Diddleraily

One riddle is set each day. You submit a single free-text answer — the Judge weighs the idea, not the spelling, so a typo or a synonym that captures the concept is counted correct.

Not every sitting is a thing to be named. Some days the bench sets a deduction, an arithmetic problem, a question of odds, or a piece of geometry — the format is printed under each riddle, so you always know what kind of thinking is wanted. On those days the answer is a value or an arrangement and it must be right; where the bench asks whether something can be done, it wants the reason as well as the verdict. Everything needed is in the question: no outside knowledge, no calculator, nothing to look up.

Submissions seal at 16:00 UTC. One hour later, at 17:00 UTC, the whole world learns the answer together — no timezone finds out early, so no timezone gets to cheat. Times are shown in your own zone, with the bench's UTC in parentheses.

You may answer only once. You may stake an Oath on your answer: whisper it, state it, or swear it. Swearing wrong is the most entertaining thing you can do here, and the bench will remember it fondly.

A correct answer lengthens your streak; a wrong one ends it; failing to appear ends it too. The Judge keeps a record of how your mind tends to work, and is not above referencing your past mistakes.

The Judge's ruling is final. Appeals are mocked publicly.
