Feed, puff, merge into a whale
Only for iPhone
Free · In‑App Purchases
iPhone
Tap a fish to feed it and it puffs up, pushing its neighbors. When a puffed fish touches the same kind, they merge into a bigger one. Ten species from puffer to whale.
Feed the fish, watch them puff, merge them into bigger fish. The goal: a whale.
◆ Tap = feed
Tap a fish in the tank and it eats, then puffs up once, pushing everything around it.
Choosing which fish to feed is your one move.
◆ Same kind touching = merge
When a puffed fish touches another of the same kind, they merge into the next fish up.
Puffer → Porcupine → Bream → Octopus → Turtle → Sunfish → Dolphin → Orca → Whale Shark → Whale. Ten species.
A merge that triggers another merge is a chain, and chains multiply your score.
◆ Whale fusion, then a whale feast
When two whale sharks merge, a whale is born. How many whales you can make in one game is the real measure of skill.
Merge two whales and a giant whale appears, gulps every puffer, porcupine and bream in the tank, and swims back to the sea.
◆ Watch out for urchins
Every 12 taps an urchin comes down the pipe instead of a fish. It just sits there taking up space, but tap it and it bursts, blasting the fish around it.
Two urchins touching set off a double blast. Danger or opportunity, depending on where they land.
◆ Game over when the tank is full
Every tap sends a new fish down one of the pipes. When a fish settles above the water line, the game is over.
Keep merging to make room, and aim for the big ones.
◆ Look back and share
When a game ends, "See the tank" lets you look over your final tank, and "Share" posts your score with a picture of the tank to X, LINE or anywhere else.
◆ Records and rankings
Your top 10 scores are kept on the device. Pick a name to join the online ranking and your best score appears on the Today, This week and All time boards (Today resets at midnight JST, This week on Monday at midnight JST).
No account is needed. Joining is optional and the game is the same either way.
◆ Pick up where you left off
A game in progress is saved automatically. Next time you open the app, choose Continue to go back to your tank.
◆ Quiet by default
Sound effects and music respect the silent switch, and they never interrupt music or podcasts playing from another app.
◆ Everything is free from the start
The whole game, the rankings, the records. There is one in-app purchase, a one-time "Remove ads". It changes nothing about the game; it only removes the ads.
For you if:
・you like merge puzzles
・you'd rather choose where to push than where to drop
・you want to see a puffer fish puff
