Abstract: Each player has a board having a number (N) of rows each of which comprises a number of sockets. The number of sockets in the first row is one, the number of sockets in the second row is two, the number of sockets in the third row is three, and so on up to the Nth row, which has N sockets. The game is played with a multiplicity of small pieces which fit into the sockets and which, when laid on a table with the proper orientation, reveal one of a number of N of first (or "visible") characteristics, such as color. Each small piece also has one of a number N of second (or "concealable") characteristics, such as color, which may be revealed or concealed, as desired. The small piece is constructed in such a manner that the first characteristic is always viewable whenever the second characteristic is revealed. The game apparatus also includes a die to determine the sequence of play, as well as a number N of small pieces which are wild. The game proceeds in major increments which I call "jousts".
