Costcodle answer for September 29, 2023
Puzzle #10. 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 Raw Tail-On Shrimp 21-25 ct, 2 lbs. The price stored for this puzzle is $16.49. A winning guess is any amount from $15.67 through $17.31, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $12.37 to $20.61.
How I would have opened it
If I had started this day at $9.89, that guess would sit about 40.0 percent under $16.49. 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 $15.67 to $17.31.
