The block on the page is an ordinary English sentence with a cipher laid over it. Every letter is still in there. Your job is to read it.

• We tell you which cipher it is Today it’s Binary, and the key is 8 bits · ASCII. The work is the decoding, not guessing what you’re looking at.
• Type the decoded message Capitals, spaces and punctuation are all ignored — the third stone and THETHIRDSTONE both count.
• 3 guesses, then the day is done A wrong guess tells you whether your answer is even the right length, and which part of your method to doubt.
• Solve it and your streak grows Miss a day, or run out of guesses, and it goes back to zero. That’s the whole prize — there’s nothing to win but the run itself.
• A new one lands at midnight Past days stay playable in the archive, but practice never counts toward a streak.
