Game for visualisation and memorisation of elements of geographic or historic interest

摘要

The game is a hollow case with an upper transparent cover (1) and a base (2). This is marked with a map of a country and has hollows (4) in its thickness which correspond to the main towns. Balls (6) are moved in the case to lodge in the hollows. The balls are marked with different numbers and must be lodged in the corresponding numbered hollow. The map can be replaced with simple designs and these can be marked on cards which are interchangeable. A rod and spring can expel the balls from the hollows.
