## What is Testimony?

Testimony: Daily Deduction serves one new whodunit every day. Read the suspects' statements, work out who was where, and accuse the culprit.

The rules are simple: every suspect either always tells the truth or always lies — and the culprit always lies. From three lines of logic, every case can be cracked by pure reasoning. No guesswork: each puzzle is machine-verified to have exactly one answer.

• A new case every day — today's case is always free
• Three or four suspects per case
• Mark who was where on the alibi board to catch contradictions
• Step-by-step solution replay after every case
• Plays in 10 languages: English, Japanese, Spanish, Portuguese (BR), German, French, Turkish, Russian, Hindi, Indonesian
• Works offline — no account, no ads

The optional Past Cases subscription unlocks the archive of every past case. Playing today's case never requires a purchase.
