Sudoku 100

A full grid waits on the first screen. In Sudoku 100, the full set covers 100 separate number puzzles arranged across five difficulty groups with 20 boards in each. Progress moves in order, beginning with the easiest set. Later boards unlock one after another. Russian text appears in the game menus.

How to play?

Fill the empty cells with digits on a 9x9 square divided into 81 spaces. The board also contains nine smaller 3x3 blocks. Place numbers so a row never repeats a digit. The same rule applies to each column and to every small block. Given digits are fixed in place and shape the solution path. A board with more preset numbers is easier to finish. Fewer presets leave more empty spaces to solve.
