To solve this puzzle, it involves a magic trick. To complete this the card trick, you will need to get a standard deck of playing cards.
Start by arranging nine playing cards on a table exactly like the layout in the image below.
Now, freely choose and place your finger on ANY one of the cards on the table. Spell the number or name of the card (ignore suit) you have chosen, moving your finger from card to card, moving once for each letter. (e.g. For the card with the Five on it, count out F-I-V-E, for a total of four moves). Do not count the space you start on. You may move left, right, up, or down, but NOT DIAGONALLY. Keep your finger on the new card.
I have magically determined you are not on the Seven of Spades or the Ten of Hearts, so please remove them. Now from this position, move your finger, as usual (horizontally or vertically), SEVEN times to any remaining cards you wish. Keep your finger on the new card.
With my amazing abilities, I see which card you are touching, so take away the Four of Diamonds. Now move your finger NINE times. Keep your finger where you stopped.
Now remove the Queen of Clubs and the Eight of Hearts from the table since you are not touching them. Now move your finger FIVE times to any cards remaining. Moving the same as before. Keep your finger where you stopped and remember the card. Now, you started where you wanted and moved where you wanted. But even though you are at a computer an unknown distance away from mine, I know exactly where you are.
