Check-Out, probably not for awhile unless if there's severe inflation that basically rivaled the disco years in terms of its length. It actually had its range upped in 2001. $2 today is worth (or will be worth in about a year or two with the current inflation) approximately 50 cents when the game debuted in 1982.
Grocery Game had its winning range increased from $20-$21 to $20-$22 in 2016, so although that was pretty recent, the rather low total may imply that they'll start needing to use cheaper products in order for this game to continue. Still, a $2 spread today is eight times its original 25 cent spread, and $2 is still worth more than what a quarter in 1972 was, although that may be crossed over in a few years. Still, if there was a tweak, it would be more on the lines of simply going from $30-$32 or so, since due to the lack of electronics, the base is easily adjustable.
But Bullseye still has the exact same $10-$12 target since 1989, and unlike the other games, it actually makes the game TOO easy by simply turning it into the "pick 2 or 3 of what you think are the most expensive products, and you'll win" game. Perhaps $15-$18, $20-$24, or even $25-$30 is due.
Coming or Going, Freeze Frame, and Side By Side certainly could be adjusted for five digits just like Squeeze Play and Push Over have done on special occasions. CoG could easily be played for a car, with 2 the common digit since so many cars end with a 2, with $21,342 or $24,312 being a sample setup. The same with Side by Side with $12,159 and $15,912 being a sample pairing for that trip to the Maldives, with the movable digits portion having three digits in a narrower font instead of two, and the electronics adjusted to fit the narrower digits. Freeze Frame could have four choices with $1X,X in term next two digit choices, making four reasonable possibilities. $205, $39, $223, $52, $237, $12, $217, and $03 could be a sample setup for a car. It would be a great way to spice up these otherwise unremarkable quickies, and allow for the occasional NCFC.
Range Game probably will keep its $150 Rangefinder longer than Hole In One keeps its $500 bonus though.
