Costcodle answer for September 28, 2023
Puzzle #9. I read this row from the official games list. The date is the UTC calendar day sampled at noon; your live game may show another number in your time zone.
The shelf price
The item is Diet Coke 24 x 12 oz. The price stored for this puzzle is $10.49. A winning guess is any amount from $9.97 through $11.01, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $7.87 to $13.11.
How I would have opened it
If I had started this day at $6.29, that guess would sit about 40.0 percent under $10.49. Anything beyond 25 percent away is a red tile. I would then jump toward the middle of the remaining range instead of nudging by a dime. Once a guess lands inside the yellow band I only test the center of $9.97 to $11.01.
