Oxygen Slot Design
Oxygen has an underwater theme that is displayed very well through the backdrop and symbols. The backdrop sees you underwater, and as a result, the background is a dark, deep, blue colour. There is a black shadow outline of a sunken ship in the distance in front of an underwater cliff. In the foreground, there are very colourful, vibrant coral and plant life. The symbols on the playgrid feature different coloured orbs wrapped in netting and other colourful, animated fish symbols.

Oxygen Slot Bonuses
Oxygen has many unique gameplay mechanics and bonus features, which make this a very interesting slot game. First of all, Oxygen applies a cluster pays mechanic, meaning that for combinations to be made, symbols must touch each other horizontally or vertically. Then, there is also an avalanche feature, which removes symbols involved in combinations and allows new symbols to fall to take their place. Finally, there are also big symbols. Big symbols are essentially symbols that can randomly appear in sizes 2×2, 3×3, and 4×4.
Furthermore there are also some other bonus features included in the base game. There are multipliers behind every position on the playgrid, which are activated through landing combinations. Every combination doubles the multiplier value on the symbol positions covered by the matching combinations. There are also collector multiplier symbols, which, when activated, collect other multipliers to improve their own value and provide multipliers in a V shape from their position. Then there are wild symbols, and Oxygen actually has 3 different wild symbols with these being:
- X-Blaster Wilds – A random payout or wild symbol is selected and replaces all payout symbols in an X-shape.
- Exploding Wild – Removes all payout symbols within an X-shape area above and below itself.
- Wild Symbols – Wild symbols substitute for other base symbols.
On top of all of this, there is also a bonus free spins round, which can be triggered through landing 3 bonus symbols. In the bonus game, all multiplier values are persistent between free drops. If you land 3 more bonus symbols, the game can also be retriggered with a guaranteed persistent bonus multiplier symbol.
