Oxygen 2 Slot Review
Dive into a cartoon-inspired underwater adventure with the Oxygen 2 slot from ELK Studios.
Played on a 6x7 grid, this game features quirky aquatic creatures and colorful floats that pay out whenever at least five matching symbols land anywhere on the reels.
Each win activates the Avalanche mechanic, removing winning symbols and dropping new ones into place for potential chain reactions.
Oxygen bubbles can appear in empty spots, carrying multipliers that grow with consecutive wins, reaching up to 2,048x.
Jellyfish can randomly increase these multipliers, while sea mines act as wild symbols, spreading more wilds across the grid. Oversized symbols covering up to 4x4 spaces also boost winning chances.
Free spins take the excitement deeper, with persistent multipliers that don’t reset between Avalanches.
In the upgraded Super Free Spins round, jellyfish multiply payouts even further. The game is highly volatile, offering a maximum win of 25,000x the stake, though its RTP of 94.00% is lower than many competing slots.
How to Play Oxygen 2
The game is set around a sunken submarine, with comical deep-sea characters such as a crab wielding a wrench, a snail carrying a tin can, and a grumpy pink fish with a valve on its back.
You’ll also find fishing floats, octopus, jellyfish, and explosive mines.
You can play Oxygen 2 on desktop and mobile (iOS, Android, and Windows) with bets ranging from 0.20 to 100.00.
