What is Lie of Sight?
A cozy daily mystery logic puzzle. The family each tell you what they saw in a room, and exactly one of them is lying. Check every story against what each person could really see and catch the liar. One new case a day, free in the browser, no account needed. I'm the developer.
How to play Lie of Sight
- Read the statement cards. Each shows what a family member claims to have noticed (or not noticed). An eye means “I saw it,” a crossed-out eye means “I did not see it,” and a nose marks Rex’s smell claims.
- Drag family members onto squares in the room. Cards turn green when a statement is true from the current positions and red when it is false.
- Adjust placements so that every statement except one can be true simultaneously. The remaining red statement belongs to the liar.
- Tap Accuse on that person’s card, then confirm. Most cases allow three guesses; a wrong guess costs points and lets you continue.
- After solving, review the result board that shows a valid arrangement and the reason the liar’s statement could never hold.
How each family member notices things
Each person follows one fixed rule. Walls and tall furniture block visual lines of sight; people never block anyone. Low furniture blocks only the Kid.
- Dad sees the entire row and column he occupies. Tall objects and walls stop the line beyond them, but he can see the blocking object itself.
- The Kid also sees his full row and column, yet low items (tables, sofas, vases) block him. He can stand under some low furniture while remaining visible to others.
- Grandma sees two squares in every direction, including diagonals. Tall objects and walls block her; she can look past a corner only if she could step around it.
- Rex the dog does not see. He smells the eight surrounding squares, including through walls and furniture.
- Fibs the cat (featured in the Cat Files) looks only along her four diagonals. Her own row and column are blind; tall objects and walls block her, but low objects do not.
Tips for finding the liar
Begin with the tightest constraints. Grandma’s two-square limit and Rex’s adjacent smell range quickly rule out many placements. Statements of “I did not see it” are equally useful: they force a wall, tall object, or distance to stand between the speaker and the object.
Place people freely; movement has no cost. When cards remain gray, use a Check (available on later cases) to reveal which statements are actually true. A lightbulb hint appears after thirty seconds if needed; it highlights one square and suggests who to try there.
A new case appears daily at midnight local time and is identical for all players. Solving it on the day builds a streak. Twenty-eight additional free cases (practice, Case Files, and Tricky Cases) are available at any time. No account or download is required to play; an optional free account simply keeps the streak across devices.
