Oxygen 2 Slot Review
Players find themselves back in the underwater realm of Coral Creek in ELK Studios‘ latest release, Oxygen 2!
After catching our breath from the last underwater adventure we took with ELK Studios, we’re having to hold our breath once more as we dive back into the action in the latest Oxygen instalment.
Multipliers worth up to x2,048 make a comeback, with new and refreshing twists and turns in the form of features around every corner. Join us as we inhabit the colourful world of Coral Creek and try our luck against Exploding and Blaster Wilds!
Base Game & Features
Featuring 6 reels, 7 rows, and a Cluster Pays mechanic, Oxygen 2 creates winning combinations when 5-16+ matching symbols land anywhere on the grid, either Horizontally or Vertically. Players can choose between a variety of betting options, from £.€0.20 to £.€100 per spin.
This game has 4 High-paying and 3 Low-paying symbols, each producing payouts between 0.1x and 100x your bet. Each winning cluster is subject to removal via an Avalanche Feature, enabling new symbols to drop in from above to create or enhance additional wins on the grid.
During gameplay, any of the 7 paytable symbols can appear as Big Symbols, in sizes 2×2, 3×3, and 4×4. Lastly, Wilds substitute for all paytable symbols.
Other areas of note are the remaining statistics, including an overall RTP of 94%, a High Volatility rating, and a generous max win cap of 25,000x your bet.
Oxygen Bubbles
The first time a winning cluster explodes, it activates a special Oxygen Bubble. Each new winning cluster to explode on an active bubble position will Double the Multiplier value. Oxygen Bubbles have a starting Multiplier of x1, up to a maximum of x2,048.
Oxygen Bubbles are not affected by the Avalanche Feature and remain in play until the end of a game round. In Free Spins, Multipliers and active Oxygen Bubbles are persistent throughout.
Multiplier Strike
The Multiplier Strike feature positions a random number of Multipliers on the grid. Please note, that this feature can trigger during the base game and Free Spins mode.
Jellyfish and Octopus Features
Randomly, when 1 or more Jellyfish symbols arrive carrying a Multiplier, the Jellyfish feature is triggered.
Once active, each jellyfish will stop at random symbol positions, adding the carried Multiplier to their positions. If there is already a Multiplier in this position, the existing Multiplier will be added to the jellyfish multiplier and applied.
In addition to Jellyfish symbols, Oxygen 2 is also equipped with special Octopus symbols that appear on the grid at random. When an Octopus appears, it will place itself behind a random symbol position.
The Octopus Feature is triggered when a winning cluster occurs on the symbol position with the octopus. Once active, the Octopus will add a random selection of available Multipliers outside of the winning cluster to the win, increasing the Win Multiplier.
Exploding Wilds
When an Exploding Wild is part of a winning cluster, it will activate a special Explode Feature. Once active, it removes all payout symbols within a two-cone-shaped area facing up, down, left, or right.
This feature activates when no more winning clusters are available on the grid. Additional exploding wilds and blaster wilds within this area will also be activated. Alternatively, Super Exploding Wilds will trigger all inactive Oxygen Bubbles behind the exploded symbols.
Blaster Wilds
Special Blaster Wilds activate when they are part of a winning cluster during a spin. Once active, the blaster wild selects a random symbol or Wild, causing the blaster wild to explode and replace all paying symbols within an X or Plus-shaped pattern.
Any exploding wilds or blaster wilds caught in the crossfire will be activated. Symbols affected by multiple Blaster Wild patterns will transform into regular Wild symbols.

Our Verdict
Oxygen 2 from ELK Studios adopts a sense of peace and tranquillity through its underwater theme, as did the first Oxygen release, but don’t mistake its placid nature as boring or tame. In fact, it’s quite the opposite.
What made Oxygen so great and impressionable has found its way into the sequel, while adopting new and refreshing material that will certainly appeal to ELK Studios’ fans everywhere.
Exploding and Blaster Wilds, found in the original, clear a path for new wins and enhanced Multipliers in a single spin, now complimented by nifty Jellyfish and Octopus features.
In the first Oxygen, players faced quite a challenge when building big Multipliers on the grid, but thanks to the colourful Jellyfish symbols here, it’s not quite as daunting as it once was. The challenge you now face is triggering a win on the Octopus position to activate its feature.
You may have noticed that ELK Studios has stripped Oxygen 2 of Persistent Multipliers in the base game. It’s an unfortunate move from ELK, but we’re lucky enough to have multiple features, new and old, to contend with.
If you’re here for the statistics, you’ll find no differences between the two. We would usually say how disappointed we are to see this, but how can you be disappointed at a hefty 25,000x max win cap?
*Oxygen 2 will be available to play at Best Casino Sites from the 4th March 2025
