NUMBERS GAMES

Internet Gambling

Information about cards that you're not supposed to see can create an unbeatable advantage in poker.

Millions of people around the world are being fleeced on internet gaming sites due to collusion. The sites all advertise that they have software that catches the patterns and bans the cheaters. The software detects the players that never go up against each other. Over time it does work if the team is only relaying information and fending for themselves. If the cheaters create a syndicate that shares all profits, then they have no fear of going against each other and cannot be caught. The penalty for being caught is getting kicked off the site. There are hundreds of sites with new ones being added daily. They do not share cheater information like Las Vegas casinos so it's not much of a penalty at all. Internet gambling has surpassed pornography as the number one moneymaker on the worldwide web. Expect this scam to grow.

All Numbers Lead to the Same One
This "number stunt" is one of the oldest and best.
My father learned it from his father. No matter which number the volunteer chooses, the answer will always be 1089.
Secret: Here is how it works: Ask someone to write a 3-digit number and to reverse it. He has to subtract the small number from the large one. He then reverses the new number and adds the two together. The final total will always be 1089. Let's say he chose the number 851: 
851 - 158 = 693 + 396 = 1089 

If the first equation is 99, it has to be added to itself before continuing the calculation. For example, if the first number he chooses is 150: 150 - 51 = 99 + 99 = 198 + 891 = 1089

The 99 Presentation:
Tell him: "Write a 3 digit number, reverse it and subtract the small one from the large one. Now you have a 3-digit number, reverse it and add them together."
If the volunteer says that he only has a 2-digit number (the 2-digit number will always be 99), tell him: "OK, let's make it a bit harder. Whatever number you have, add it to itself. Then reverse the answer and add the two totals together." His final result will be 1089.
Knowing 1089 is always the answer can be used in many mind-reading feats.

My Favorite 1089 Force: 
Get prepared ahead of time by memorizing the tenth word that is on page number eighty-nine of a chosen book. When the person gets to the final total (he doesn't know that you already know the number is 1089), give him the book and ask him his number. Say: "Since the last two digits of your number are 89, go to page 89; and since the first two digits are 10, go to the tenth word."
Right when the volunteer is about to read the word, you say it aloud as if you were reading his mind.

Repeated Number
Tell someone to write the number twelve million three hundred forty five thousand six hundred seventy nine on a piece of paper: 12,345,679. This long number represents each digit except 8, so it won't be hard to memorize.
Ask him to circle the number that he thinks is his lucky one. Let's say 5. Mentally multiply the chosen number by 9 (5 X 9 = 45). You then ask the person to multiply your total by the long one. (In our example 45 X 12,345,679 = 555,555,555). The result will be a long series of the lucky number.
This works with each number, even 8.

100 to 999
Here is a simple "mind reading" game that you can do anywhere.

Hand a piece of paper to a volunteer and ask him to write a number between 100 and 999, without showing it to you. (Let's say he chooses 643). Proceed by asking him to reverse the number and to subtract the small one from the large one. (In our example 643 - 346 = 297). 

Then ask the person the first digit of the final number. (In our example it is 2). After a few seconds of "concentration", you will guess correctly the final number.

Secret: The final results will always be: 99, 198, 297, 396, 495, 594, 693, 792, 891.
Once you know the first digit, it is very simple to guess the full number because if you add the first and last digits you get 9, which is the middle digit.
The only exception is if the first digit given is 9, that means the number is 99.

Which Day is it?
Ask someone from the audience to give you a date. With some calculation you will be able to guess the exact day of the week the date falls on.
To start, you must learn a code that represents a number for the months, and a number for each day of the week. 
Month Value
June 0

September, December 1

April, July 2

January, October 3

May 4

August 5

February, March, November 6

Note: In Leap Years, January and February values are reduced by one. 

Day Value
Sunday 1

Monday 2

Tuesday 3

Wednesday 4

Thursday 5

Friday 6


Saturday 0

As an example, the date given to you is May 5th, 1844. Take the last two digits of the year (44) and add a quarter of it (11) which totals 55. Then add the value of the month (4 = May) which gives 59, next add the day of the month (5th) giving a new total of 64. Divide this new number by 7; the remainder will be 1. 1 represents Sunday. May 5th 1844 was a Sunday.

If the last two digits of the year given by a spectator cannot be divided exactly by four, then take the closest lowest number divisible by four.

For example, let's take the year 1838. We use 36 as the closest lowest number that we can divide by 4. Then add a quarter of 36 (9) to 38 giving 47 to which the value of the month is added.

This example (May 5th 1844) applies for the nineteenth century 1801 to 1900.  When the given date happens to be in the twentieth century 1901 to 2000 subtract 2 from the last remainder; when the date is in the eighteenth century (1701 to 1800), add 2 to the last remainder.

Let's Recap:

Add the last 2 digits of the year to its quarter.

Add the code value of the month.

Add the date of the month.

Divide the total by 7.

The remaining number represents the day of the week.

Subtract 2 from the last remainder if the date is in the 20th century. Or add 2 if the date is in the 18th century.

Other Examples:

June 18, 1921: Add 21 to 5 (quarter), plus 0 (month), plus 18 (date) equals 44. Divide by 7; the remainder is 2. Subtract 2 for twentieth century = 0. 0 represents Saturday.

October 4, 1718: Add 18 to 4 (quarter), plus 3 (month), plus 4 (date) equals 29. Divide by 7, the remainder is 1; add 2 for eighteenth century. The number is 3 which represents Tuesday.

You can impress people by guessing the day of their wedding, birth, and so on.

Date Prediction

The medium holds two pocket size calendars. He hands one along with a pencil to an audience member, and keeps the other. The performer tells the volunteer to choose a month and to circle one date of the chosen month without showing it to him while the performer does the same.

The volunteer is then asked to say the date and month he chose. The medium shows him his calendar which has the same date circled.

Secret: The effect is done with a thumb tip writer. When the person is asked to circle his date, the performer pretends to do the same with a pencil. Once he hears the date, he circles it with the thumb tip.

The same principle can be applied with many other feats of mentalism. The thumb tip writer provides an endless list of predictions and lots of fun.

Easy Mental Arithmetic

Ask an audience member for a three-digit number that you write twice on a black board. Let's say 391.

  391          391

Then ask him for another three-digit number that you write under the first one that serves as a multiplier. Let's say 748.

  391          391

x748    

And last you write a three-digit number under the second one that will also serve as a multiplier. Let's say 251.

  391         391

x748       x251

Now you tell him that you can mentally do the two multiplications, add the two results together and come up with the total faster than he can with a calculator.

Secret: When he gives you the second three-digit number, (in our example 748), subtract each digit from 9 and write this new number as the second multiplier (in our example it would be 251):

  391      391

x748     x251

While the volunteer is busy multiplying and adding, you subtract 1 from the first three-digit number, and write down the result. (In our example it will be 391 - 1 = 390).

Then subtract each digit of the last result from 9. (In our example subtract the digit of 390 from 9 which gives 609).

You now write this last result (609) to the right of the last number (390) and you get the final total. In our example the final total is 390,609.

This can be done with any three-digit numbers if this formula is applied.
