Abstract: A game apparatus for two or more players, comprising a playing board having horizontal ranks and vertical rows forming an array of playing squares, with four sets of playing pieces, each set having distinct indicia disposed upon the front face of the playing pieces, with a border surrounding the array of playing squares on the playing board, and four distinct indicia similar to the indicia on the front face of the playing pieces disposed on the border of the playing board adjacent to each rank and row. There are at least as many playing pieces as there are playing squares in the array, with extra playing pieces withdrawn from play prior to the start of each game. Each player selects six playing pieces, and places one playing piece anywhere on the playing board, selecting a new playing piece from the drawing pile upon completion of each turn. Play alternates between players, until all the playing pieces have been played, without matching any indicia on any of the adjacent squares or adjacent border indicia.

Abstract: Improved quality of sound perception and discrimination in a self-powered, ear-mounted hearing aid is accomplished by pivotally mounting the sound inlet passage for 360.degree. rotation in a plane parallel to the ears of the wearer.
