Basic Tic Tac Toe game. Flick the levers to put a piece on the board. Get three in a row to win. I used alot of redstone, repeaters, and slabs. I used NOT gates to make sure things work properly.
Stand on the platform in the front. Pick a side, left for O's and right for X's. If you want to put your piece in the top left corner, you have to flick the top right lever, and if you want to put your piece in the top right corner, flick the top left lever. Just flip the lever on the opposite side of the row put get it there. Left is right, right is left, middle is middle. Get three in a row to win!
