THE RULE Firstly, choose a number and save it in your mind. Then the magician will check the exsist of your number in six table by asking it to you.

KEY OF THE RULE Add all of the table’s title which it has your number. Then the magician can guess what number in your mind. Ex: My number is 8. Then 8 is in the 1st , 2nd , and 3rd table. So, the magician has to add all of the table’s title, that is 1+2+3=8.

GUESS THE BIRTH DATE

You can guess your friend’s birth date

• Here’s the steps:1. Ask him to multiply his birth date with

5.2. The result is summed with 6.3. Multiply it with 4.4. It is summed again with 9.5. Multiply it with 5.

6. Sum with his birth month. The month must be change in number. For example: January = 1

February = 2March = 3

7. For the last, ask him to mention the end of his result. So, you can reduce it with 165. Finally, you get it, which the result is the first of two-digit of birth date and birth month followed.

TRY TO GUESS THE REMAIN

DIGIT

The steps are: 1. Prepare some paper and pen. 2. Choose 4 random digits what you want and write down on

your paper, ex: 1, 2, 3, and 4. 3. Add each digit and keep the result for yourself. 4. Make the random digit that you choose to a number, ex:

you choose 1, 2, 3, and 4 became 4213, then subtraction with the result of 3rd step.

5. Mention the 3 digits from the result of 4th step randomly, ex: 4, 2, and 0.

6. Then I can guess remain digit that you haven’t mention it as soon as possible. That’s 3.

• Secret:When the audience mention 3 digits from

their result, add each digit and I’ll find new digit. Remain digit must be the nearest repetition from 9.

• Example:I have 4 random digits 1, 2, 3 and 4. Add

each digit 1 + 2 + 3 + 4 = 10. Then, we should subtract 4213 with 10 the result is 4203. The next step, mention 3 digits from the result, ex: 4, 2, and 0. In order to guess remain digit we should add the 3 digits that already mentioned 4 + 2 + 0 = 6. We know that the nearest repetition of 9 with 6 is 9, so we can subtract 9 with 6 and we find the result is 3. Now, we can guess the last digit that haven’t mentioned yet which is 3. That’s it.
