Jewel of Truth is a boardgame version of spin-the-bottle, designed for young girls.

From the manufacturer:

"Jewel of Truth will expose your innermost secrets and reveal your future! If the Jewel of Truth points to your colored jewel, you must reveal a secret, while other players try to
guess what you will say. When players match your answer, you both earn fortune cards."

There are five types of fortune cards; each player may hold no more than one of each type. The first player to collect five fortune cards wins.
