This Game is meant for Cub Scouts.

6 to 10 scouts.

You may find it goes better by using physical 'points' such as squares of paper or pennies.

Group sits in a circle. Every scout has 5 points. One scout is sent out of the room and the others decide what this scout is to be.
When he comes back, he asks each scout in turn, "What is in my shopping cart?"
Each scout names some item this person would need.
For example, if they chose a Fireman, he would need a hose, helmet, axe, gasmask, ...
As soon as the guesser thinks he knows the answer, he can choose to take a guess. If he is incorrect, the last scout that gave a clue gets one of his points. If he is correct, he keeps his remaining points, sits down, and another scout becomes the guesser.
The guesser MUST take a guess after having gone around the circle one time getting clues. Then, he must guess after every 2 clues after that, at a minimum.
After everyone has been a guesser, the one with the most points is the winner.
