Hi,

I'm asked to perform at a charity event that is casino themed. I want to create a give away for every guest. Something that can be printed on a single sheet.

The only idea I have for now is the trick with playing cards glued together where they have to place a paperclip on the middle card. You know, like this one: https://www.youtube.com/watch?v=cB5d7zFh-PA

Can you think of anything else that is casino/gambling/scam themed that is easy enough for the visitors to understand and perform?

Thanks!

Update: lucky number guess... or psychic roulette with age cards might be a good one as well.
