end up further away from the final square after their move, than before it. In the book Winning Ways, the authors propose a variant which they call Adders-and-Ladders which, unlike the original game, involves skill. Instead of tokens for each player, there is a store of indistinguishable tokens shared by all players. The illustration has five tokens (and a five by five board). There is no die to roll; instead, the player chooses any token and moves it one to four spaces. Whoever moves the last token to the Home space (i.e. the last number) wins. Specific editions The most widely known edition of snakes and ladders in the United States is Chutes and Ladders, released by Milton Bradley in 1943. The playground setting replaced the snakes, which were disliked by children at the time. It is played on a 10x10 board, and players advance their pieces according to a spinner rather than a die. The theme of the board design is playground equipment, showing children climbing ladders and descending chutes. The artwork on the board teaches morality lessons: squares on the bottom of the ladders show a child doing a good or sensible deed, at the top of the ladder there is an image of the child enjoying the reward; squares at the top of the chutes show children engaging in mischievous or foolish behavior, on the bottom of the chute the image shows the children suffering the consequences. Black children were depicted in the Milton Bradley game for the first time in 1974. There have been many pop culture versions of the game, with graphics featuring such children's television characters as Dora the Explorer and Sesame Street. It has been marketed as "The Classic Up and Down Game for Preschoolers". In 1999, Hasbro released Chutes and Ladders for PCs. In Canada the game has been traditionally sold as "Snakes and Ladders" and produced by the Canada Games Company. Several Canada-specific versions have been produced over the years, including a version with toboggan runs instead of snakes. An early British version of the game depicts the path of a young boy and girl making their way through a cartoon railroad and train system. During the early 1990s in South Africa, Chutes and Ladders games made from cardboard were distributed on the back of egg boxes as part of a promotion.
