I have an mgm grand room key number 1717 - this is one of the original types of room key that is a real key before they all started going to the key card entry.
It has number 1717 engraved on one side for the room number. Looking for suggestions of a good way to force that number via a math elimination or ....
Have the story and patter all routined out, just can't figure the best way to force that number and have it appear fair and random. Any thoughts or suggestions?
thanks!

I just started messing with a matrix force( With cool input from the Smarties) and they are pretty fun and easy too!
