Costcodle answer for January 9, 2026

Puzzle #843. 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.

Nong Shim Tonkotsu Ramen Bowl, 6 x 3.5 oz, the Costcodle item for 2026-01-09

The shelf price

The item is Nong Shim Tonkotsu Ramen Bowl, 6 x 3.5 oz. The price stored for this puzzle is $10.99. A winning guess is any amount from $10.45 through $11.53, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $8.25 to $13.73.

How I would have opened it

If I had started this day at $6.59, that guess would sit about 40.0 percent under $10.99. 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 $10.45 to $11.53.
