A 52 card trick Logic puzzles  Weight: 5 Liked the puzzle: 100% 26.12.2009
A famous magician takes a standard 52 card deck and gives it to the audience. The spectators choose any 5 cards (they may do it any way they like) and pass these cards to the magician's assistant. The assistant announces 4 of these cards out loud. The magician responds by naming the fifth card. Except for the suit and denomination of each card, the assistant passes no other information to the magician. How does the magician "know" the fifth card?

is it safe to assume that the audience retains the remainder of the deck (it doesn't say that they give it back) and that the magician has no way to spy on the selection process?

Isn't this the answer? : "Except for the suit and denomination of each card, the assistant passes NO OTHER INFORMATION to the magician."

to quote: "the <b>spectators</b> choose any 5 cards and pass ... to the assistant" - it does not mention what the spectators do after this, only the assistant himself. But I'll take that as a "they don't share any info either".

"passes no other information to the magician" does not equal "only tells the magician except for the suit and denomination", the order in which he reveals the first four could have been agreed upon before hand to tell the magician the 5th card.

If I understand you correctly they are equal..
