Oxygen 2 Slot Overview
Oxygen 2 is a casino slot from ELK Studios, submersing players for the second time in the breathtaking (quite literally, if you run out of O) aquatic settings where bubbles are worth more than gold. The original Oxygen slot launched at the end of 2023, making some pretty solid waves with its multiplier-based gameplay "borrowed" from hits like Sugar Rush by Pragmatic Play. As we grew to expect from the Swedish creative minds, the game competently expanded the base features with additional symbols capable of enhancing the values beyond forming standard clusters. In this sequel, the underwater adventure continues, inviting even more unique functions to elevate the excitement of every spin further. Marine creatures like jellyfish and octopuses will swoop in to boost the multipliers, while the explosive naval mines will provide various transformations on the grid. Remember to bring a solid supply of oxygen, as we'll need to go deep in order to find the top prize of 25,000x the bet.

Oxygen 2 is a video slot from ELK Studios with 6 reels, 7 rows, and a cluster-pays winning format, requiring 5 or more symbols to align vertically and/or horizontally. Players can choose their stake from a range of options, starting from a Min.bet of 0.20 up to a Max.bet of 100. The game offers a relatively temperate default RTP of 94.00% connected with a high volatility rating. The top prize is capped at 25,000x the bet.
Like its predecessor, the game offers a vast arrangement of valuable features that will help players land big wins. The features of Oxygen 2 are Avalanche, Big Symbols, Oxygen Bubbles, Multiplier Strike, Octopus, Jellyfish, Blaster Wild, Exploding Wild, Bonus Game, Super Bonus Game, and Feature Buy.
Oxygen 2 Slot Information
After diving under the surface and reaching the ocean bed, we find ourselves inside a strange installation of steel and pipes overgrown with vibrant corals. Whether these are remains of some unlucky submersible or a scientific station that got blown to bits, it's hard to tell. Either is possible, given the bundle of naval mines floating threateningly in the background. The situation looks much more cheerful in the middle of the view, where colorful symbols fill the unframed playing area to an upbeat dance tune. Whenever at least 5 identical icons connect vertically and/or horizontally, a payout will be awarded. The immersive aquatic world is accessible from any modern device, be it a desktop, a smartphone, or a tablet.
Among the low-value symbols, we recognize three buoys in different colors, green, orange, and pink, awarding between 10x and 20x the bet for sets of 16 or more. The high-value ones are depicted by a green snail, an orange crab, a pink fish, and a red octopus. Prizes for matching 16+ identical premium symbols in a cluster range from 25x to 100x the bet. Various special icons can also find their way into the grid, including Octopus, Jellyfish, Wilds, Blaster Wilds, Exploding Wilds, and Bonus Symbols.
Oxygen 2 Slot Features
What is the max win in the slot Oxygen 2?
You can win up to 25,000x the bet.
What features are available in the slot Oxygen 2?
The features are Avalanche, Big Symbols, Oxygen Bubbles, Multiplier Strike, Octopus, Jellyfish, Blaster Wild, Exploding Wild, Bonus Game, Super Bonus Game, and Feature Buy.

Avalanche
Each winning combination will burst and disappear from the grid, making room for the remaining symbols to drop down. The view will then be completed by new symbols coming in from above.
Big Symbols
Any paying symbol can appear in its larger variant of 2x2, 3x3, or 4x4 in size. Big Symbols can also carry multipliers.
Oxygen Bubbles
Every winning symbol activates its position. Any consecutive wins happening in the same spot during the same round will double its multiplier up to a maximum of 2,048x. Any wins happening on activated positions will benefit from a total value of underlying multipliers.
Multiplier Strike
The feature can activate on any regular drop or free drop and place a random amount of multipliers on the grid.
Octopus
Randomly, on any spin, an octopus can be added to the grid. If a winning cluster occurs in its position, the Octopus will activate and add additional multipliers to the current win multiplier.
Jellyfish
Jellyfish can randomly appear and swim across the playing area. They will stop in various positions, increasing their multipliers.

Blaster Wild
Blaster Wilds can explode in an X-shape or Plus-shape from their center. When they do, a random paying symbol or Wild is chosen and replaces the symbols in all affected positions.
Exploding Wild
There are two versions of the Exploding Wild that will affect positions in cone-shaped areas either above and below or to the left and right of it. Symbols in those positions will be removed, thus causing an avalanche.
If a Super Exploding Wild lands, it will also activate any inactive Oxygen Bubbles.
Bonus Game
Achieving 3 Bonus symbols throughout the same round activates the Bonus Game. 10 free drops are awarded, during which all Oxygen Bubble multipliers are persistent and don't reset between spins. Additionally, the Octopus is also present at all times, moving to a random position on every spin.
Super Bonus Game
Achieving 4 Bonus symbols throughout the same round activates the Super Bonus Game. This variant plays identically to the regular one but with the Jellyfish feature triggered on every spin.
Landing 2, 3, or 4 Bonus symbols during either round awards +3, +4, or +7 free drops (the last option also triggers the Super Bonus Game if achieved in the regular Bonus Game)

Feature Buy
Customary to releases by ELK Studio, the game offers a range of options to trigger features instantly from the X-iter menu.
3x = Bonus Hunt, tripling the chance to trigger the Bonus Game.
10x = a spin with at least 3 special Wilds guaranteed.
25x = a spin with a guaranteed Octopus and Multiplier Strike.
100x = standard Bonus Game.
500x = Super Bonus Game.
Oxygen 2 Slot Conclusion
As far as sequels go, we always repeat that it's crucial to hold a careful balance when producing one. After all, it's all about surpassing the success of the predecessor by making existing players stay on and attracting some new ones in the process. Hence, the mechanics shouldn't stray too far from the original while introducing new features that will enhance the familiar feeling. Oxygen 2 does an excellent job in that area, executing precisely what we described. Before we jump into the nitty-gritty of the mechanics, let's stop for a moment and absorb the design. The scene, while majorly similar to the first installment, comes with some dramatic details added and a transformed set of symbols. As usual, the top quality can be seen all around, shining with plenty of unique elements that follow the overall theme. Supplementing the artwork are spectacular animations tied to wins and feature triggers.
Doubling multipliers in winning positions is an extremely potent feature, even on its own, as the release of the aforementioned Sugar Rush has proven. The first Oxygen slot cleverly weaved in additional Collector and Dealer symbols to further boost their attractiveness with more ways of increasing the values. In the sequel, producers decided to drop them on account of the more theme-fitting Octopus and Jellyfish that certainly bring more of an aquatic vibe. Their functions are slightly different, but their goal has remained unchanged - it's all about elevating the multipliers to the highest possible value. Perhaps some players may have expected more significant changes than just reshuffling the method of boosting those values, but regardless, the game offers a solid dose of excitement and a respectable win potential of 25000x the bet.
Oxygen 2 is a careful leap forward from the original, offering similarly engaging gameplay in a vibrant aquatic environment.
