Game of logic for one person - has masters placed blind in base and combination deduced by manipulating slides and fall through balls

摘要

The game of logic is played by one person and comprises a base (1) with a recess (1c) on top. Masters (4) are placed blind in this recess and hidden by a hinged flap (1h). A slide (3) passes between the flap and base and this is used with another slide (2) at the opposite end. This latter has an aperture (2b) identical to the base recess. Additional masters (4a) are placed in the second slide, together with balls (5) fitting in holes. The combination is deduced from the balls falling through holes in the markers which are in alignment.
