I'd say of all the non-car/cash games, Grocery Game's win percentage remains quite abysmal, mostly due to far too many contestants going over on their first pick. Raising the win range to $20-$22 in 2016 was helpful in terms of usually resulting in a win for those who knew proper strategy, but I'd say raise it to $40-$42 since grocery items used are quite expensive nowadays. $7 in 1972 is around $45 today. Bullseye's target range is also due for a raise as its been 30 years now since the current values were introduced ($4, $8, $12, $16, $20, $24 would be my target values).
I'd keep the redesigned 3 Strikes bag, but I'd just use the classic chips due to the issues presented.
Temptation should lower the ratio between car price and gifts offered, since far too many bailouts are being used.
As far as Pick-a-Number, it's a necessary evil as a quickie, but like Double Prices recently, needs a good touch-up with set.
