Guess the daily science/geology term in 6 tries. After each guess, the tiles change color to show how close you were:
- Green — right letter, right spot.
- Yellow — right letter, wrong spot.
- Gray — that letter isn't in the word at all.
- Some answers are two words or hyphenated — the space/hyphen just shows as a blank tile automatically, you don't need to type it in the right spot.
- Hint is optional and hidden on purpose — click "Show hint" anytime if you're stuck. It won't stop you from winning, but it's noted in your stats so a clean solve and a hinted one are different.
- The full definition (and the exact term) only shows once the puzzle is over — win or lose.
- Check Stats for your own streak/history, and Leaderboard to see how you stack up against everyone else.
- Once you finish, hit Share to copy a spoiler-free result (no letters, just colored squares) to brag about.
