Go to [http://funkypages.com/cards/](http://funkypages.com/cards/)

Choose one of the doors. Then follow their instructions, you will pick a card and click on the button and the card you picked will be gone. I tried this in random patterns. Such as picking a certain position, or color…etc…

They haven’t failed once, how does this trick work?

_All_ of the cards are different (though similar), and there’s one less after the “trick.”

This was discussed here:[http://boards.straightdope.com/sdmb/showthread.php?threadid=13862](http://boards.straightdope.com/sdmb/showthread.php?threadid=13862)

It is a trick; the second set of cards is totally different than the first. No matter what card you chose, it will be missing from the second set.

Damn, not only was I not first (I’m never first); I screwed up the link.

:mad:

I just tried this website myself. Interesting. I wonder how they do it, perhaps it _is_ magic. 😉

It’s easy– **none** of the cards on the first screen are on the second.

Take door 2. Your primary choices are 9 spades, 7 diamonds, 8 clubs, 7 spades, 8 diamonds, and 9 hearts. Choose your card (say 7 spades). Click to the next screen… lo and behold, not only is the 7 spades not there, neither are 9 spades, 7 diamonds, 8 clubs, etc. Instead, there are cards that look similar to the original choices (7 clubs, 9 diamonds, 8 spades, etc.) but were, in fact, not on the list of original choices.

Pretty sneaky, huh?

Wow, i’m glad i’m not the only that was stumped on this damn card game. Actually had me getting mad at it for picking the right card each time before i calmed down and realized what was happening. 😃
