Boxed In: Dots and Boxes

The classic pen-and-paper game, now on your phone. Connect dots, close boxes, and capture more squares than your rival.

HOW TO PLAY • On your turn, tap a side between two dots to mark it with your colour. • Complete a square and it is yours — and you play again! • When the board is full, whoever holds the most squares wins. • A tie is settled by sudden death: first box wins.

THREE WAYS TO PLAY • Against the computer, at three difficulty levels. • With a friend on the same phone, taking turns. • Online, against another person in real time.

FEATURES • Boards from 5×5 up to 9×9. • Choose your colour and who goes first. • The computer and same-phone modes work offline: play anywhere. • Sound effects and music, each with its own switch. • A paper or blackboard background, and a colour-blind friendly palette. • Available in ten languages. • No accounts, no sign-ups. You never need to give an email or a name.

PURCHASES Free, with ads between games. "Remove ads" gets rid of them for good. The "Aliens vs Astronauts" pack swaps the pieces and the board if you fancy a different face.

Easy to learn, hard to master. Do you accept the duel?
