About the game
Inside every box, small signs between the cells tell which of two neighbours is bigger. Hardly any numbers are given: the signs alone lead you to the solution.
Rules
Fill the grid so that every row, every column and every 3×3 box holds each number from 1 to 9 exactly once.
The sign between two neighbouring cells points at the smaller number, like 3 < 7.
Every puzzle has exactly one solution, so it can always be found by reasoning, without guessing. A number that breaks a rule turns red.
How to play
- Tap a cell, then a number below the board (or type it).
