Each clerk is either innocent or guilty. Innocent clerks write true sentences. Guilty clerks write false ones. Five benches hold four clerks each, and the sentences talk about those seats. The day's bench has one pattern that satisfies every sentence together.
A sentence stays sealed until you have marked every clerk it names. Sentences about a whole bench name nobody, so they are open at the start. Marking a seat unseals the sentences that were waiting on that seat.
Yes. The bench is chosen by the UTC date, so every player shares one puzzle from 00:00 UTC. Practice mode picks a random extra bench and does not change today's puzzle. The archive lists dates that have already opened.
It names one seat that the open sentences already force, and whether that seat is innocent or guilty. It does not fill the mark for you, and it does not show the rest of the bench. Hints you take are counted on the result card.
