- A great sequel with a few change from Elk Studios
- Oxygen bubbles are a unique and fun feature
- A massive win potential but low RTP as usual
Oxygen 2 slot is a sequel from Elk Studios, bringing you back to the mysterious underwater world. The action unfolds on a 6×7 grid with Dropping Symbols and Cluster Pays mechanics, where forming clusters of at least five matching symbols gives you a win. There are also cascades in play which is nice to see. With slightly higher volatility than the original game and a bit of a redesign, it certainly has a bit more to offer, but doesn’t deviate too much from the original.

Oxygen 2 Slot Bonuses and Features
Oxygen Bubbles & Multiplier Strike. Winning clusters trigger the Avalanche mechanic, where symbols vanish, and new ones cascade down to fill their place. If symbols explode during a spin, they leave behind Oxygen Bubbles—these are key to unlocking multipliers. Each subsequent explosion on the same positions increases the multipliers exponentially, with values maxing out at x2,048. The Multiplier Strike feature randomly adds multipliers to the grid during your spins.
Special Wild Symbols. There are three types of Wild symbols in Oxygen 2:
- Exploding Wilds remove symbols in cone-shaped areas and trigger cascading drops. They also activate hidden Oxygen Bubbles in their range.
- Blaster Wilds target specific symbols and transform surrounding ones into matching symbols or standard Wilds, creating potential for massive cluster payouts.
- The basic Wild substitutes for regular symbols.
Jellyfish & Octopus Features. These can trigger randomly:
- The Jellyfish Feature adds instant multipliers to random positions on the grid, combining with existing multipliers.
- The Octopus Feature places multipliers strategically, then boosts them when they are part of a winsome cluster.
Free Spins and Super Bonus Free Spins. Free Spins are activated when you land three or more Bonus symbols. You start with 10 free spins, where progressive multipliers remain active throughout, until reaching their maximum potential of x2,048. For higher payouts, the Super Bonus Free Spins mode is triggered with four Bonus symbols. This feature integrates all extras, such as persistent Jellyfish and Octopus capabilities.
X-iter Bonus Buy Feature. This is something you’ll see in most Elk Studio slots, allowing you to buy your way into several bonuses depending on where you play the game. These options include higher chances of triggering Special Wilds or jumping straight into Bonus or Super Bonus modes. Prices vary depending on your stake.
Conclusion
Oxygen 2 slot from Elk Studios builds on the success of its predecessor without losing its core charm. By retaining the beloved Cluster Pays and Avalanche mechanics while introducing a few new features, it will certainly please fans of the original. The maximum win potential will surely attract high spenders, but as usual the RTP is low at just 94%, though if you know anything about this developer you will not be surprised and it’s unlikely they will change this anytime soon. I think Oxygen 2 is a worthy addition to ELK Studios’ impressive lineup of slots, and if you want to see what else they have to offer, read our review on Tinkerbot slot here.
