Winnings are presented in the player's currency.

The game is played in two modes; normal mode and bonus mode with free drops.

The Wild symbols substitute for any payout symbol. A winning combination of only Wild symbols pays as the highest payout symbol.

Oxygen 2 uses the Avalanche mechanic: The game starts with a symbol drop. All winning symbols are collected and are either exploded or, if the symbol is a special wild, activated to be exploded later. Remaining symbols are affected by gravity, meaning they will fall vertically until they reach a resting position. New symbols drop in to fill the empty spaces.

The avalanche continues as long as new winning combinations appear.

The first time a symbol explodes, an oxygen bubble is activated. Every time a symbol explodes on the bubble position the multiplier value is doubled (the activated oxygen bubble counts as x1). Oxygen bubbles are not affected by gravity. All oxygen bubbles and their multiplier values are persistent between free drops in bonus mode.

The Multiplier Strike feature places a random amount multipliers on the symbol grid. The multiplier strike feature can trigger in any symbol drop or free drop.

The Jellyfish feature is a random feature. One or more Jellyfish arrive carrying multipliers. Each Jellyfish will stop at a random number of symbol positions. On each symbol position where a Jellyfish stops, the Jellyfish will add the carried multiplier. If there already is a multiplier where a Jellyfish stops, the existing multiplier will be added to the Jellyfish multiplier and the Jellyfish multiplier will be added to the existing multiplier.

An Octopus can randomly appear on the game grid and place itself behind one symbol position. The Octopus feature is triggered if you win on the symbol position with the Octopus. The Octopus feature will then add a random selection of the available multipliers outside of the winning cluster to the win, increasing the win multiplier.

The Exploding Wild activates an explode feature when it is part of a winning cluster. The explode feature removes all payout symbols within two cone shaped areas facing up and down from itself or to the left and the right from itself. The feature triggers when no more winning combinations appear. Exploding Wilds and

Blaster Wilds within the cone shaped areas will be activated.

The Super Exploding Wild activates all unactivated oxygen bubbles behind the exploded symbols.

The Blaster Wild triggers when it is part of a winning cluster. The Blaster feature selects a random payout symbol or Wild symbol. The Blaster Wild will then explode and replace all payout symbols with the selected symbol in an X- or Plus- shaped pattern. Any Exploding Wilds or other Blaster Wilds along the pattern will be activated. Symbols affected by multiple Blaster Wild patterns will turn into Wild symbols.
Symbols of size 2x2, 3x3 and 4x4 may appear in any symbol drop. All big symbols are counted as consisting of the number of 1x1 symbol instances it covers, e.g. 2x2 is counted as 4 standard 1x1 symbols. The big symbols can also have their own multiplier.

3 bonus symbols trigger the bonus game with 10 free drops. Multipliers are persistent when entering the bonus game and between freedrops.

The Octopus is persistent in the bonus game. The Octopus moves to a random position in the beginning of each free drop.

4 bonus symbols trigger the super bonus game. During the super bonus game, the Jellyfish feature will be triggered in every free drop.

The bonus game and super bonus game can be retriggered.
