A brass canister, lid & die are examined. As you look away, a spectator puts the die in the canister, remembers the number on top, & covers with the lid. You turn around, concentrate, then write a number on a piece of paper. The lid is lifted, revealing the number on the die...it matches the prediction! No questions. No fishing. This clever device gives you all the information. You no longer need to turn the box over to discern the number. In fact, you don't even need to touch it! Manufactured in Solid Brass! Don't confuse Die-Cipher II with the various versions of Mental Die. This is much better! Die-Cipher II tells you the exact number selected!
