3-tiered Decision Wheel with Decoder Ring. Set the secret code letter to equal a number that only you and your friends know (e.g. A = 10). Then leave secret messages on the chalkboard that just look like a string of numbers until you turn the number wheel and write the correct letter underneath. Or, ask the Oracle a question and spin the center wheel:  will the answer be Yes, No, Maybe or Later? 
Colors: Multicolored (as seen).
