The game is set up like this with 8 digits arranged in a circular pattern on a "disk":
1 9
3 0
6 7
4 2
There is also a light bluish "window" (similar to that found on Push Over but curved instead) that stretches to include 4 of the 8 numbers. The contestant must rotate this "window" so that when read CLOCKWISE, the correct price of the prize is highlighted. For example:
1 9
3 0
6 7
4 2
This would be read as $2,463, not $3,642.
Also, for ease/simplicity, an LCD screen (something the show seems to love) in the center of the titular disk would update itself for every one of the window's moves.
If played for a car, this game could either be reworked to have 10 digits instead of 8 and a 5-digit window OR the display would simply put a 1 in front of the bid. Of course, since it would be an LCD screen, it would always format the bid with a dollar sign and the thousands separator comma.
Alternatively, the digits on the set and the "window" could also be part of a special LCD touchscreen a la Double Cross.
So essentially this game is a mix of Freeze Frame (numbers arranged in circular pattern), Push Over (light blue window), and Double Cross (touchscreen is used to submit answer).
