The rules to fill a grid are simple:
Each block must contain all the digits from 1 to the number of cells in a block. So for a block of 4 cells, they must contain 1, 2, 3 and 4. For a block of 2 cells it must contain 1 and 2…
Two numbers in neighboring cells must be different (including in diagonal).
That’s it! Use these two simple rules and your logic to solve the puzzles.
The game contains hundreds of puzzles. Obvious mistakes are detected and highlighted to help you. If you get stuck on a puzzle you can also use hints. For hard puzzles, you can also use notes to solve the most challenging parts.
