high. I had some dry spells before hitting a big win, but when it happens, it's thrilling!
I love the visuals and theme! The sticky multipliers really add to the excitement, and the free spins mode can be super rewarding. Definitely one of my new favorites!
