Giới thiệu game

Medium sudoku is where the puzzle starts to push back. You get fewer givens than on the easy level, so scanning for obvious numbers will carry you part of the way and then stall. To finish, you will often need pencil marks and a few classic techniques. Play medium sudoku online for free, with notes, hints, undo and error highlighting, and a unique solution every time.
