Microelectronic Systems--University of Tennessee 2 2 Background One of the oldest games known to man African and Asian societies play this game as a form of chess Some alterations made to original rules to make compatible with FPGA board.

Microelectronic Systems--University of Tennessee 3 3 Background Goal: –Capture more seeds than opponent. Original rules: –Select hollow on your side of the board and sow seeds around board until you run out. –Place seeds in your home but skip opponent’s home as you pass by. –After first player releases last seed - second player’s turn begins. –If player runs out of seeds on their side of the board then game is over and the other player receives all seeds left on their side.
