Oxygen

G’day! Keen for a bit of a splash? Oxygen takes you deep into a vibrant blue world that’s all about the simple joy of play. We’re big fans of those little moments of unexpected fun, and this slot is sweet as for anyone who enjoys a bit of a laugh under the sea. It uses a massive 7x7 grid with a cluster pays mechanic, so you can forget about tracking lines. Just get five or more matching symbols touching each other and you’re sorted. When a win lands, the symbols disappear and new ones drop down thanks to the cascading reels, keeping the action flowing at a steady pace.

Bubbles with a Boost

The real highlight has to be the multiplier bubbles. These aren't just for show; they pop up after a winning cluster is cleared. If a new symbol lands on a bubble and forms part of another win, it’s a bit of a result as a multiplier is added to the payout. These bubbles can even double up to reach 2048x, which adds a cheeky bit of variety to your session. It’s that little spark of joy we call UMO. Sometimes the Multiplier Strike will trigger randomly, launching a bunch of bubbles onto the reels to keep things interesting. It’s all about those small, playful surprises.

All Set for the Deep

If you track down three or more bonus symbols, you’ll jump into the extra spins feature. During this round, the multiplier bubbles stay sticky on the grid, meaning they don’t reset between drops, which is a nice touch. The underwater theme is bright and energetic, with golden divers and scuba gear acting as the main symbols. It’s easy to get the hang of and looks great on your phone.
