The Daily Signal
The Daily Signal presents three short English logic puzzles per UTC day where you read statements, identify the single location that matches each rule, and compare how many you solve on your first try.
Play The Daily SignalA fresh puzzle is waiting for you.

The Daily Signal is a daily set of three brief logic puzzles that share a single hidden signal concept across the set. Each puzzle statement describes constraints and you must locate the one position that satisfies the rule; every case has one unique answer. There is no timer or account required to play, and a Japanese interface is available.
Cases rotate at 00:00 UTC and the same-day puzzles can be shared with a friend via a date link so both players see the identical set. Your first-try score is the focus: the site highlights how many puzzles you solved on your first attempt but does not permanently save individual scores. An archive and longer mystery called The Last Signal are linked from the site.
How to play The Daily Signal
- Open today’s case and read the first puzzle statement carefully.
- Examine the candidate locations or items presented with the statement.
- Use deduction to eliminate options until one location satisfies every condition in the rule.
- Submit your chosen location for the puzzle to see whether it matches the hidden signal.
- Repeat the process for the second and third puzzles in the set.
- Use the date link or the share option to send today’s same puzzles to a friend for a direct comparison.
Tips for The Daily Signal
- Start by marking any option that directly violates a stated condition to narrow choices quickly.
- Look for absolute terms such as always, only, or none because they let you eliminate multiple candidates at once.
- Compare constraints across the three puzzles; shared elements can give context that speeds deduction.
- If you get stuck, work backward by assuming a candidate is correct and check which statements would fail to disqualify it.
- Play the optional bonus cases only after finishing the main three to avoid confusing the first-try score metric.
