Abstract: A parlor game is played on a mat having a rectangular playing panel on which a playing field is marked and a pocket located along and extending from one margin of the playing panel. Along its margins, the playing panel is fitted with stiffening bars which have their ends mitered to conform to each other at the corners of the panel. The bars, when the playing panel is spread over a supporting surface, maintain the panel in an open condition and prevent it from gathering when playing pieces are moved over its playing field. These playing pieces fit into the pockets when the game is not in progress. While the mitered ends of the stiffening bars are adjacent, they are nevertheless detached, and this enables the playing panel to fold along diagonal lines that pass between the mitered ends of adjacent stiffening bars.
