Costcodle answer for May 9, 2025
Puzzle #598. 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 Imuraya Original Castella, 15 x 1.4 oz. The price stored for this puzzle is $11.49. A winning guess is any amount from $10.92 through $12.06, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $8.62 to $14.36.
How I would have opened it
If I had started this day at $6.89, that guess would sit about 40.0 percent under $11.49. 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 $10.92 to $12.06.
