Sudoku-7 Mobile is an interesting puzzle game with simple rules. Playing Sudoku-7 you increase your level of logical problem solving ability, develop imagination and patience. Sudoku-7 includes thousands of different puzzles, so the game remains fresh no matter how many times you play.
I rate it 5 stats because it doesn't require "permission" and access to a phone. Also it takes up only 440kb. The most I've seen was 64 mb. Why so much for a simple game!!??
