Goal: guess the hidden word before you run out of tries. After each guess, every letter is colored to show how close it was — see the legend above the board for what each color means.
Typing: use your physical keyboard or tap the on-screen keys. Enter submits a guess, Backspace removes the last letter.
Length slider: sets how many letters the word has (3–12). The number beside it shows how many possible answers exist at that length.
Attempts slider: sets how many guesses you get. It suggests a sensible default for the chosen length, but you can set it to anything you like.
New Puzzle starts a fresh word using your current Length and Attempts settings. Reveal Word gives up on the current word and shows it, along with its definition.
If a length shows "no words available," that word length doesn't have enough entries in the dictionary — try a different length.
