Lie of Sight: a free daily find-the-liar puzzle

About Lie of Sight

Lie of Sight (not line of sight) is a free daily find-the-liar logic puzzle. Each case is a room seen from above, and everyone in the Fibberson family says what they saw, or didn’t see, from where they stood. Exactly one of them is lying.

Move the family around the room to test each story. The honest ones can all be true at once; the liar’s never can. When you’re sure, accuse the liar. You’re not finding who did it, just who’s lying about what they saw.

Each of the family notices things by one rule. Walls and tall furniture block a view; people never do.

• Dad sees his whole row and column.
• The Kid does too, but he’s short, so low things like tables and sofas block him.
• Grandma sees two squares in every direction, diagonals too.
• Rex the dog smells the eight squares around him, even through walls.
• Fibs the cat sees only along her four diagonals. She stars in the Cat Files.

A new case opens every day at midnight, your time, the same one for everyone, so you can compare notes afterward. Solve it on its day to grow your streak. Most take two to five minutes. It plays in the browser on a phone or a computer, with nothing to download and no sign-up.

When one a day isn’t enough, 25 more cases are free to play any time: practice, 15 Case Files and 10 Tricky Cases. Stuck? A lightbulb hint shows one square and who to try there. There are no ads, and a free account keeps your streak on every device, but you never need one to play.
