How to play

Take turns drawing a single horizontal or vertical line between two adjacent dots.

If your line completes the fourth side of a box, you claim it and go again.
The game ends when every line has been drawn. Most boxes wins.
Hover near a gap to see where the line will land; click to commit.
Vs. computer, the Hard level will try the classic double-cross — leaving you the last two boxes of a chain to force you back on offer.
