2. Checkers
Checkers, (or Draughts as it’s known in the UK) is a game for two players, based on a black and white tiled board. One players has the light discs, the other the dark ones. Players take turns to move diagonally to an empty square, ‘capturing’ their opponent’s discs by jumping over them. Enthusiasts would argue the game’s popularity is due to the number of possibilities on the board: over 50 billion, billion!
