Animal See-Saw

Animal See-Saw is a game for two players.

Each player is given 12 animals.

Players take it in turns to place an animal on their side of the see-saw - making sure that their side of the see-saw is never more than 5 kg heavier than the other side.

The winner is the player who survives the game without ever being more than 5kg heavier than his/her opponent.

If a player does become 5kg heavier than their opponent, the see saw falls, they lose and the game is over.

If both players make it to the end of the game, the winner is the one with the most weight on his/her side.
