How to shuffle lists and run a lottery using just a pen and paper

We used to determine first player in games by having one person pick a number and one person pick a player (writing each secretly on paper or flashing some fingers to a third party as a commitment scheme). You'd then count that number of spots from that player.

This sort of "randomness through unwitting collusion" reminded me of that.

(Admittedly, shuffling an entire list seems fancier, like you're getting much more work out of it.)

I used to love playing Amidar. I can still sing the tune.

(The guy who is playing in the attached video is an awesome player!)
