Dots & Boxes

How to play

The classic pencil-and-paper line game, played against an AI. Draw one edge per turn on a grid of dots — completing the fourth side of a box claims it and earns you another turn.

Rules

  • Click any open edge between two dots to draw it.
  • Completing the fourth side of a box claims that box and gives you an extra turn.
  • If your line doesn't complete a box, play passes to the AI.
  • Whoever claims the most of the 16 boxes when the grid is full wins.

Tips

Never draw the third side of a box unless you have to — that hands the AI a free point next turn. When you're forced to give one away, give away the smallest chain you can.
