How is this possible? Figuring this out is the challenge that makes this puzzle so interesting.

Great Little Card Trick
Emawk05

What a great little application; quite fun to reason about how it works under the covers. Once you figure it out, it’s endless fun to play the trick on the mathematical inclined.

Feeling deceived...

The premise behind this trick is awesome. It's a great idea. There's a slight problem however - it doesn't work (at least, not as described). Supposedly you can have someone select five cards either by choice or by random. The magician selects one of the 5 cards and the spectator inputs the other four cards into the iPhone. When the "Guess" button is pressed, in theory, the one remaining card (chosen by the magician) should be revealed. I fiddled with this app for a little over an hour. Here were my observations... I chose 5 cards at random. I selected one card to be the "unknown" and the other 4 were plugged into the iPhone. How the application deduces the 5th card is not clear to me at this time. Interestingly enough however, the 5th card was never properly identified. To make matters worse, depending on the order that the 4 cards are input into the iPhone will generate a different result for the guessed card, resulting in 24 potential outcomes - unfortunately, none of which resulted in the correctly chosen 5th card. For $2.99 I feel completely ripped off! Since the author has no intentions of giving away the secret, you're paying for something that you may or may not be able to figure out. A complete waste of money. This should be free and the secret sold for $2.99. If you want some truly good iPhone magic tricks, check out Hottrix' iBeer, iChampagne, iWater, iMunchies, iMilk or any of their other iPhone tricks. There's also Marty's Magic Coin and Marty's Magic Card. Both of those are DEFINITELY worth the $2.99 and you get the secret too!


Does not work!

This is a scam. The trick does not work. Why would the author do this to people.

Without the solution, this is not a trick, but rather a puzzle; one that is quite difficult - I might add. It should be described as such, and the solution must be made available - even if at an additional charge if necessary. Without the solution, it is simply worthless. PLEASE Where can I get the solution?


HORRIBLE

This doesn't even tell you how to do it! This is probably the worst app ever!!! Don't buy it it's stupid and a WASTE OF MONEY!!!!!!


Love this trick!
Magicbri

This is a killer little trick that will leave the know-it-all's out to sea! Took me more than a month to work it out, but well worth the challenge. I hope no one else dope's it out! My only beef is I would like a cooler interface. Thanks for this little gem, and definitely keep it a secret.


Terrible Magic Trick!

Beware this application is terrible magic trick! It is a puzzle but not a magic trick. My advice is to avoid this application. There are many fine magic tricks applications for the iPhone but this application in not one of those fine magic tricks.


A waist of money

The link to help you find the solution reads "Not Found." I have watched many app developers upgrade their programs to fit consumers requests. They seem to care. Where is this guy hiding. Either give us the solution or help us find it. It's not that had. That is what your buyers want. One guy figured this puzzle out. I'll give you one guess who that must have been. Make this a great trick and I will rate it a 5 star app.
