Free daily logic puzzles
Sixteen logic puzzles with one new board apiece every day. Pencil-and-paper classics (a nonogram, a slitherlink loop, shikaku rectangles, a sliding block puzzle) alongside deduction puzzles built around suspects, liars, hidden rules and results tables. Every board has exactly one solution and can be reached without a guess.
The grid puzzles are the ones you may know from puzzle books. Etch is a nonogram: fill the squares the row and column counts force and a picture appears. Hedge is slitherlink: draw one closed loop so every number has that many sides on it. Plot is shikaku: cut the board into rectangles so each number owns exactly its own. Parker is the sliding block puzzle where you get the red one out.
The deduction puzzles give you statements instead of a grid. Alibi narrows four suspects to one across three boards. Sworn has five sworn statements with an exact number of lies. Hearsay works out what two people can and cannot know. Docket and Suffice are the reasoning sections of two well-known standardized tests, one setup and five questions, or two statements and a verdict on whether they settle it.
Etch or Plot if you like a grid. Alibi if you like a whodunit. Axiom if you want something nobody else has: one hidden rule and a handful of tests to tell five candidate rules apart.

No. Every board is proved to fall to logic alone by a solver that is independent of the one that generated it.
All sixteen, every day, no account required.
