How to play Dots and Boxes

Connect only neighbouring dots horizontally or vertically. A fourth side claims the box and gives the same player another turn.

Rules and strategy methods

On a 3×3-box board, h:0:0 is the top edge of the first box. The board has 4×4 dots because sizes count boxes, not dots.

The game ends only when all 24 edges are filled; the two scores then total 9.
