Kidi Monster Math for Kids

A calm, ad-free math game for kids! Master addition, subtraction, multiplication, and division with friendly paper monsters.

Answer the sum before the meteor hits the earth! Four paper monster friends hold up the answers. Tap the right one to push the meteor back. A calm maths game for addition, subtraction, times tables and division, with no ads.

Every monster, planet and button is cut from paper, each monster has its own voice, and a wrong answer is never a dead end: the right answer glows, its monster cheers, and the next sum comes.

SAFE FOR CHILDREN
The parents' corner sits behind a 4-digit PIN, and prices, buying and restoring appear only there. A child who taps something locked hears "ask a parent", never a price.

The game is in English. It suits children from about 5 to 10.

Plusk, Mynus, Divy and Mully are ready. Can your child keep the earth safe?
