About Sudoku Pro

Sudoku Pro is a free Sudoku game. Fill the 9 by 9 grid so each row, each column and each 3 by 3 box contains the digits 1 to 9 exactly once.

Every level has a puzzle with one unique solution. Early levels give many starting numbers, and later levels give fewer, requiring techniques such as pairs and elimination. Pencil notes let you mark candidates in a cell.

Hints are available as power-ups. Fewer mistakes and fewer hints earn more stars.

Tips for Sudoku Pro

• Scan for a digit that can fit in only one cell of a row, column or box.
• Use pencil notes whenever a cell has two or three candidates.
• If you are stuck, move to another box and come back later.
