Here is a new version of Sudoku puzzle!
Playing area represents a 9x9 grid divided into 3x3 sub-grids. Thus the playing area consists of 81 squares. At the start of the game, the board will have some of the squares filled in with digits from 1 to 9; they are called hints. The player has to fill empty cells with 1 to 9 digits so that digits do not recur in each row, each column and each of the nine 3x3 boxes.
The difficulty of Sudoku depends not on the amount of initially filled cells, but on the methods you apply for solving it.
Each puzzle has only one solution.
By clicking on the left button of the mouse a digit will be entered in the cell; the right button — possibles will be eliminated or added.
Difficulty level may be set in parameters.
This is the last method of solving the game, also known as trial and error method.
- Select an empty cell and enter one of the possible values. For convenience, mark the cell by clicking «mark the digit» link, then click on the required cell.
- Solve Sudoku using the methods described above.
- In case all possible values have been exhausted, or you have made a mistake, go back to initial arrangement by clicking «special move» button and eliminate the value you have chosen out of the «candidates».
