To begin, choose one of the crossword puzzles from the drop-down list; each is rated for difficulty as 'easy', 'medium', or 'hard'. Use your mouse or the arrow keys to move around the puzzle. The dark red square is where any letter you type will be placed.

If you get stuck on a word, try solving words around it; the shared letters may give you a clue. You can also press the "Need a Clue?" button to get some help—but not every puzzle allows clues! You can also check for errors as you solve the puzzle; just press the "Check for Errors" button and any incorrect letters will be highlighted.

Solve each puzzle as many times as you like. Try to better your time!
