Costcodle answer for October 1, 2025
Puzzle #743. 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 Arrowhead 100% Mountain Spring Water, 48 x 8 fl oz. The price stored for this puzzle is $6.49. A winning guess is any amount from $6.17 through $6.81, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $4.87 to $8.11.
How I would have opened it
If I had started this day at $3.89, that guess would sit about 40.0 percent under $6.49. 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 $6.17 to $6.81.
