I also find it interesting that Bob still emphasized that it wasn't just the regular Dice Game being played but the Deluxe Dice Game, even though the final four-digit playing had already occured five weeks prior. A 2 as the second digit was a nasty number in those early days, as far too many contestants went with the odds while refusing the reality that $11K cars were commonly used if it wasn't a $12K car.
Also, the ninth audience curtain by now has been added to completely cover the control room and all curtains now have their sets of two curves on them, and the familiar green-orange-blue-red-green-orange-blue-red-green pattern that would last with a few exceptions/changes through early Season 30, and still remains the longest-lived audience curtains.
Finally, the Showcase Showdown win graphic is now a normal Helevetica after being Italic more or less throughout 1987 (and surrounded by a border from sometime in Season 12 until mid-Season 15), this would prevail until the star graphic was introduced in Season 21.
This was probably one of those episodes I may have tuned on as a toddler yet only remember the colors, sounds, product brands, and shapes, since I clearly remember the transition from the Pricedown Wheel to the "Super-Ball Wheel" and seeing it alternate during the 1988 summer reruns.
