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%.

ELK's cluster reef with doubling oxygen bubbles up to x2,048 - 25,000x cap, but 94% RTP

Pros & Cons

Előnyök
  • Oxygen Bubbles doubling on repeat explosions, up to x2,048 on one position, is a genuinely strong multiplier engine
  • Bubbles, multipliers and the Octopus persist between free drops, so a bonus round compounds instead of resetting
  • 25,000x is a serious ceiling, well above most cluster games
  • The wild set is unusually varied: cone-clearing Exploding Wilds, the Super variant that lights unused bubbles, and the pattern-rewriting Blaster Wild
  • Five X-iter buys from 3x to 500x, including a 25x Octo Strike that guarantees the Octopus plus a Multiplier Strike
Hátrányok
  • 94.00% RTP is low - that is the number to weigh everything else against
  • High volatility with the real money locked behind persistent bubbles that take repeat hits to build
  • The Jellyfish animation is slow, and a run that ends without paying makes you feel every second of it

Mitől különleges ez a nyerőgép

  1. Oxygen Bubbles & Multiplier Strike

    The first symbol explosion on a position lights an oxygen bubble at x1, and every subsequent explosion on that same position doubles its value - up to x2,048 on a single spot. Multiplier Strike scatters a random number of extra multipliers across the grid, and in the bonus round the bubbles carry over from drop to drop.

  2. Wilds: Exploding, Super Exploding, Blaster

    An Exploding Wild that joins a winning cluster clears all pay symbols in two cone-shaped areas facing left/right and up/down, activating any other wilds inside them; the Super Exploding Wild also lights every unactivated oxygen bubble behind the symbols it removed; the Blaster Wild picks a random pay or wild symbol and replaces symbols in an X or plus pattern, turning them wild if hit more than once.

  3. Bonus Game, Super Bonus & X-iter

    Three bonus symbols in a round award the Bonus Game with 10 free drops; four award the Super Bonus, where the Jellyfish feature fires before every drop. Landing more bonus symbols mid-round adds extra drops, up to +7. The X-iter buys are 3x for Bonus Hunt, 10x for a spin with 3+ special wilds, 25x for the Octo Strike, 100x for the Bonus Game and 500x for the Super Bonus.

Ítélet

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.

  • What is the max win in Oxygen 2?

    25,000x the bet - one of the higher caps in ELK Studios' catalogue. It is built from oxygen bubbles doubling on repeated explosions, up to x2,048 on a single position, layered with the other multiplier features.
  • What is the RTP of Oxygen 2?

    94.00%, which is ELK's current standard and below the wider market average. Check the in-game info panel, and weigh the 25,000x cap against that number rather than looking at it in isolation.
  • How do the Oxygen Bubbles work?

    The first explosion on a grid position lights a bubble at x1. Every further explosion on that exact position doubles the bubble's value, up to x2,048. In the Bonus Game and Super Bonus the bubbles persist from drop to drop, along with the multipliers and the Octopus.
  • What is the difference between the Bonus Game and the Super Bonus?

    Three bonus symbols award the Bonus Game with 10 free drops. Four award the Super Bonus, where the Jellyfish feature triggers before every single drop. Extra bonus symbols during either round add more drops, up to +7.
  • What can you buy with X-iter in Oxygen 2?

    Five options: 3x the bet for Bonus Hunt, 10x for a spin with at least three special wilds, 25x for the Octo Strike with a guaranteed Octopus and Multiplier Strike, 100x for the Bonus Game and 500x for the Super Bonus. The full demo is playable free on this page.
