Topic: Single Die Con 


I saw this done at a Renaissance Faire a few weeks ago and I'd like more information about it. A fellow was walking around with a large (maybe 6inch), wooden, 6sided die. He'd find someone to play against. The rules: He rolls the die (in the grass or dirt) and the topmost number begins the running total. He and the mark take turns moving the die a quarter turn, adding the new topmost number to the running total. They share the running total. As I recall, he even gives the mark the option of going first or second. The winner is the first person to move the die to expose a side that brings the total to 30. The guy never lost. I imagine the winning strategy involves making sure you hit the total of 23, so the mark can't hit 30, but you can hit 30 after that. Anyone know the name of this game or how it works? 


The 31 game by IMHO Dr. Jacob Daley (I'm not at home). Pass me your emailadress and I will send you at saturday more information. HansChristian 


Hi, Dr. Jacob Daley converted in 1945 the well known con game "31" to a con dice game. I own articles from the german magic magazine "Magische Welt": WGR: "Dr. Daleys Würfeltrick"; Magische Welt, Nr. 10/1959 and eastgerman magic magazine "Zauberkunst", Hanns Thielemann: "Dalays 31System"; Zauberkunst 1983, Nr. 1, p.42. Ken de Courcy IMHO also published about the game.  Primary key numbers (reached by 1  6): 4, 13, 22. (It's digital root is 4) Secundary key numbers:  Reached by 3 or 4: 5, 14, 23; 9, 18, 27; 10, 19, 28.  Reached by 2 or 5: 8, 17, 26.  Reachesd by 1 or 6: 30 To win: The first player must start with 4 else he can loose.  Dr. Rhode  an eastgerman magician  submitted in the 19sixties his system. He deals only with key number higher 20. The key numbers are 22  23  26  27  28  30 22: reached by 1  6 23: by 3 or 4 26: by 2 or 5 27: by 3 or 4 28: by 3 or 4 30: by 1 or 6 (a little joke) Kind regards, HansChristian 


Amazin Doug wrote: "The winner is the first person to move the die to expose a side that brings the total to 30." This is not the same as in the original: The winner is the first person to move the die to expose a side that brings the total to 31. On the other hand a person loses with a total more than 31. 


Mark Elsdon has a version done with an imaginary die in his Conversation as Mentalism booklet vol 1. 


Hans cristian thank you very much. this is a great small quick little game. 


Just a heads up for anyone who is interested: Dr. Daley's original writeup is in Gibson's The Conjurors' Magazine Vol. 1, No. 2 (March 1945). 


I'm interested in this but I'm being a bit thick and so having trouble understanding the explanation! If anyone would be good enough to spell it out for me or point me to a resource that's readily available online, I'd be very grateful. Thanks. 


Neil: Check this out from Viking Magic. It is based on this principle. https://www.vikingmagic.com/product/automatic31zimmerman/ 


I would like if someone would confirm whether the 31 die trick is referenced in Learn Magic Cyclopedia . I had written notes that I think came from this reference. Thanks if can confirm or not. 


Sounds interesting 


Anyone have any other information on this? 


MAGIC magazine Volume 9 number 2 ,1999 Oct. page 90 Flim Flam by Farmer. Has a reference about this and I am looking for a copy to verify.

[/quote] there is a version in this magazine but its slightly different. instead of the die being turned one quarter turn to whatever exposed side there is , the player is allowed to play any number EXCEPT the number just played by the mark example: mark plays 4, you can play1,2,3,5,6. there are 4 specific "magic numbers" that are talked about. definitely easier to remember and follow.
