Colour Sudoku
This is a standard Sudoku that has been divided into coloured cells. Cells of the same colour must also contain all the digits from 1 to 9. As with other Sudoku variants, this additional rule creates a slightly different solving experience.
Instructions
Place a digit from 1-9 in each empty cell so that each row, each column and each 3x3 block contains all the digits from 1-9. In addition, the grid is divided into coloured cells. Cells of the same colour must also contain all the digits from 1-9.
