The magician talks about the game Three Card Monte, where there are two matching cards and the player must follow the odd card.
Then he explains that he"ll show a version with more cards, 8 equal (jokers) and one odd (6 of diamonds). When the spectator bets on the odd card, it is now shown that this card is a joker and all the other cards have become the 6 of diamonds.
Everything is examinable at the end.
This is a version of the effect "Incauto Tramposo" created by the Spanish magician Pepe Carrol.
