Oxygen Review
We all need oxygen to survive, and it’s easy to forget that this also goes for subsea creatures. You get to meet some nasty-looking deep water creatures in ELK’s Oxygen slot, and the transparent 6x7 grid is set against a shipwreck in the background. Winning clusters are removed and this upgrades the relevant positions with oxygen bubble multipliers. These are position multipliers that double per subsequent win they partake in, and this is overall a feature-rich game with 2 bonus round tiers.
It seems like ELK has been inspired by Sugar Rush when it comes to the doubling position multiplier system, but they have added enough new tweaks and features to the mix to escape the copycat stamp. You get big symbols, 2 special wild modifiers, and the doubling multiplier positions never reset in either of the bonus rounds. You can even get different multiplier features, and at least one is persistently active in the top-tier Super free spins round. The 25,000x potential is significantly beefed up as well, but you get the below-par 94 % RTP that ELK seems to favor for many of their games.
ELK Studios - Slot Developer
ELK Studios - is a reputable Swedish game provider that’s been in the game since 2012. They release high-quality slot games regularly, and they are well-known for their popular Toros and Nitropolis series. ELK has many popular games out there by now, but they tend to go with a below-average RTP for many of them.

Slot Theme And Storyline
We have seen better visuals from ELK Studios, to be honest, but Oxygen is still a solid subsea release for sure. You get colorful fish symbols of the exotic kind on the transparent grid, and the soundtrack is pleasant enough as well. Nothing too special to see here when it comes to the theme, but it certainly gets the job done.
Oxygen RTP, Volatility, And Max Win
The Oxygen RTP of 94 % is well below the industry average, but typical for ELK these days. There are no RTP ranges to worry about at least, and this is a medium to high volatility installment that scores 7 out of 10 on ELK’s volatility scale.
The Oxygen max win is 25,000x your stake, which is well above average according to our stats.Oxygen Slot - Reels ScreenOxygen Rules And Gameplay
You can play with bet levels between €0.2 and €100 per spin in Oxygen slot, which is a decent bet range. You win by landing 5 to 14+ matching symbols in a cluster anywhere on the 6x7-sized grid, and Wild symbols step in for any pay symbol to help complete or improve cluster wins. There are several different special wilds, as we shall see below, and you get an Avalanche mechanic going in all stages.
Symbols And Paytable
Symbols | Bet Multiplier Values |
---|---|
Octopus in Diving Helmet | 5 to 14+ = 1x to 100x |
Pink Fish | 5 to 14+ = 0.5x to 50x |
Orange Fish | 5 to 14+ = 0.4x to 30x |
Green Fish | 5 to 14+ = 0.3x to 25x |
Pink Stone | 5 to 14+ = 0.2x to 20x |
Orange Stone | 5 to 14+ = 0.15x to 15x |
Green Stone | 5 to 14+ = 0.1x to 10x |

Oxygen Bonuses And Special Features
The doubling multiplier positions take center stage in Oxygen slot, and you get plenty of additional features that can help you out in different ways as well. Let’s dive in to take a closer look!
Avalanche Wins & Big Symbols
The Avalanche mechanic removes all winning symbols from the grid, and this allows for new and existing symbols to drop down and fill the empty positions. This process repeats to give you indefinite winning streaks as long as new winning clusters are formed per drop. You can land big symbols in sizes up to 4x4 at random times.
Special Modifier Wilds
You get the regular wild that steps in for any pay symbol to help complete wins, but there are also 2 Special Wild in Oxygen slot. The Exploding Wild triggers when part of a win, and it explodes at the end of the Avalanche sequence. This explosion removes symbols in an X-shaped area around the Exploding Wild, and the X-Blaster Wild works similarly.
However, the blast of the X-Blaster replaces all symbols with a randomly selected symbol (pay symbol or wild) in an X-shape. Multiple X-blasts turn symbols into wilds each time.Doubling Position Multipliers
Winning positions are upgraded with an x1 multiplier bubble on the first win, and the position multiplier doubles per consecutive win on the same position after that. The position multiplier can double its way up to x2,048 at best, and all multiplier bubbles reset between base game spins. The multipliers do not reset in either of the bonus rounds.
Multiplier Features
You can also trigger multiplier features at random times, and these work as follows:
- The Multiplier Strike - adds a random amount of multipliers to the grid, and it can happen in the middle of an avalanche drop or on the initial spin.
- The Collector - absorbs all multiplier values in view to its own position. This feature can only trigger when the collector is part of a win, and it can be persistent.
- The Dealer - multiplies all multipliers in at least one adjacent area vertically or horizontally in V-shapes, and the multiplier boost is at least x2. This can only trigger when the dealer is part of a win, and it can be persistent.
Oxygen Free Spins
The Bonus Round triggers from 3 scatter symbols in view, and this gives you 10 free spins in the bonus game that follows.
All multiplier positions are carried over into the bonus round, and the multiplier positions only keep growing without ever resetting for the duration of the feature. You win +3 or +5 extra spins from 2 or 3 scatters in view, respectively.Oxygen Super Free Spins
The Super version of the bonus round triggers from 3 scatters in view, as well as a persistent multiplier feature on the triggering spin. You get non-resetting multiplier positions during the super free spins round as well, and also at least one persistent multiplier feature that’s active on every spin. You win +3 or +5 extra spins from landing 2 or 3 scatters, respectively.
Oxygen Bonus Buy (not UK)
The X-iter feature/bonus buy menu is available in some jurisdictions, and it comes with the following 5 options:
- Bonus Hunt - pay 3x the stake per spin to be 3x more likely to trigger a bonus round.
- Multiplier Strike - pay 10x the stake to get a guaranteed multiplier strike feature.
- Persistent Multiplier - pay 25x the stake to get a guaranteed multiplier feature that is persistent.
- Bonus Round - pay 100x the stake to get the regular free spins feature.
- Super Bonus Round - pay 500x the stake to get the super version.
The 200 Spins Oxygen Online Slot Experience
You get a decent taste of the base game, and then we purchase and trigger the Super Bonus Round at 0:43 into the 3:40-minute highlights video. We got a persistent x2 dealer multiplier for the feature, and you can see for yourself how we fared by hitting the play button below.
Review Summary And Verdict
We are happy that ELK decided to go with a theme that’s pretty far from the sugar-laden source of inspiration, Sugar Rush, otherwise, the two games would’ve been too similar. Granted, ELK has beefed up the math model significantly in Oxygen, and they have added more elements to mix up the gameplay. You can land big symbols, for example, and the special wilds are not only cool to look at, but they can be quite effective in prolonging your winning streaks as well.
Still, the position multiplier system steals the show in this game, and the multiplier features add a dash of MT2 to the mix as well.
Getting persistent multiplier features can do serious damage, and not least in the super version of the bonus round. However, getting massive multiplier positions that just sit there can be frustrating, as there is no guarantee that multipliers will connect with a win. The 25,000x potential is 5x what you get in Sugar Rush, which is hard to complain about. Still, you get that pesky 94 % RTP that’s typical for ELK these days, and it might be a deal-breaker for some players.Pros And Cons Of Oxygen Online Slot

Strategy And Tips For Winning
Nobody can promise you an Oxygen slot strategy that will work in your favor all the time, since all online slot games are random. However, we have been experimenting with a strategy just for fun lately, and it’s really simple. You try to guess when the next bonus round triggers, and you increase the bet level when you feel that it’s just around the corner. This may help land you bigger wins in the feature, but there is no guarantee.
