How to play: You will take turns moving the red and blue pieces. You can rotate them, mirror them, do whatever with them as long as you place it in at least one new square or with no pieces overlapping the green tiles. After you've moved your "L" piece you can choose to move a black circle (if you don't want to move it just skip your turn). You can move the black circle anywhere you want as long as it's not where another L piece. black circle, or green tile is. Keep taking turns until the other player can't move! (Read the rules though)

Best out of 3?

Objective: Make it so the other player can't move

Rules:
You can't move a piece into a green tile. You can't place an L/black circle in the middle of two lines or rotated diagonally (you know what I mean), etcetera.
Red goes first because I said so.
You move the black circle after you move your L piece.
You can choose to move either one of the black circles (however you can't move someone else's L piece)
If you make the grid 3x3 it'll be too small to play and if you make the grid 5x5 it'll be too big to play (unless you adjust the sizes of some pieces)

Have fun!!
