Sudoku is a game played on a square grid. Sudoku Quest has levels with grids ranging from 4x4 to 10x10.

To explain the rules of Sudoku, let us take a 6x6 grid as an example.

The Sudoku Grid is divided into 6 Rows, 6 Columns and 6 Blocks.

Each Row, Column and Block must contain numbers 1 to 6 without repetition.
