What We Think
The part of Oxygen 2 worth your attention is the Wild Mines. It gives the underwater theme something to do beyond the spin button, and it is where most of your bigger results will come from.
At 94.00% RTP it sits a little below the 96% mark many players use as a reference point. Trying the free Oxygen 2 demo is a low-risk way to judge whether the high-variance swings suit your style before you wager real money at the real money sites with competitive RTP.
What Makes Oxygen 2 Different?
The Wild Mines is the feature that separates it from the rest of ELK Studios' underwater range.
If that style appeals, you can browse the highly rated uk slot sites to find somewhere to play for real money.

How Oxygen 2 Plays
Oxygen 2 is a five-reel slot from ELK Studios. With high volatility, wins land less often but carry more weight, so the bigger moments tend to come from the features rather than the base game.
Stakes run from £0.20 to £100 a spin, so it suits a range of bankrolls.
Oxygen 2 Bonus Features
The features that shape Oxygen 2 are:
- Wild Mines
- Blaster Wilds
- Exploding Wild Mines
Each one feeds into the bonus side of the game, and the Wild Mines in particular is where the 25,000x your stake top win becomes possible. If the bonus round is the draw, it is worth exploring latest free spins no deposit promotions.
Oxygen 2 RTP and Volatility
Oxygen 2 runs at an RTP of 94.00% with High volatility, and the maximum win is 25,000x your stake.
That return sits a little below the 96% reference point, and some operators run lower RTP variants, so check the game menu before playing.
The 25,000x your stake ceiling reflects the high variance: this is a slot that pays through its features rather than steady base-game wins.
Oxygen 2 vs Northern Sky
Oxygen 2 and Northern Sky are worth putting side by side, even though they take different themes, because the RTP, volatility and top win are where your choice really comes down.
| Feature | Oxygen 2 | Northern Sky |
|---|---|---|
| Provider | ELK Studios | Quickspin |
| RTP | 94.00% | 96.57% |
| Volatility | High | High |
| Max Win | 25,000x your stake | 36,000 coins per spin |
| Theme | Cartoon Deep Sea / Underwater Submarine | Nordic wilderness |
If those numbers suit you better, try the Northern Sky demo.
Who Should Play Oxygen 2?
Oxygen 2 is a good fit for:
- Players who enjoy Wild Mines-style features
- Players comfortable with high variance and longer dry spells
- Fans of ELK Studios and the underwater theme
Look elsewhere if you want frequent, low-variance wins. In that case, browse a new online casino uk for a calmer option.
Final Verdict
Oxygen 2 earns a 6.4 from us. The Wild Mines gives it a clear identity, the 94.00% RTP is the main caveat, and the high variance is the thing to weigh before you play.
For an underwater slot with a big top end, it is worth a spin on the demo first. Players who like the theme should also try the Notre-Dame Tales Gigablox demo.
