A drive unit of a carriage has a drive wheel and a deflector, offset parallel to a racks both of which are implemented as gearwheels, around which a closed elastic toothed belt with teeth on both sides is guided, whose inner teeth engage with the wheels described and whose outer teeth engage with the rack. The first Coriolis element may be driven to a first vibration along a second direction which is parallel to the main plane of extension. A game progressing section causes the game to progress according to the instruction operations.
