Determine the type of game you wish to make. Family game options include trivia games, scavenger hunts, obstacle courses and guessing games like charades.
Add a theme to your game. Keep your game focused on family trivia or history or choose a topic you know your family loves. For example, if you are making a trivia game, focus the questions on a favorite vacation spot or TV show.
Create the questions, clues or guidelines for your game. For example, if your game is a trivia game, write several dozen questions and answers. Write the questions on note cards, with the question on one side and the answer on the other. For a scavenger hunt, create a list of items to find and make a plan for hiding locations.
Write scoring and play rules for your family game. For example, if your game is a trivia game, add rules for how players buzz in and how long players have to answer a question after buzzing in.
Set up your game, if necessary. If your game is a scavenger hunt, hide the items. If your game is an obstacle course, set up the obstacles.
Explain the rules of the game to your family.
