Oxygen 2 comes to us from Elk Studios, themed around aquatic. It runs on 6 reels and a familiar payline structure with a high volatility profile, and a return-to-player rate of 94%.
Where Oxygen 2 earns its keep is the feature set. Look out for scatter symbols that unlock free spins and extra bonus rounds. The high volatility means patience is rewarded — expect quiet spells broken by bigger hits. All told, it's a serviceable entry in the Elk Studios catalogue.
The RTP of 94% is below the industry average of ~96%. This is common for older slots or those with special features. The lower RTP may be offset by unique mechanics or higher maximum win potential.
High volatility means longer gaps between wins, but when wins do land, they can be significantly larger. A bigger bankroll and patience are recommended for this type of slot.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
Oxygen 2 features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
