Dots and Boxes (also known as Boxes, Squares or Dots) is a pencil and paper game for two players (or sometimes, more than two). In Mexico dots and boxes is called
Timbiriche.
Starting with an empty grid of dots, players takes turns adding a single horizontal or vertical line between two unjoined adjacent dots. A player who completes the fourth side of a box writes their initial in the box just completed and takes another turn. The game ends when no more lines can be placed. The winner of the game is the player with the most boxes.
I just set up a web version on my new games site (
