Oxygen 2 Slot Overview
Oxygen 2 is one of the slots created by Elk Studios. Deep under the ocean, a submarine has sunk and has been colonised by strange-looking marine life. The base game is presented on six reels with seven rows, with wins created by symbols appearing in clusters.
Once a winning symbol explodes, an oxygen bubble activates with a win multiplier. Every time a winning symbol explodes, the multiplier is doubled up to the biggest single multiplier of 2,048x.

Graphics and Theme
The game opens with us peering out of a broken submarine at marine life that seems to have been mutated and combined with rubbish. Is this a comment on nuclear fuel or littering of the ocean?
The main symbols are scary creatures, such as a crab with a spanner for a claw, a sea snail with a can instead of a shell, and a fish with a steering wheel on its back. There are also exploding mines and colourful buoys.
Soundtrack
A funky tune plays in the background but is drowned out by the electronics as the reels spin.

Volatility
The game displays high volatility.

How to Win at Oxygen 2
The game has a cluster win mechanism that triggers when at least five matching symbols connect vertically and/or horizontally.
Winning Symbols
There are seven winning symbols to be found in the Oxygen 2 slot. The wild is the top-value symbol, paying a win multiplier of 100x the stake when 16 or more combine.
Free Spins
Three bonus symbols trigger the free drops game with ten free spins. Here, all multipliers are persistent throughout the phase and the octopus appears in a random position. Four bonus symbols trigger the super bonus game in which the jellyfish feature triggers on each free drop.
Both free drops and super free drops can re-trigger as follows:
- Four bonus symbols upgrade to the super bonus drop with seven free games.
- Three bonus symbols add five free drops.
- Two bonus symbols add three free drops.
