Logic puzzles online

Griddle publishes three kinds of grid puzzle, and a new board in each one every day. They are pencil puzzles rather than word games: a grid, a rule, and one answer you can reason your way to without ever guessing.

One answer, and no guessing

Every board is checked before it is published: exactly one solution, and a route to it that needs no guess. Anything that fails either test is never used. How that works →

More than the daily three

Each game has an Unlimited mode at four difficulties and a timed ladder, and every Daily stays in the archive. 7,041 boards so far.

Nothing to sign up for

No account and no download. Streaks and times are kept on your own device, and the puzzles keep working with no connection.

Star Battle Puzzles

Every row gets one sentinel. So does every column, and so does every coloured region. The catch is that no two of them may stand next to each other, and that includes diagonally.

Star Battle Puzzles

What a star battle puzzle is, how the one-per-row-column-and-region rule works, and the deductions that crack it. Play a free board in your browser, new every day.

An endless supply of star battle boards at easy, medium, hard and expert. No account, no daily cap, no repeats. Every board has one guess-free answer.

Binary Puzzles

Fill the grid with suns and moons. Each row and each column ends up with equal numbers of both, and you can never put three of the same symbol in a line. The small "=" and "×" markers between cells tell you where two cells must match, and where they must differ.

Binary Puzzles

How a binary puzzle works: two symbols, never three in a row, every line balanced. The core tactics, what the markers mean, and a free board daily.

Number Path Puzzles

Draw a single line from waypoint 1 to the highest number, picking up the numbered cells in order along the way. It has to fill every square on the board, and it can never cross itself.

Which one should you start with?

Star battle is the one most people find readable first, because the rule is a single sentence and the deductions are about where a star cannot go rather than where it must. Binairo rewards pattern recognition and is the fastest to solve once the three rules click. Number path is the odd one out: you are drawing a single line rather than filling cells, and it is the most satisfying of the three to watch resolve.

All three are free, and none of them needs an account. If you would rather not choose, the hub shows the day’s three side by side.

Griddle, griddlers and nonograms

A note on the name, because it catches people out. Griddle is a daily logic-puzzle site. It is not griddlers, and it does not publish nonograms or picross, which are the picture-forming puzzles solved from number clues along each row and column. Different puzzle, similar-sounding name. If nonograms are what you came for, this is not the site, and it is better to say so here than to waste your time.
