Step 1: Get a Friend
Optional: Have them shuffle the deck themselves!
Step 2: Lay the Cards in 3 Columns
First, lay the top 3 cards in a row from left to right. (picture 1)
Then add a second row on top the first . (picture 2)
Continue adding rows in this manner until each column has 7 cards. (picture 3)
Step 3: Identify the Column
Without changing the order of the cards in this column, gather it into your hand face down, followed by the other two columns on top.
Note: The order of cards in the other two columns no longer matters.
Step 4: Again and Again
Repeat a third time.
After the third time doing this process the card your friend selected will be the last card in the column they chose.
Memorize this card!
