Costcodle answer for December 27, 2025
Puzzle #830. 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 Zephyrhills Sparkling Flavored Water 24/.5l 24/16.9oz (12.675qts). The price stored for this puzzle is $8.99. A winning guess is any amount from $8.55 through $9.43, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $6.75 to $11.23.
How I would have opened it
If I had started this day at $5.39, that guess would sit about 40.0 percent under $8.99. 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 $8.55 to $9.43.
