Dots and Boxes
Dots and Boxes is a pencil-and-paper game for two players. It was first published in the 19th century by the French mathematician Édouard Lucas. The game is played on a grid of dots, and the players take turns drawing lines between the dots. The goal is to complete a box by drawing the fourth side. When a player completes a box, they get a point and take another turn. The game ends when all the boxes are completed, and the player with the most points wins.
