Players must prove their adeptness at somersaulting bulls. They do that by performing the somersault in five steps.

Left and right horn stones of varying colours and values are used in a type of Memory game to collect matching pairs of horns. These pairs symbolise the height of the somersault. Higher values mean greater skill.

Players can challenge each other by trying to throw a ring over one of the horns of a bull sculpture.

Victory goes to the player who has the highest jumps at the end of the game.

Content of the box :
- 50 playing stones and 1 horn sculpture made of THETA stone
- one leather ring
- one rulebook
