Number & Letter ChallengeParent sign in

Sums that roll. Words that click.

Two games that make arithmetic and spelling feel like play, for children aged about 5 to 13. Grown-ups set things up; children just pick their avatar and go.

Accounts are for adults. Children play on profiles you create — no email needed.

Against the clock

Timed rounds with ten levels that grow with your child.

Fair competitions
