Before you open a file
All questionsThe questions that come up most often about the files and how they are scored.
What is RedThread, exactly?
An archive of investigative fiction you work rather than watch. Each case is a file: a briefing, evidence you can examine with real instruments, suspects with something to hide, and one answer the material actually supports.
You read, test what you are told, pin what connects on a corkboard, and name a culprit. Nobody nudges you toward it.
More about usDoes it cost anything?
No. The archive is free to read and play right now, and everything currently in it stays that way.
If we introduce paid cases later we will say so plainly, well before anyone is asked for money.
How long does a case take?
Most run 20 to 45 minutes. Every case carries an estimate on its card, and the harder Investigation files can run past an hour if you work them properly.
You can leave whenever you like. Your progress, notes and board are waiting when you come back.
Do I need to be good at this?
No. Every case is solvable from the material in front of you — no outside knowledge, no trivia, no guessing at what the author was thinking.
Start with an Easy case marked Record or Thread. If you get stuck, a case can lend you a hunch for a small score cost.
Read the investigator's guideWhat is the difference between Record, Thread and Investigation?
How much guidance the file gives you. Record is a complete account, read as it stands. Thread opens as you earn it — follow the sequence and connect what matters. Investigation gives you only evidence and no narration at all.
Same quality of mystery in each. Pick by how much scaffolding you want.
Browse the archiveCan I play with friends?
Yes. Rooms put up to six detectives on one file at the same time, with a shared board, shared evidence, text and voice chat, and a verdict the room files together.
One person hosts and shares a six-character code. Everyone needs an account.
