About Dots and Boxes

A browser version of the pencil-and-paper classic Dots and Boxes. Take turns claiming a line between two dots; completing the fourth side of a box scores it for you and gives you another turn.

Play a friend on the same device, or against a simple computer opponent that avoids handing you free boxes when it can.

How to play

  1. Click or tap a line between two dots to claim it.
  2. Completing the fourth side of a box scores that box for you and lets you move again.
  3. Watch out: claiming the third side of a box usually hands your opponent a free box next turn.
  4. When every box is claimed, whoever has more boxes wins; equal scores are a draw.

Controls

  • Click or tap a line between two dots — claim it
  • Tab and Enter — keyboard play
  • Restart — start a fresh board

Frequently asked questions

Why did the computer let me complete a box?

When every remaining line would hand away a box, the computer picks one anyway — at that point every move is equally risky, so it just claims a line.

Can two people play on one device?

Yes — choose Two players and take turns tapping lines on the same board.
