Here you see printed instructions on how to play my daughter's "Marley and Me" board game. She made game cards from recycled cardboard (you could recycle old game cards also), and she recycled dice and game pieces from games that were heading to the trash can. Instead the game pieces found a new "home".
Here is a brief introduction of her newly created game. It is pasted to the back of the game board (folded).
My daughter recycled a game board from an old game, and pasted her own onto it.
So don't throw out your old games even if they pieces are missing. Keep an area in a closet or garage for recycled items. You never know when you will need them or use them for another use.
