How to play

A minute to learn. The whole game is one small decision, over and over.

Draw a line

On your turn, connect two neighbouring dots with one line.

Claim the box

Close a square’s fourth side and it’s yours, stamped with your mark.

Claim, then go again

Every box you close earns another turn, so a whole chain can fall at once.

Mind the third side

Draw a box’s third side and you hand your rival the fourth. Stay patient.
