Costcodle answer for January 21, 2024
Puzzle #124. 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 Ito En Black Milk Tea, 12 X 11.8 oz. The price stored for this puzzle is $13.49. A winning guess is any amount from $12.82 through $14.16, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $10.12 to $16.86.
How I would have opened it
If I had started this day at $8.09, that guess would sit about 40.0 percent under $13.49. 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 $12.82 to $14.16.
