Sudoku is a logic number puzzle game, you need to place numbers from 1 to 9 in each grid cell so that each number can only appear once in each row, each column and each mini-grid. In this case, you can choose strict settings, under which you can make a maximum of 3 mistakes. Or do not enable this function and play with any number of errors.
After starting the game, you need to carefully look at the field with numbers and start filling it out. The rules for filling are simple: there should not be the same numbers diagonally, vertically and in each selected 3x3 field.
When you can’t exactly determine the number that should be in a specific cell, use the “Notes” mode. When you turn on this mode, you can put up to 9 numbers in a cell, and then return to it when there is more data for making a decision.
You also have three free hints, move undo and an “erase” button.
