Futoshiki Daily Logic

Futoshiki looks like a small sudoku until you notice the signs. Each row and column holds every number once, and the greater than and less than marks between cells have to be true as well.

You get 300 boards in three packs: Easy 4x4, Medium 5x5 and Hard 6x6. Every one has exactly one answer. I checked them all with a solver that works the way a person does, so you never need to guess. Every Hard board asks you to find a pair of cells sharing the same two numbers at least once.

The daily puzzle is the same for everyone. It's 5x5 from Monday to Thursday and 6x6 from Friday to Sunday.

Hints mark the cells that matter and explain the step in one sentence, like "The signs step down from here through 1 cell to the 2, so this cell is at least 4." They're unlimited and never tied to an ad. Mistakes cost nothing, and you can switch the mistake check off.

It works offline and you don't need an account.
