No supports needed, for pieces I printed with a brim and then used a knife to cut it off, but it could probably be done without one with a good base plate, feel free to take the logo off the center of the board I just used it for fun to spice it up. You will need to print the pieces 4 times (in different colors, or paint them or something) and the 2edgeboard twice to have all four edges. If you don't know how to play just google the rules to otrio its basically suped up tictactoe.
