Daily Chain Sudoku

Play Chain Killer Sudoku levels. Fill the grid with the numbers from 1 up to the size of the grid. Each number appears only once in every row, column and chain.

1. 1

   Each box, row and column must contain each number once - no repeats.

2. 2

   Look at the empty cells and cross out numbers that already appear in that row, column or box.

3. 3

   The number left over is the only one that can go there.

4. 4

   Type the number in, or tap the cell and choose it.

5. 5

   Stop when every empty cell is filled - then check for mistakes.
