Calculator Cards credit

Discuss the historical aspects of magic, including memories, or favorite stories.

Can someone please help me by knowing who is credited with coming up with the 'Calculator Cards' trick? This is the one with 6 cards and whichever ones have the thought of number on them, the numbers in the top corner add up to it.

Thanks for any help or pointers.

It used to be called "What's your age" trick and seems to have become popular in the 1970s.

Whaley's Encyclopedic dictionary of Magic says the jargon "Age Cards" was in use by 1931 having appeared in Douglas catalog #16.

Also, in 1910 Theodore L. DeLand adapted this principle as the method for his Million Dollar Mystery card trick which was rel (where a spectator thinks of one playing card; is shown several boards with different sets of playing cards pictured on each; answers "yes" or "no" as to whether the chosen card is on each one; and the performer then divines the chosen card.)

it seems that Dan Garrett have a trick named Cyborg in his book Garrett Does the U.K. Lecture Notes 1991 which looks like ''Age Card'' but as I haven't this book, you have to check.

The Age Cards are in "Mathematics, Magic and Mystery" (1956). Martin Gardner says he doesn't know exactly but thinks it must be one of the oldest mathematical tricks. Early books on mathematical recreations (e.g. Bachet's "Problemes plaisans et delectables", 1612)) contain a lot of stunts like this, so it could well go back quite a long way.

Hi Edwin,

Is it Guessing Someone's Age, page 166 ?

Thanks guys. I had a feeling it was really old but wasn't sure if it was traceable to someone in particular. I'll still be making enquiries around...

I see references that it's supposed to be in Charles Hutton's Recreations With Mathematics (1801)

It's available in Google Books if you want to try and look for it:

The " impenetrable secret", an effect where the spectator thinks of one of a hundred preprinted sayings from among ten cards, was the earliest magic "imprint" produced in the us, having been printed on franklins press itself. (1749)

The trick was advertised in the London daily adviser in 1747.

Gardner calls them Number Cards (page 95). He goes on to mention the more elaborate variant known as Window Cards, which are also described in Rouse Balls Mathematical Recreations and Essays. The latter has been through many editions since its first publication in 1892, but the window cards are definitely in the 10th edition of 1922.

Cyborg in the Dan Garrett lecture notes is a card location. You have the four 10s and deal more cards onto each one, counting back from ten to zero until the value of one of the dealt cards matches the number youve reached. Its similar to Twisting the Plot in The Classic Magic of Larry Jennings.

In case i wasn't clear, these cards use the same principle. Rather than being a direct number revelation, the cards coded the chosen proverb. Punx issued a set of 'psycho bell cards' which were closer to the impenetrable secret. than most number centric versions.

In the Magic Cauldron No. 45 (October 1972), Edgar Heyl says that the method made its first appearance in London in Nicholas Hunt's "Newe Recreations" (1631).

Edgar Heyl also has more of information on the "impenetrable secret" cards (with same information Brad has given above) in Cues for Collectors, No. 12, CARDS FOR CONJURING, originally published in MUM, July 1954 (and later as a collection in the book Cues for Collectors (1964)).

I just found a couple of developments of the principle in Karl Fulves' "Self Working Number Magic", pages 19-27. There's the basic version, then one where you also determine the day and month of the spectator's birthday, and finally a cunning Robert Neale idea using cards with words on.

Many tricks based on this principle are seen in various Japanese books that were published in 1600s, and even in 1500s as well.
Those have never been explained in western countries.
I wish to explain them some future.
