Tap a fish. Collect three of a kind in the tanks above.
Your ocean is saved automatically.
1,600 source levels
Levels 1-20 start unlocked, not completed. Complete level 20 to unlock 21, then complete each level to unlock the next. Completed unlocked levels can be replayed. Source inventories are intact; target order and bubble positions are reconstructed.
Tap a fish to send it to a matching target tank. Three identical fish complete a tank. Fish that do not match a target go to the holding area, then move automatically when a matching tank appears. If all five holding slots fill up, you lose.
Drag the water, scroll, or use Above / Below to explore the bubble reservoir. The Hint button finds a fish for an active tank. Ice bubbles thaw after three matching-target selections in neighboring bubbles. Empty a key bubble to open a chain.
Original backgrounds, bubble and aquarium art, fish Spine animations, English fonts, sounds, victory effects, and the complete base configuration of 1,600 levels. Fish species, counts, and bubble membership are retained.
The Web engine, gravity-inspired packing, four-tank scheduler, motion and interface are rebuilt. Android adaptive difficulty and ad-weighted target selection are not reproduced. Unknown fish reveal behavior is inferred.
Advanced rules are adapted: empty obstacles are display-only packing circles; extra-layer fish are all shown at once, without generating new fish; bound fish move together; fish ice and secondary locks count completed groups; masks open when their species is collected. Timed-target events use the overall level timer only. Use the clearly labeled free assists if a reconstructed rule blocks progress. These levels are not claimed to be runtime-identical.
No ads, purchases, tracking, or online events. Local saves only. Original assets and the Spine Runtime have separate licensing requirements; extraction does not grant redistribution rights.
