Best Ideas Game
This game uses a problem solving technique called "random presentation," and might even lead to some good money-making ideas. First, have someone look out the window or around the room and choose any object at random. Don't put any restrictions on this. It can be a rock on the side of the road, a stick laying in the yard, a truck, or anything at all. Now everyone in the car or room can try to come up with the best way to make money with the chosen object. A street sign becomes a place to advertise, and trees are to be sold door-to-door. A truck can be used in a hundred ways to make money, but look for the best new way for the sake of the game maybe a traveling grocery store? There is no winner or loser in this game. It is just an opportunity to let your imagination run wild, and to exercise your creativity. You may get a few laughs out of it too.
Concept Combination Game
Another good problem solving game for a group involves using a specific creative thinking technique, called "concept combination." You basically take two concepts or objects and combine them in some novel way. As a group game, the point is just to see who has the best idea. What can you come up with from the combination of a chair and a microwave? Perhaps an easy-chair that has a cooler and microwave and television built in. Or microwaveable "couch potatoes" - a potato snack in the shape of a couch.
Change Of Perspective Game
You can also try the "change of perspective" technique for problem solving games. One way is to just take a topic ranging from morality to having a job, and see who can come up with the most unique (and perhaps coherent) new perspective? Could there be a world where there were no jobs? What would morality be to a virus if it had consciousness? Once again, there are no losers in this game, or any of these types of games. It is just a chance to get creative and work that mind power. You could vote on the best idea if you want some sort of score keeping, but either way you'll enjoy these problem solving games.
