I have a disc from a Radio Wheel of Fortune game featured at one of the stations I worked at, which was a simple word guessing game. The descriptions sound close. This version was released by a firm called Media Leader, and it was a sponsor tie-in with Nexxus hair care products. There were three cuts for each weekday. The first was a produced cut with the theme, the opening WHEEL-OF-FORTUNE chant, an announcer doing a sponsor plug and introducing Vanna, who would come on and read the clue for the game, such as "Today's radio Wheel of Fortune category is (chimes) same name. There are four letters, and the second letter is I. Rogers, Smith, or your own free accord." The theme continued underneath for the local announcer to give the phone number for listeners to call with the answer (5th caller at, etc.) Second cut was a dry reading with Vanna and the clue, no sponsor plug or music. Third cut started with a "correct letter" chime, then the theme and Vanna saying, "That's right...the answer is will. Let's see what you won!" Theme continued for local announcer prize copy read-over. In our case, travel bottles of Nexxus products. Let's see what Jake comes up with. Looks like the ones pictured have the barter spots listed and might have had various prizes. Our version didn't.
