Fox games are a category of board games for two players, where one player is the fox and tries to eat the geese/sheep, and the opposing player directs the geese/sheep and attempts to trap the fox, or reach a destination on the board. In another variant, Fox and Hounds, the fox merely tries to evade the hounds. There are several versions known: in Britain (Fox and geese), France (Renard et les poules), Italy (Lupo e pecore), Germany (Fuchs und Gänse), Netherlands (Schaap en wolf), Sweden (Rävspel), Iceland (Refskak), Slovakia (Vlci a ovce), Russia (Volk i ovtsy/Wolf and sheep) and Nepal (Bagh-Chal).
The game Halatafl is known from at least as early as the 14th century, and it is mentioned in Grettis saga. It probably originated in Scandinavia, as a variant of Tafl. In fact, Halatafl is still played in Scandinavia with rules similar to Tafl; see below. Edward IV of England is known to have purchased two foxes and 26 hounds to form two sets of Marelles, believed to be Fox and Hounds. As Fox and Geese, the game was a favorite pastime of Queen Victoria.
Halatafl means "tail board", in Old Norse, and "tail" presumably refers to a fox's tail. As in Grettis saga, rävspelet (modern Swedish for "the Fox game") is still played with holes and pegs.
There are two fox pegs (the red pegs on the picture) and 20 sheep pegs (the yellow pegs). Like the original game, tafl, the objective is for the defender (sheep) to reach a certain destination on the board, the square of nine holes marked with red, and it is the attacker's (the foxes) objective to stop the defender from reaching it. The foxes are placed in the corners on the bottom of the red square (the paddock), whereas the sheep are placed on the opposite side of the board. When the players have decided who will move first, they move one step in turns. The sheep may only move forward or sideways, while the foxes may move in any direction, even backwards. If a sheep is in front of an empty hole, the fox has to jump over and capture the sheep, as in checkers. The capturing is mandatory, as are repeated jumps if possible. The sheep have won if they manage to fill the paddock, the red square.
