• General Program Information

  • Checkers is a very old puzzle game. The game is played on an 8x8 checkered board. It is based on the game Draughts from England. I do not think the American rules differ from the English rules, but it is not the same as Italian Draughts. Basically, there are two sides, a "red" side and a "black" side. (The colors vary, but these are the most common, yet not the official colors). In this version, the "red" side is white, and the "black" side is black. Each side has 12 checkers, which are round discs used for pieces. The object of the game is to remove all the opponents checkers by jumping them with your own. More complete rules are available in the instructions.
