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!
