As in La Fontaine's fable, players are frogs that wish to be as big as the ox. All players must simultaneously collect or give frog cards to other players. When a player thinks he has reached the size of the ox, the round is finished and players may be awarded. To win medals, the size of the frog must be as close as possible to the size of the ox. But if you are over the size of the ox, your frog bursts and you have to give away a medal. The first player to have 7 medals win the game.
