About Costcodle
Costcodle arrived on October 15, 2026, bringing Zachary Kermitz's take on a daily challenge built around guessing product prices. Built with HTML5 and Unity WebGL, Costcodle works directly in browsers across computers, phones, and tablets.
Instead of solving a word, each daily round asks you to study a Costco item and estimate how much it costs. You see a Costco product and get six attempts to work out its price. Your guess does not need to match the exact number. Landing within 5% is enough to solve the puzzle.
That simple rule makes each round surprisingly tense. A familiar snack may seem easy until you notice it comes in a huge multipack.
Controls Guide
- PC: Click the price box, type your estimate with the keyboard, then submit it.
- Mobile: Tap the input field, enter a number with the on-screen keyboard, and tap Submit.
There are no movement keys or complex controls. Most of your time goes into judging the product rather than learning buttons.
Gameplay and Interface Overview
Each daily puzzle shows a real Costco item with information that can help you estimate its value. After a guess, the interface tells you whether the actual price sits above or below your number.
The colors add another clue:
Green: You are within 5% and solve the puzzle.
Yellow: You are within 25%, so your estimate is getting close.
Red: Your guess is still more than 25% away.
In my test approach, the higher-or-lower arrow was more useful than simply chasing colors. Once two guesses create a reasonable upper and lower limit, the puzzle becomes a small number game rather than a blind shopping quiz.
Costcodle Tips and Tricks
- Check quantity: Costco sells many products in bulk, so look at pack count and size before typing a familiar supermarket price.
- Build a range: Avoid jumping between random numbers. Use each higher-or-lower clue to shrink the possible range.
- Watch for yellow: Yellow feedback shows your price estimate is getting close, so make a smaller adjustment on your next guess. Make a smaller adjustment on the next try.
- Save guesses: If $20 is too low and $30 is too high, try the space between them, rather than going back to a range you already eliminated.
Costcodle is best as a quick daily logic puzzle. Product knowledge helps, but careful estimation and smart use of the clues matter just as much.
