Design your game board. On foam core or cardboard, design your game board using Crayola Erasable Colored Pencils. Include the start (perhaps an entrance to a mineshaft). Make the game path, which could be a track for mine carts that go deep into the mine. You’ll probably want at least 40 spaces along the path through your mine. Add trick sections such as loops, pools of water, or avalanches (dead ends). Remember, you can easily erase the colored pencils if you change your mind.
