With a little creative thinking and the materials in your own house, you could make your own board games. Just follow these steps.
Make up a theme for the game. It could based on adventure, business, family life or something else. The object could be to reach a goal before the other players, or to eliminate them in some fashion.
Create the rules of the game. Write them down for your players to study.
Design the board on paper first. Decide how many spaces will appear on the board and what will happen on each space. Make sure you have an evenly divided number of good and bad things that happen on the board.
Make the actual board itself. You can use many dfferent types of materials, from cardboard and paper to finished wood and cloth.
