I agree with Dat above, gambling routines are very popular. I tend to use them more and more. I did a kids party the other week. They were all either ten or eleven years old and I used a gambling patter. They loved it (even if I say so myself), since it turned out that they were all regular blackjack players.
Yes! Even I had to read that twice.
You see I have two sets of patter for some of my routines. One is 'magic' the other is a gambling patter.
Mechanically the tricks are identical.
This gives me an opportunity to alter the patter as I see fit, according to how I think the specs will react.
It also means that I have, in a sense, twice as any routines.
Actually that's not true at all, really.
Farlsborough, are there any of your routines for which you can simply write a new gambling patter?
It does take a little imagination, although really any prediction or transposition efffect can be adapted.
