BIG FISH! on a phone: a pink betta fish, its mass, and the growth it gains from each tap.

How it works

Every tap makes it heavier

1

Tap anywhere

Each tap adds mass to your fish. Land a critical tap and it counts three times.

2

Watch it grow

Grams turn into kilograms, kilograms into tonnes. Coins you earn buy five upgrades that speed it all up.

3

Become something else

Reach the right mass and your fish evolves on its own. There are 30 species, each bigger than the last.

The way down

30 species. We'll show you five.

The rest you meet by growing into them. Keep scrolling: the water gets darker and the fish get bigger.
