Visit your local hardware store (I went to Menards) and get paint samples for free. I usually pick up two of each sample so that I can use one for the game board and the other one I use to cut up to make the matching game pieces. This cost me nothing to make and the kids love it. I usually talk to the paint department to ask if it is ok to take some extra samples for my family child care program and they are always more than willing to help me out. I glued an envelope to the back of this sample so that I could store the game pieces inside.
