MASTERS OF LOGIC PUZZLES

MASTERS OF LOGIC PUZZLES - DOTS

Masters of Logic wanted to find out who was the wisest among them.  

So they turned to their Grand Master, asking to resolve their dispute.

"Easy," the old sage said. "I will blindfold you and paint either red or blue dot on each man's forehead. When I take your blindfolds off, if you see at least one red dot, raise your hand. The one, who guesses the color of the dot on his forehead first, wins."

And so it was said, and so it was done. The Grand Master blindfolded the three contestants and painted red dots on every one. When he took their blindfolds off, all three men raised their hands as the rules required, and sat in silence pondering. Finally, one of them said: "I have a red dot on my forehead."

How did he guess?

MASTERS OF LOGIC PUZZLES – HATS

After losing the "Spot on the Forehead" contest, the two defeated Puzzle Masters complained that the winner had made a slight pause before raising his hand, thus derailing their deductive reasoning train of thought. And so the Grand Master vowed to set up a truly fair test to reveal the best logician among them.

He showed the three men 5 hats - two white and three black.

Then he turned off the lights in the room and put a hat on each Puzzle Master's head.

After that the old sage hid the remaining two hats, but before he could turn the lights on, one of the Masters, as chance would have it, the winner of the previous contest, announced the color of his hat.

And he was right once again. 

What color was his hat? What could have been his reasoning?

MASTERS OF LOGIC PUZZLES – STAMPS

The Grand Master takes a set of 8 stamps, 4 red and 4 green, known to the logicians, and loosely affixes two to the forehead of each logician. so that each logician can see all the other stamps except those 2 in the Grand Master's pocket and the two on her own forehead.

He asks them in turn if they know the colors of their own stamps:

       A: "No"

       B: "No"

       C: "No"

       A: "No"

       B: "Yes"

       

What color stamps does B have?
