Start as a tiny tadpole. End as the biggest creature in the ocean. BIG FISH! is a relaxing tap-and-grow game. Every tap adds mass to your fish. Grow enough and it evolves into a new species: 30 in total, from a 2-gram tadpole to a 150-tonne blue whale. TAP TO GROW • Tap anywhere on the screen. Every tap makes your fish heavier. • Land critical taps for triple growth. • Watch your fish swim and turn in a living, animated ocean. EVOLVE 30 SPECIES • Guppy, goldfish, lionfish, shark, orca, blue whale and many more. • Every species is bigger than the last. • Evolution is automatic: reach the mass, become the fish. UPGRADE YOUR GROWTH • Earn coins as you play and spend them on five upgrades. • Grow faster per tap, per second and while you are away. KEEPS GROWING WHILE YOU'RE AWAY • Your fish keeps growing for up to 12 hours while the game is closed. • Come back, collect your reward and carry on. OUTGROW THE OCEAN • An ocean of 600 rivals ranked by mass: real players, plus ocean fish while players are few. • Swim past them one by one on your way to #1. FAIR AND SIMPLE • No ads. • No account and no sign-up. • Works offline. • Optional in-app purchases of gems speed up growth. Every species can be reached just by playing. How big can you get?
