Sudoku creates the crossword-like logic puzzles that exercise your brain.
This Sudoku game generates nearly 1000 levels. The objective of puzzles is to fill a 9x9 grid so that each column, each row, and each of the nine 3x3 boxes contain the digits from 1 to 9 only one time each.
Solving a sudoku puzzle can be rather tricky, but the rules of the game are quite simple.
Solving a sudoku puzzle does not require knowledge of mathematics; simple logic suffices.
