Oxygen 2 Features & Bonus Games

Don’t miss these exciting special features waiting to be triggered! Keep your eyes peeled for the mega symbols that can all automatically have multipliers attached.

Oxygen Bubbles & Multiplier Strike

When a symbol explodes for the first time, an oxygen bubble springs to life at that position. Every time a symbol explodes on an oxygen bubble, the multiplier value doubles, starting from an initial value of x1.

Oxygen bubble multipliers stay in place during a symbol drop, with the maximum single value reaching an impressive 2,048x. During any spin, the Multiplier Strike feature can randomly place a number of multipliers on the grid, adding even more excitement!

Octopus & Jellyfish Features

Every now and then, one or more Jellyfish might surprise you by appearing with some big multipliers! Each Jellyfish multiplier will pause at a few random spots on the grid, generously adding their carried multiplier to your score.

If a Jellyfish lands on a spot that already has a random multiplier, the new Jellyfish multiplier and the existing one will combine to boost your totals even more.

Keep an eye out for the Octopus settling behind a symbol. If there's a win on that specific symbol position, the Octopus feature activates, bringing in a mix of available extra multipliers from outside the winning cluster to enhance your win even further!

Exploding Wild & The Blaster Wild

The Exploding Wild comes to life with an exciting feature whenever it's part of a winning cluster. This feature eliminates all random payout symbols in two cone-shaped areas that fan out to the left and right, as well as up and down. It activates when there are no more wins to chase.

You'll also see special wild symbols, such as Exploding Wilds and Blaster Wilds, spring to action within those cone areas. The Super Exploding Wild game mode activates all the unactivated oxygen bubbles hiding behind those exploded symbols!

The Blaster Wild comes into play when it’s part of a winning cluster. When the Blaster feature is triggered, it selects a random pay symbol or wild symbol and sets off an explosion, transforming all the pay symbols in either an 'X' or a plus-shaped pattern into identical symbols. If any special symbols are part of multiple Blaster Wild patterns, they will turn into wilds, providing even more chances for big wins.

Free Spins Feature & Special Symbols

Land 3 or more scatter symbols, and you’ll be rewarded with 10 free spins. During these free spins, all oxygen bubbles and their multipliers hang around to help you out. Plus, the friendly Octopus joins in the fun during the bonus game, moving to a new random position at the start of each free spin.

If you manage to hit 4 scatter symbols in the base game, you'll unlock the super bonus game! In this feature, the Jellyfish multiplier feature pops up before each free spin to give you extra chances.

Bonus Hunt - Costs 3.00x per spin

Bet Sizes, Max Win & Return to Player (RTP)

To dive into the fun of Oxygen 2, simply set your betting range anywhere between 0.20 and 100.00 for each round. Once the spins start, rest assured that the trusty random number generator (RNG) is ready to keep things fair for every outcome, even during those special features!

This is a highly volatile slot with a return to player percentage (RTP) of 94.00%, so it’s a good idea to keep an eye on your budget as you play. While the house edge sits at 6.00%, remember that the odds are on your side as you try for that thrilling 25,000x max win!
