3 Card Monte –
Normally, there is no fair way to win this. Cartoon – it sounds like you actually played a legit game of 3-card Monte, which I’ve never seen in my life.
Generally, the drill is this:
Dealer shows you three cards, tells you to “follow the queen” or “follow the bee (in a Bee deck, Ace spades)” etc, etc, etc. Now, normally, he’ll let you win the first time, maybe even the second time, hoping you’ll be suckered into another double or nothing. Now the third time, what he does takes a bit of explaining. When he shows you the three cards in his hands, he’ll lay them down one-two-three cards down. BUT, he doesn’t lay them down in the order he showed them to you. He’ll lay 'em 2-1-3 is the way I normally do it, but depending on your sleight-of-hand skills you can do it any order you’d like. If you do it right, it’s extremely difficult to notice.
Also, another variation is the dealer has an accomplice, who plays the game and ends up either losing horribly (meanwhile, you’re watching thinking "Man, this guy’s a MORON! It’s card number 2 obviously) and you dive in, bet $10 and lose. Or the guy is winning, and you figure, man, this guy is just GIVING money away. Once again, you bet your bucks and you lose.
There’s often a third guy out in the periphery who’s watching for the police and gives a signal if there’s trouble coming that way.
Plus, please note the example I gave of mixing up the cards is only one of several ways to do this trick. I’ve also seen someone who squares up three cards in his hand, shows the “top” card, which in fact is the second one, resquares the deck and deals off the cards one by one to the table. Of course, you think the card to follow is the first, when in fact it is the second.
It’s a con game. You can’t win it. I’ve done it to my friends at bars for beer.
