Objective: gain penalties - as little as possible - by flipping a rotor through a gate
Build up a gate on a table - flanked by a skittle and a backstop on each side. Use a curved needle to flip the rotor through the gate to opponent's side - avoid to hit a skittle/backstop; otherwise collect a penalty and try again. First player gaining 20 penalties has lost the game.
Note:
This game was invented in Germany before the Second World War. Based on the tools/materials used, one of the possible German publishers before WWII could be Edwin Mieg oPH (Mieg).
