Costcodle is a daily price guessing game about Costco food products. You enter a dollar price for the pictured item and use higher or lower feedback to reach the target range within six guesses. In our desktop test, two overestimates led to a much lower third guess, which changed the feedback from red to yellow and gave us a useful foothold.
Read the pack before pricing it
The product card combines a photograph with a name and pack size. Our test item was a twelve bottle seltzer pack, with each bottle labeled as one liter. That quantity matters: guessing the cost of one bottle would answer a different question from pricing the displayed pack.
Type a number into the dollar field and press Submit. The page formats whole dollar entries with two decimal places, so entering 20 produced $20.00 in the guess history. Previous guesses remain visible, letting you compare your next estimate with the numbers you have already ruled out.
The help panel says you have six tries and win when your guess is within 5% of the target price. An exact cents match is therefore unnecessary. The interface uses a dollar sign; our test did not establish a regional currency selector, tax treatment, warehouse location, or the date behind the stored price. Treat it as the puzzle's target rather than a current shopping quote.
What the arrows and colors tell you
Read direction and distance separately. An upward arrow tells you to raise your guess; a downward arrow tells you to lower it. The official help examples distinguish a red guess more than 25% away from the target from a yellow guess within 25%. A check mark identifies a winning guess inside the 5% margin.
Our opening $20 guess received a red downward arrow. Dropping to $10 still returned red and down, so our first adjustment had not gone far enough. We then tried $5 and received a yellow upward arrow. That third attempt did two jobs: it changed the direction we needed to move and showed that we were closer.
A further increase stayed yellow and pointed upward again. One smaller adjustment then won on attempt five. We are withholding that final guess and the revealed price to keep this review spoiler free. The important lesson from the sequence is that yellow means close, not solved; the direction arrow still deserves attention.
Adjust the size of your next move
Once you have one low guess and one high guess, keep the next estimate between them. Before that, a red arrow can justify a larger change. After our first two guesses overshot, repeating small downward nudges would have spent attempts without responding to the distance clue.
Yellow feedback made smaller changes more useful in this particular round. It did not give an exact amount to add, and this one win does not establish an optimal opening price for every product. Familiarity with the pictured groceries may help you choose an initial estimate, while the subsequent feedback gives you something firmer to work with.
The daily format and who made it
The original page promises a new puzzle every day. We found help and statistics controls, but no archive or practice selector on the tested interface. Separately operated sites using the Costcodle name should not be assumed to offer the original game's modes.
The website credits @Kerm, and the developer's project identifies Zachary Kermitz. The Costcodle project profile states that it is unaffiliated with Costco. This is a creator's price puzzle, with no basis here for describing it as a Costco authorized promotion.
We completed one live daily round on October 24, 2026, in a desktop browser inside a cross origin iframe. Afterward, the statistics panel showed one played game and a single entry in the five guess distribution row. A Share button appeared on the result screen, but we did not test sharing. Mobile play, saved progress across sessions, and the daily rollover time remain unverified.
