Ask Zandar Game - 1992 - Milton Bradley - Great Condition
The other players can make a "side bet" during their turn and guess at Zandar's answer. If they are right, they get a gem of their color. If they are wrong, they must return one.
There's a few other rules to the game, but that is main gist of it. The first player to place all six of their gems onto the game board wins and gets to have their fortune read by Zandar.
