LED Tic-Tac-Toe

I built a Tic Tac Toe game. The game objective is to beat your opponent by getting three in a row. In the wiring diagram shown below (Figure 1) it shows buttonSelect and buttonMove. Players will use buttonMove to move the cursor, which is displayed as a fast-blinking LED, to the LED they wish to select. The players will then use buttonSelect to lock in their move. If the game ends in a tie their moves will continue to display. The players can choose to reset the game with the on-board reset button and play again. If a player gets three in a row the board will clear itself and start to display a wave-like motion to congratulate the winner. A live demonstration is shown here: https://youtu.be/MPrFotFDdpo
