Oxygen Features

Oxygen is the latest in a long line of modern grid slots and therefore abides by the Cluster Pays system. In this game, you'll need a group of five matching symbols to land anywhere on the reels but they must be touching horizontally or vertically. 

The lowest-paying symbols are the three coloured gems and you'll need quite a lot of these to see any profit from your stake; 14 or more will do the trick. Moving up the ranks, we find 3 ugly-looking fish and a diver's helmet in which an octopus is hiding. This final symbol can produce up to 100x for 14+ matching symbols. There are also big symbols available with a 4x4 giant symbol being the biggest that can land. The beauty of these is that you are already on your way to a fabulous win and if they connect with other matching symbols, then that win just gets better.

Winning symbols are removed, as is the tradition with the Avalanche after a Cluster Pays combo and new symbols will drop into place. The excitement starts to pick up at this point as multiplier spaces are left behind when winning symbols disappear. Land another win on one of these places during the same winning sequence and that multiplier keeps on doubling.

Multiplier Modifiers & Bonuses

Multipliers can receive some fantastic modifying additions with the Collector drawing together any other multiplier figures on the screen and creating a big win. And the Dealer will multiply other multiplier values in a ‘V’ shape. Both of the above can be persistent.

Wild symbols come in three formats and these are X-Blaster Wilds, Exploding Wilds and regular Wilds. Regular Wild symbols need no introduction but the X-Blaster Wild and Exploding Wild are a little different. X-Blasters will replace a selection of random symbols in an ‘X’ shape and the Exploding Wild will blow up all payout symbols within an ‘X’ shape area above and below itself.

Players in the UK will be able to experience the regular Bonus game with 10 free spins available and multipliers now sticking around throughout the spins. It's also possible to see persistent multiplier modifiers but they aren't guaranteed. For this privilege, you will have to be in an area that allows you to pay a hefty 500x your stake and in this instance, still only 10 plays are available but one of the multiplier modifiers will be guaranteed. This is quite a big gamble to take. 

The other buy in option is to pay 100x for the regular Bonus game. This is all part of the X-iter feature which also gives players the chance to pay 25x for a persistent multiplier and 2x to see a multiplier strike where a random number of multipliers are added to the reel. Finally, there’s triple the chance to trigger the Bonus game with the Bonus Hunt option which will cost 3x.

Oxygen - Oxygen Bubbles

Oxygen Bubbles

When winning symbols are removed, they start an oxygen reaction that leaves a multiplier behind. Another win occurring in the same place doubles the multiplier. Collectors can gather up these values and Dealers can multiply any multiplier values within a ‘V’ shape.

Oxygen - Multiplier Strike

Multiplier Strike

Without having to wait for a winning combo to introduce multipliers, the Multiplier Strike feature will add some randomly instead!

Oxygen - Special Wilds

Special Wilds

Regular, X-Blaster and Exploding Wilds will all add to the experience. Regular ones simply substitute for other regular payers while X-Blaster Wilds replace all symbols in an ‘X’ shape. Exploding Wilds remove all regular symbols in an ‘X’ shape above and below.

Oxygen - Bonus Game & Super Bonus Game

Bonus Game & Super Bonus Game

Three Bonus symbols start the Bonus feature and now the multipliers stay in place throughout your 10 free games. During the Super Bonus feature, you’re guaranteed to see a persistent Dealer or Collector.

Oxygen Review

We've seen ELK Studios produce many of these features and modifiers in previous slots but I can't remember a time when they all came together so seamlessly. It's everything I hoped for and more, and I'm pretty sure you're going to agree.

Design

There's an animated format over at ELK Studios that seems to work perfectly throughout their complete range of slots lately. The graphics are crisp and fun, the soundtrack is apt and the sound effects do a perfect job. Naturally, you'll see a few oxygen bubbles making their way up to the surface and the Wild symbols can completely destroy the reels at times.

Gameplay

I'm not a fan of disjointed Base Games and Bonus features—who is?—and ELK Studios always does me proud in this respect. The list of modifying opportunities and little multiplier features stay with you at all times and they just get more potent as the Bonus feature arrives. It's a flawless slot journey.

Win Potential

Sometimes I look at a max payout figure and think this is going to be an impossible task to achieve. Not so in Oxygen and I fully expect the 25,000x max win to be smashed fairly quickly. The RTP is the regular 94% and the volatility isn't as high as you would imagine.

My Verdict

I think I've banged on about Oxygen enough for you to get the message that I simply love this game! It pulls everything together seamlessly and keeps you engaged from the very first time you hit that spin button. I probably wouldn't take the Bonus Buy option if I had the choice because I think it's just too much of a gamble to take and this bodes well for other UK-based players. I think you'll get just as much enjoyment out of the Base game and the potential of triggering the Bonus game naturally as anyone else would from buying straight in.

Paul spent plenty of time in arcades up and down the UK discovering all of the best fruit machines and watching them grow into the incredible online slots we see today. He still loves the basic format but also has a soft spot for games with big bonus rounds that progress as you play. Immortal Romance is one of his favourite slots of all time.
