Oxygen 2
Oxygen 2 is ELK Studios going back underwater with one of the busiest grids the studio has built: 6 columns, 7 rows, cluster pays that need five or more identical symbols touching horizontally or vertically, and an Avalanche that keeps refilling until the wins stop. The engine is the Oxygen Bubbles. The first explosion on a position lights a bubble at x1, and every further explosion on that same spot doubles it - all the way to x2,048 on a single position. Everything else in the game exists to put explosions where the bubbles are: Big Symbols land 2x2, 3x3 or 4x4 and can carry multipliers, Exploding Wilds clear two cone-shaped areas and set off other wilds inside them, the Blaster Wild rewrites an X or plus pattern of symbols, Jellyfish drift in holding multipliers, and the Octopus hides behind a position waiting for a win to land on it. Three bonus symbols award 10 free drops, four open the Super Bonus, and bubbles, multipliers and the Octopus all persist between drops. Max win is 25,000x; RTP is 94.00%.

Ítéletünk: Oxygen 2
ELK builds slots the way engineers build machines: every part connects to another part, and Oxygen 2 is one of the tighter-geared examples. The oxygen bubbles are the whole design - a position that has already paid becomes worth hitting again, and again, doubling each time to a theoretical x2,048 - and every wild, Big Symbol, Jellyfish and Octopus in the game exists to steer explosions back onto the spots you have already lit. In the bonus round, where the bubbles carry between drops, that gearing becomes the thing you are actually playing for, and a good Super Bonus can spiral toward the 25,000x cap in a way the sedate first game never managed. It is a diagonal step rather than a dive forward, and that is a fair description. The number to be honest about is 94.00% RTP. That is ELK's current house standard, it is below the market, and on a high-volatility game it means the quiet stretches cost you more than they would elsewhere. Worth playing for the mechanics, worth demoing before you commit, and worth checking your casino's info panel to see exactly which configuration you are being served.
