Costcodle answer for December 31, 2025

Puzzle #834. 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.

Diamond Crystal Iodized Salt, 4 lbs, the Costcodle item for 2025-12-31

The shelf price

The item is Diamond Crystal Iodized Salt, 4 lbs. The price stored for this puzzle is $0.99. A winning guess is any amount from $0.95 through $1.03, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $0.75 to $1.23.

How I would have opened it

If I had started this day at $0.59, that guess would sit about 40.0 percent under $0.99. 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 $0.95 to $1.03.
