This an example of a puzzle that a CK can use to stump his players. It can be placed anywhere you need it, usually securing a door or chest from intrusion. This puzzle should be considered easy to medium in difficulty.

Read the following out aloud to the players:

“You see before you a closed door.  In front of the door is a pedestal with twenty numbered buttons on it. Below the buttons an inscription reads:

Nine Prime
All the Pairs
Two Sets of Three.”

The solution to the puzzle is three distinct steps, each described by the lines in the inscription. As each of the buttons is pressed, they remain in place unless a mistake is made, in which case the buttons all reset themselves.

Nine Prime: Press the prime numbers (1,2,3,5,7,11,13,17,19)

All the Pairs: The remaining buttons that are multiples of two (4,6,8,10,12,14,16,18,20)

Two Sets of Three: the final two buttons are 9 and 15 (both are divisible by three, hence sets of three)

This puzzle should not be too hard to solve through trial and error or process of elimination.  If you feel the PCs need a little extra pressure, then you can set a consequence for them if an incorrect button is pushed.  For example, maybe the person pushing the wrong button is shocked for an appropriate amount of damage.
