Costcodle answer for October 4, 2023

Puzzle #15. 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 Coca-Cola de Mexican Glass Bottles, Made with Pure Cane Sugar, 24 x 16.9 oz. The price stored for this puzzle is $26.99. A winning guess is any amount from $25.65 through $28.33, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $20.25 to $33.73.

How I would have opened it

If I had started this day at $16.19, that guess would sit about 40.0 percent under $26.99. 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 $25.65 to $28.33.
