Costcodle answer for July 28, 2025
Puzzle #678. 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 Marianne’s Organic Sunflower Oil, 2 L. The price stored for this puzzle is $7.99. A winning guess is any amount from $7.60 through $8.38, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $6.00 to $9.98.
How I would have opened it
If I had started this day at $4.79, that guess would sit about 40.0 percent under $7.99. 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 $7.60 to $8.38.
