Boolean is an abstract strategy game that uses the concepts of Boolean Logic to play. At first created as a learning tool by College Professor Edu Jacober, Boolean was published in 2011 by Ceilikan Jogos. It is now out of print. Boolean is actually a game system and comes with two distinct sets of rules. The board represent a logic circuit with boolean operations that can be changed by playing cards on the game board. Basic rules: Players are either black or white (0 or 1) and, by setting the logic gates on the game board, try to get their team to score more points. In your turn you can: a) buy a card, b)play a card. Circuit inputs are driven by a FIFO line Advanced rules: Players are also either black or white and, by setting logic gates on the game board, try to get their team to score more points. In your turn you can: A) buy a card, b) play a card, c) feed a free input with a piece from your score track. Circuit inputs are copied from gameboard latches existent on more valuable locations in the gameboard.
