Submit a Solution

Here you may submit solutions to any and all open puzzles. All the puzzles in a given month are open. At midnight on the last day of the month, the puzzles will be closed and the answers revealed. Please submit one at a time, and keep your username consistent. You may send one solution per puzzle, so please be sure before you press the submit button. Only your username will appear on the leaderboard. The message field is an optional space for commentary on the puzzles and your experience with them; sometimes sent messages are cited in the monthly round-up as part of the community dialogue, so please be aware of that if you choose to send a note. To receive an email showing which puzzles you’ve submitted solutions to, and which you’ve answered correctly, submit a request here.
