Mensa 3rd Graders At Recess
There are dozens of variations of this puzzle type, but I put my own spin and characteristics to it.
It is lunch time for the little ones at Mensa Mini's Private School. The children have come up with a unique, fun game that will involve them all.
There is a stack of index cards cut into quarters, one side blank - the other side has the name of a color spelled out. Each student chooses a card, face down, so they do not know what they chose. They then apply a piece of tape to the back and adhere to their forehead.
Outside they sit in a circle. Each student can see the others' card, but not their own.
How would these little geniuses go about figuring out their color, and leaving on the next tune played? How would these little Einstein's figure out what color is not theirs? Putting yourself in the place of one of the students, let's see your logic to get out as a winner!
The teacher explains the rules.
1. The teacher will play a tune by hitting a musical triangle at constant, regular intervals.
2. The moment a student knows the color written on his card, he will leave on the next triangle note. If anyone is wrong, they lose and go inside.
3. The teacher explains that the game is not impossible.
Hint #1: Colors appear more than once. If they didn't the kid with the color would never know.
Hint #2: If a kid sees only one of a color, he can assume he is wearing the same color.
