Vintage Phenomenon Math Trick 1960's Adding Dice Game Magic Tricks

The trick is based on an earlier version called the Di-Ciphering Trick based on a math trick developed by Ed Balducci (1906-1988); a New York City magician and civil engineer by day. The “Di-Ciphering” trick consists of 5 dice cubes bearing a different 3 digit number on each face – 30 numbers in all. A spectator would roll the dice and the magician would quickly announce the sum of all the numbers.

An example roll of the dice is:

186 147 459 168 179

with a sum of 1139.

The method used to quickly calculate the sum of the 5 die of 3 digit numbers is:

Add the last digit of all of the numbers -> 6 + 7 + 9 + 8 +9 = 39

39 is the last 2 digits of the sum.

To find the first two digits of the sum take 50 – 39 = 11.

Thus the sum is 1139.

This will work with any roll of the dice.
