Fans of the Oxygen slot series by ELK Studios can finally breathe a sigh of relief now that the third game is out in all popular online casinos.
Sure, it’s an obvious opening to use such a pun, but you’ll thank me later as I, along with the eminent David Slottenborough, present a soon-to-be-awarded, award-winning slot review for Oxygen 3 that promises to be breathtaking. Stick around for an air-raising review of features, mechanics, bonuses, and payouts.

In the enigmatic style of a Jules Verne novel, witness David Slottenborough venture into the depths of a wet liquid substance as he bravely plays this slot machine for real money.
Join me, David Slottenborough, as I travel 100 meters into the warm waters of a place marked by the likes of fish waste and shark excrement, to bring you accounts of my first-hand meeting with Oxygen 3.
Slots from ELK Studios have a common mechanism running through them, which can make winning more challenging. The Oxygen 3 slot has an RTP of 96% and features a high volatility setting. Keep this in mind when choosing to play this game. Budgets can deplete quickly, and while payouts can be substantial, they are less frequent.
The game is played on a grid layout of six reels and seven rows and formulates wins through a Cluster Pays mechanism. Match five or more symbols in a cluster to receive a payout; the bigger the cluster, the larger the win. The highest single win is 25,000 times your bet. Bets can range between $0.20 and $100. If betting at the higher end, the biggest jackpot reaches $2,500,000!
While the gaming itself can be trickier than lower volatility slots, it can’t be argued that ELK Studios skims on the features of a game, which provides plenty of opportunities for players to win. Oxygen 3 comes with multipliers, special features like Exploding Wilds, large symbols, a Bonus, and a Super Bonus round, plus the X-iter feature.
The game is a little upgraded from the two that came before it. It’s by no means a million miles better, and the game itself isn’t exactly a jaw-dropping experience. However, given the high quality that you get from ELK Studios, it’s good enough to at least give its demo mode some attention compared to what has been released this month so far. Essentially, you won’t have your breath taken away.

100 meters beneath sea level, sunlight becomes diminished, and the temperature drops to a chill that makes your unmentionables disappear up inside you. I observe the new surroundings of this game. Gone are the shipwreck and pipelines of the first two games, to be replaced by an underwater monorail and control room.
I begin recording my findings as I play the slot with $2 spins. The first spin activates a win, which, in turn, produces an Avalanche feature that produces two more wins. In total, only $1.60 is paid out. The second spin repeats these actions, resulting in a minor $0.40 win. The fourth spin lands the Squid symbol, which randomly positions Wild symbols over the grid. This action leads to a $3 win. So far, the hit rate of this game has been good, with wins landing every three spins or less, and this happens again on spin seven, with a win of $1.20.
Now, so far, the values being won are underwhelming, but this is a trait of a slot built with a low RTP and a high volatility setting. Spins eight, nine, and ten all land a win, but none of them is more than $1. To examine the behavior of this game, I increased the wager to $4 per spin.
The first spin forms a win, which is less than the value of my bet. The same can be said for the third spin. It would appear that a somewhat ‘payoff’ has formed, with the fourth spin producing more than six consecutive wins to yield a payout total of $7.20. While this is an improvement, it’s hardly positive that a run of wins can result in such a meager return.
For the seventh spin, the Multiplier Strike feature activates, although it results in no win. Spin eight produces $1.20 from three consecutive wins. With all ten spins played at $4, I decide I’ve seen enough to know that this game is reluctant to reward the efforts of the player and to enhance the value of a single bet when a win lands.
