SUDOKU TIME is a classic logical puzzle with combinatorics of numbers. The goal of the puzzle is to fill in the empty cells with numbers from 1 to 9 so that in each row, in each column, and in each small square (region) 3 × 3, each digit occurs only once. Each puzzle has only one solution!

The blue cells are empty, green means you're on the right way to the solution, red color signals about an error, grey cells are initial cells and they cannot be replaced. Hints will let you know whether you are acting correctly or not.
