Oxygen Information

The Oxygen slot by ELK Studios submerges beneath the ocean floor, featuring a shipwreck in the background while you spin the reels, accompanied by occasional bubbles on either side of the grid. The title's irony is evident, given the fact that you’re stuck underwater.

The visuals are vibrant and bold, and the game boasts all sorts of features, including multipliers of up to 2,048x, symbol transformations, wilds, a bonus game, and a super bonus game.

Oxygen Gameplay

The Oxygen slot is played on a 6x7 grid and uses the Cluster Pays mechanic. Winning combinations are created by landing 5 or more identical symbols in a cluster. Once a win occurs, the symbols involved are removed, and the remaining ones cascade down until they settle in a new position.

New symbols drop from above to fill any vacant spaces, and this continues until no new winning clusters form. Each winning combination doubles the multiplier value on the symbol positions covered by that particular win.

On the reels, lower-paying symbols consist of differently coloured gems in fishing nets, while higher-paying symbols include various fish and a diving helmet. The diving helmet stands as the biggest paying symbol, rewarding players with between 1x to 100x times their total stake for forming clusters of 5 to 14 or more.

Bonus Rounds in Oxygen

Wilds: The game has 3 types of wilds:

  • Standard Wild: Substitutes for all paying symbols.
  • Exploding Wild: Activates when part of a winning cluster, removing all payout symbols within an X-shaped area above and below itself. Detonates when no more winning combinations appear, triggering all features within the X-Shape area.
  • X-Blaster Wild: Triggers when part of a winning cluster. Selects a random paying symbol or standard Wild, replacing all paying symbols in an X-Shape. Exploding Wilds or X-Blasters transform into standard Wilds.

Multiplier Features: Multipliers play a huge role, particularly in the Oxygen Bubble feature. After each winning combination, the multiplier value on each winning symbol position doubles, reaching a maximum of up to 2,048x. While multiplier values reset between spins, they won’t reset during the Free Drops Bonus Game. Random multiplier features can also activate:

  • Multiplier Strike: Triggered on any symbol drop or free drop, places a random number of multipliers on the grid.
  • Collector: Gathers all multiplier values in view when part of a winning cluster.
  • Dealer: Multiplies all multipliers in the direction of the radar. Activates when part of a winning cluster.

Free Drop Bonus Game: Triggered by Bonus Scatters. All multiplier values remain throughout the bonus round, which begins with 10 free drops. Additional free drops are awarded with 2 or 3 Bonus symbols during the round.

Super Bonus Game: If 3 Bonus Scatters and a persistent multiplier feature are landed, you’ll get 10 super bonus drops. Multipliers persist as in the standard Bonus Game, and at least 1 multiplier feature is guaranteed. Land 2 or 3 Bonus Scatters for 2 or 5 extra free drops.

Big Symbols: During the bonus there is also the chance for Big Symbols to drop, which can come in the form of 2x2, 3x3 or 4x4 sizes.
