Costcodle answer for January 9, 2025
Puzzle #478. 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 Lactaid 0% Fat Lactose-Free Milk. The price stored for this puzzle is $4.99. A winning guess is any amount from $4.75 through $5.23, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $3.75 to $6.23.
How I would have opened it
If I had started this day at $2.99, that guess would sit about 40.0 percent under $4.99. 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 $4.75 to $5.23.
