make it easier for first time Sudoku players we have added
these quick playing tips:
1. The board starts with several numbers on it. Their cells
are marked and you can't erase them. Each time you start
a new game, different set of numbers would appear.
The puzzle game object is to fill out the empty board cells
with numbers from 1-9 according the game
For each empty cell, you would have to figure out what numbers
can be inserted, according the game
rules. In the beginning you would have several
options for each cell.
4. We have provided you a small place over the upper side
of each board cell, to type down the different numbers that
may fit that cell.
As you fill out the different options for each cell, you would
see that several cells have only one number option that fit
that cell. In that case you have found the right number for
that particular cell, and you can type it inside the cell.
After you found the right number and typed it, you should
now update the different options, for the other cells over
the puzzle, according the new information.
You should repeat this process through out the whole game.
Eventually there will be no empty cells left, and you succeed
to solve the Sudoku puzzle.
To insure you have no mistakes while solving the puzzle, we
have provided you the "check" button. Pressing it
would tell you if there are any mistakes with the numbers
you chose. This button should be pressed ,in the end after
you have finished solving the game. If you have done everything
right, an appropriate message would appear.
We have added serial number to all of the puzzles. You can
return to any puzzle now by typing its serial number and press
"new game" button. This feature also allows you
to compete against your friends by typing the same puzzle
