Card A 2-10 J Q K
Code 1 2-10 11 12 13
Suit Club Diamond Heart Spade
Code 6 7 8 9
In five steps given below, you can easily predict the unknown card! Let’s roll!!
Suppose your participant has an Ace of Spades, which you are not aware.
Step 1. Card Number Ace = 1 rows, columns and the diagonals is 2013!
Step 2. Times 2 1X2 = 2
Step 3. Add 1 2+1 = 3
Step 4. Times 5 3X5 = 15
Step 5. Add the suit 15+9 = 24
Prediction: Simply subtract 5 from above!
24 – 5 = 19, last digit = Suit and the remaining digits indicate the card, Ace of Spades!!!
In this number game, you can predict the three dice your opponent has rolled, which you are not aware.
Perform the following six steps and surprise your opponent:
Suppose the dice are 1, 3 and 6 in this order!
Step 1. First die times 2 1X2 = 2 rows, columns and the diagonals is 2013!
Step 2. Add 5 2+5 = 7
Step 3. Times 5 7X5 = 35
Step 4. Add the second die 35+3 = 38
Step 5. Times 10 38X10 = 380
Step 6. Add the third die 380+6= 386
Prediction: Simply subtract 250 = 386-250 = 136!
This trick could be extended to any three digit number 000-999!! Try!!!
