Use your math skills to eat your way up the ocean food chain. Become the biggest fish in the sea by answering questions correctly, and unlock new playable characters as you progress.

Start the game by hitting play, then select the grade of math skill you want to practice. Afterwards read the question and then tap on any fish that is swimming with the correct answer.

If you answer correctly, your fish will grow in size. Be careful though! Incorrect answers will cause you to burp up the fish you've eaten, and if you get too small you'll be eaten up yourself!

Good skills but gets stuck on same skill

Fun math app but gets stuck on one skill. Even when passed all levels of a skill doesn’t move on to next unless you customize each time. With a fix would be great!

Under the sea... of math

You use math to solve the equations and satisfy your hungry fish. The cartoon graphics and animations look good/ smooth. I like the mix of math and underwater theme; fun way to learn.
