During the past few years, we have tested many amazing online games designed by ELK Studios casino software and it seems that the time has finally come to test out another online game from their library of online games. 

Oxygen is a sea-themed online video slot played on a large 6×7 grid with a cluster pays system. Moreover, when it comes to special features, our readers should know that this online game comes with Wilds, cascading reels, Free Spins and multipliers. 

Let’s see what this is all about, shall we? 

Visuals and Symbols

As far as visuals are concerned, it can freely be stated that this online game doesn’t offer anything innovative at all. The action takes place at a sea bottom while various theme-matching icons are dominating the paytable. 

3 crystals are the lowest-awarding symbols in the game, while 3 fish and a diving mask are the most lucrative symbols here. Also, keep in mind that there are several different Wild symbols, each with its own unique bonus feature and scatters responsible for the activation of the Free Spins bonus feature. 

Betting and Extras

As we already stated, this online game comes with a large 6×7 grid and a cluster pays system. To form a winning combo, punters will need to match at least 5 or more identical icons either horizontally or vertically. 

The cheapest available spin costs 0.20 credits while the most expensive one reaches 100 credits per spin. 

The top payout of 25000x the bet is paired with the theoretical return to player (RTP) of 94%which is far below the current average and represents the game’s main drawback. 

On the positive side, this high-volatility online game offers tons of different bonus features. Shall we take a closer look at them?

When it comes to Wild symbolsthis online title comes with 3 different such symbols – regular Wilds, X-blaster Wilds and Exploding Wilds.

3 bonus symbols (chests) will activate the Free Spins bonus feature where you will benefit from a number of freebies and various multipliers. 

Furthermore, there’s the Cascading Reels/Avalanche bonus feature that will remove all winning symbols from the reels and replace them with new ones. 

In addition, all punters who decide to give these reels a spin can count on increasing multipliers and large 2×2, 3×3 or 4×4 symbols. 

Our Thoughts

Oxygen might be the perfect choice for all those punters who prefer more complex online games with outstanding top payout potential. Even though it doesn’t shine in terms of odds, it definitely has a lot of potential.
