Algorithm for keycode

[papaburgs]

In order for a player to get a ball to go down the 'happy path', I want to have a pin that they have to enter.

• Want to make something that is dynamic
  • so its not like the skill testing questions for a prize draw where someone writes the answer on the box
• would like some sort of real world interaction (ie go to office B34 and find the number written on the white board)
• plan to have a 4 digit display where we can present a 'seed value'

First idea

• from that seed number and real world, the player does some math and comes up with the pin

Are there better ways to do this? Riddles, Puzzles?

settled on a bit of math, which should cause some issues with rounding and causing people to guess wrong.

then have some character swapping and truncation - hopefully be enough to cause some issues

need to type up rules and send to Don for printing
