Oxygen 2 Slot

Well, the title of this review signals the follow-up to the successful release of Oxygen by ELK Studios, which dropped into online casinos in 2023. Now, with Oxygen 2, the game takes a more adapted approach. Oxygen was very basic for its time and for the developer. Oxygen 2 is more robust and presents players with more features and thrill. 

For those who missed the original slot, Oxygen is an aquatic-themed casino game. Both the original and this follow-up retain the dynamic seven-row by six-reel layout, which includes all the features you could want, like enlarged symbols, multipliers, and exploding wilds. 

Nothing is quite ordinary; you get innovation, and ELK Studios' biggest compliment is that many developers take its ideas. 

Let’s find out why as we submerge ourselves in this game and bring you the most concise review covering everything from bonuses to settings. The free slots demo is available; create your free Casinos.com account for instant access. 

Roughly 95% of all ELK Studio slots are made with a high volatility program, which is why I ran as soon as I was up on my balance. High-volatility games can be unforgiving, so think strategically. The RTP is always going to be below average and at 94%. This is purely because the maximum payout can be up to $2,500,000!

When you come to play Oxygen 2 for real money, load the game and start by placing your bets. Click on the coin icon, and choose your value to pay per spin from the presets. Bets range from $0.20 to $100.

Once you’re ready to play, press the spin button, and the symbols on the rows and reels will drop off the grid. New symbols will enter into the game from above. This action is your bet played out, and winning comes by forming clusters of matching symbols. You need to have a cluster of five or more symbols. The bigger the cluster, the bigger the prize. 

When you win, the Avalanche feature activates. All winning symbols disappear, those above fall into the vacated space, and new symbols enter the game. This action does not take any funds from your balance. In fact, it’s a chance for you to land new clusters, which will again activate the Avalanche feature for an indefinite amount of time until no cluster is formed. 

Oxygen 2 is laced with in-play features, it’s an expectation of any ELK Studios slot, and this one does not disappoint. 

Oxygen 2 by ELK Studios is an improvement on the first game. It looks the same, but big things lurk in its depth. The gameplay can be hard because of its high volatility, and it can be long because of the Avalanche feature. Patience is needed for a game like this.
