Sudoku for iPhone

Overview of the app

Sudoku — from Block Puzzle Games — is a free iPhone title that delivers the classic number-based logic puzzle. The goal is to fill the grid so each digit from 1 to 9 appears once per row, once per column, and once in each 3×3 box. It’s an excellent choice if you enjoy mental workouts and sharpening number skills.
