Clearance of the company to plates of a checkerboard sliding.

摘要

This parlour game is composed of several plates, which may be fixed or sliding, or all sliding, positioned so as to be parallel and flat on a base. On their upper face, they have a certain number of different, coloured squares arranged in a checkerboard fashion and over which magnetised pieces are moved. Some of these plates can slide between others which are fixed, all of them having an identical width but the sliding ones being longer than the fixed ones. The sliding plates are modified after each movement of a piece by one or other of the players. The magnetised pieces located on the squares of the sliding plates remain at the location given to them for as long as the said plates slide. IMAGE
