Cobble

Cobble is a short web word puzzle in which the player must find two words that together use up all the blue letters shown. You submit a solution by typing the two words separated by a space and pressing space after the second word. The interface encourages minimizing any extra letters used and supports repeated submissions.

1. Examine the blue letters you must use.
2. Type two words that together use all the blue letters, with a single space between them.
3. Press space after the second word to submit that solution.
4. You may submit as many solutions as you like; aim to use as few extra letters as possible.
5. Log in if you want to save scores or reveal official solutions.

Cobble is a concise letter-combination puzzle that challenges you to pair two words to exactly (or efficiently) use a given set of blue letters. It rewards concise solutions and lets you iteratively submit attempts, with scores and a leaderboard visible through the site.

Submitting a solution is performed by pressing space after the second word; the site records scores and offers a leaderboard (Loading leaderboard...). Scores are saved to your account only when you log in ("Log in to save your scores"). Official solutions are hidden until you log in ("You need to be logged in to reveal").
