Crazy10s

Make every line add up to 10.

Crazy10s is a two-player tile game with numbers. You and your opponent build on one shared board, and every line your move touches, across or down, has to add up to exactly 10. Quick to learn, hard to put down.

HOW IT WORKS • You hold seven tiles, 0 to 9. Drag them onto the board and tap Play. • Every row and column your tiles touch must add up to exactly 10. • Build off any tile on the board, yours or your opponent's. One move can finish several lines at once, and that's where the big points are. • Wild tiles become any number you need. • The 13×13 board has bonus squares that double or triple your score, and each corner is worth an extra 50.

WAYS TO PLAY • Invite a Friend: send a link by text or email. They tap it, pick a name and they're in. • Random Match: get paired with another player in one tap. • vs Computer: Easy, Medium or Hard. Hard plays the best move it can find. • Practice: play both sides yourself and learn the board at your own pace.
