The Inventors (1974)

Though the base mechanism is Monopoly-like (the object of the game is to amass the most money), the way this game plays is different. The theme of the game is that you are investors in various comically named inventions. The game has a very curious mechanism that does double duty for rolling the dice and applying Patent Claim clips. (The kids love fussing with it.)

The game board has an outside track, the Invention Track, and an inside track, the Royalty Track. On the Invention Track is where you pick up the various inventions (like buying properties in Monopoly). Instead of building house and hotels, you get a Patent Claim Clip attached to the invention card. This patent clip has a 0, 1, or 2 on it. The number assigned is random. The higher patent clip number, the more your patent makes you come royalty collection time. Eureka Cards can also be played that allow you to do special actions during your turn. The game limit is set by the usage of the Patent Claim clips. When the last one is used, the game ends. The player with the highest combined total of cash on hand invention value wins.
