Costcodle answer for December 18, 2023
Puzzle #90. 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 Cello Shaved Parmigiano Reggiano, 16 oz. The price stored for this puzzle is $15.49. A winning guess is any amount from $14.72 through $16.26, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $11.62 to $19.36.
How I would have opened it
If I had started this day at $9.29, that guess would sit about 40.0 percent under $15.49. 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 $14.72 to $16.26.
