Test your logic with our free Sudoku puzzles app, which offers four levels of play from Easy to Very Hard.

The Object of Sudoku Puzzles

Sudoku is a popular brain game/number placement game, which consists of a 9 x 9 grid, divided into nine 3 x 3 sections.

The object of the game is to fill in the grid, and subsections (boxes), with numbers from 1 – 9. Each row, column and 3 x 3 subsection must contain the all the numbers from 1 – 9, and there must be no repetitions of these digits in any row, column or subsection.

Sudoku puzzles can be completed via the process of elimination. With our Sudoku App you can play against the clock to see how fast you complete each puzzle!
