This is a color matching game implemented on the Nexys 3 Spartan 6 FPGA board.
For setup, use the USB port to upload the game through ISE and connect a monitor through the VGA port. Once the game is setup correctly, you should see a 4x4 gameboard on the screen. Use the buttons on the board to move around (btnU, btnD, btnL, btnR). Use the middle button (btnS) to select and reveal a card. You can reveal up to two cards at the same time. If the two cards are of the same color, then you will eliminate a pair. The 7-seg display tells you the number of cards yet to be eliminated. You can always reset the game by using the slide switch closest to the buttons (T<10>).
Good luck and have fun!
