Cipher Wheel
The cipher wheel has two parts and each part can be hidden or locked away separately. One part displays the alphabet and the other part shows numbers 1 through 26. When a players lines up a specific number with a specific letter, a code of numbers can be deciphered into letters/words and vice versa.
Ideas
- Letters can be found that provide numbers to open a padlock.
- Letters can be found that provide numbers to find a book by call number.
- The first letters of a book title can be used to provide numbers.
- Numbers can be found that provide letters that spell out a title, and wait for it, the title could be used in the card catalog where a special note was attached to the MARC records, giving them another clue.
Black Light & Invisible Ink Pen
Use the pen to give “invisible” clues to be found when the players find the black light.
