Christmas crackers - probably a UK/Oz/NZ/SA etc Xmas thing - a bit like a fortune cookie that goes Bang when you and another person pull it, frippery falls out of it and usually a week joke and you can't eat it. Joy has used the musical type Where the each cracker has a whistle and a number. The conductor has to read music by numbers and point to the number on the whistle which is then blown. Instant music (not).

However she want something different - I thought what about Bingo. Number inside each cracker and cards dished-out before you start. Over quickly so everyone joins in.

Any one ever seen such a thing. Otherwise I will make them myself. Probably needs a lot of cheap crackers, contents unimportant, I will slip the numbers in myself. Don't need 100 numbers and cards would have to be suitably truncated. But how to run the permutations (Oh OK combinations) to Guarantee one winner? 12 - 20 players.

Ideas anyone?

I could do a Montecarlo analysis in VBA in a spreadsheet but it is not my forte. And it would run and run and run. The iterations worry me.
