Abstract:

A game board has playing pieces. In the form of indicators which are permanently attached to a game board base. A push button approach that simulates the play of well known games is used to effectively move pieces around a game board. The indicators are push buttons that can occupy either of two positions. In the up position the indicator could represent the presence of a piece or player, or that a particular location or region is occupied. The number of push buttons use will depend on the game and its rules. There could be one, two or four push buttons for each region. One push button could simulate the golf tees of a peg board game. Two buttons could be used to simulate a tic-tac-toe game, while four push buttons could simulate a checkers type game. The permanence of the indicators means that pieces cannot be lost.
