Snakes an ladders, or Chutes and ladders, is a classic children's board game. It is played between 2 or more players on a playing board with numbered grid squares. On certain squares on the grid are drawn a number of "ladders" connecting two squares together, and a number of "snakes" or "chutes" also connecting squares together. The size of the grid (most commonly 8×8, 10×10 or 12×12) varies from board to board, as does the exact arrangement of the chutes and the ladders: both of these may affect the duration of game play. As a result, the game can be represented as a state absorbing Markov chain.
