Nine men's morris set suitable for travel and the blind

摘要

Blind people can conveniently use this game, since the pieces, which are provided with steps, slide securely in guide tracks and engage into the playing board at the intersections and at the decisive points, the piece being guided by a single finger and the finger being able to identify, by a projection in a recess in the piece, whether the piece in question is white or black. This game is also suitable for travelling, since the pieces cannot slip and no playing table is needed. The pieces are so designed that they can be plugged into one another so that they require little space for storage, which is provided in holes in the playing board. If the playing board is made from wood, a new, circular layout of the lines in place of the familiar rectangular playing plane is advantageous for production, turning instead of milling, and also a saving in material.
