Costcodle answer for April 21, 2025
Puzzle #580. 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 Cuisine Adventures Spanakopita Spinach & Feta Phyllo Triangles, 48 oz. The price stored for this puzzle is $9.99. A winning guess is any amount from $9.50 through $10.48, because the game accepts a guess within 5 percent. The yellow band, within 25 percent but not yet a win, runs from $7.50 to $12.48.
How I would have opened it
If I had started this day at $5.99, that guess would sit about 40.0 percent under $9.99. 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 $9.50 to $10.48.
