OXYGEN Top Features

Oxygen is a medium/high-volatility slot game by ELK Studios with a relaxed vibe to it. Its colourful six-reel grid sits at the bottom of the ocean, where each spin will to the sound of a cheerful, bubbly soundtrack!

Here are Oxygen’s top features.

Bonus Features

Multipliers are the stars of the Oxygen bonus features show.

When you first land a win, you’ll trigger a multiplier in that position. Those multipliers start from 1x but they'll double consecutively up to 2,048x for every win you score in the same position.

Other multipliers can also be randomly triggered:

  • in the multiplier strike feature, random multipliers fall on the reels
  • when the collector feature is part of a winning cluster, it collects all multiplier values on the grid.
  • the dealer feature multiplies the multiplier values in any V shape area adjacent to it.

The regular wild functions as you'd expect a wild to.

However, the exploding wild removes all symbols in its surrounding X-shaped area if it is part of a winning cluster. In turn, the X-blaster wild will randomly select another wild or pay symbol to substitute all symbols around it, also in an X shape. If it encounters any other X-blaster or exploding wilds, it will trigger those too! The chain effect is a sight to behold!

Lastly, land three scatters and get 10 free spins! If another two or three hit, you’ll get another three or five spins, respectively. Land a persistent multiplier feature in addition to the scatters and you’ll get a guaranteed persistent multiplier feature during this bonus round.

Unique Elements

As with most titles from ELK Studios, Oxygen stands out as an immersive and engaging slot. For instance, while most slots only have one wild, Oxygen has three! Its bonus features are also nothing to scoff at, and it’s got a super bonus game on top of the standard one!

Type of Slot

Oxygen's cluster pays system replaces the winlines typical of most slots. This means that you win by landing at least five matching symbols vertically or horizontally and, after that, the winning symbols will be removed from the grid and new ones will drop to their positions.

Above Average Max Win

Oxygen has a pretty high maximum win. It can produce payouts of up to 25,000x your stake.
