Sudoku of the day
Every day at midnight (Moscow time) a new sudoku appears here — the same one for every player. Difficulty follows the day of the week: easy on Monday, medium on Tuesday and Wednesday, hard on Thursday, Friday and Sunday, and expert on Saturday.
Solve a daily sudoku to keep your mind sharp: ten to twenty minutes a day is a great workout for attention and logic. Progress is saved, so you can start in the morning and finish in the evening.
