game. Each time you play you'll be presented with a brand new
puzzle to solve, so bookmark or link to this page so that you can come

puzzles.
Since its rise to
popularity in the middle of the first decade of the 21st century, this
ingenious logic puzzle has captivated the minds of people from all
walks of life throughout the whole the world.
Research has been done
which suggests that logic puzzles like Sudoku truly are good for your
brain. The feeling of accomplishment on solving such
a puzzle is pretty great too!
Instructions
on How to Play Sudoku online
The aim of Sudoku is to
fill the 9x9 board with digits between 1 and 9 so that every row across
contains all of the numbers to 9 without any
repetition. In addition, every single vertical column must
also contain the numbers 1 to 9 without duplicates.
And if that doesn't sound tricky enough, each of the smaller 3x3 grids,
denoted by the thicker gridlines, must also contain the numbers 1 to 9
without repeating any number.
To start a new puzzle,
hover over your mouse over the
Game menu,
then over the New submenu
and then select from
Easy, Medium or Hard
to choose the degree of challenge. Easy Sudoku will
give you 40 numbers toward filling the board, Medium Sudoku will
provide you with 33 numbers and Hard Sudoku will
only give you 26 numbers, leaving you with a really fiendish challenge
on your hands.
To enter numbers on the board, click on any of the grid
squares. You'll see that a colored crosshair is created from
the surrounding squares, centered on the one you have clicked.
Use your computer's keyboard to enter a number, or you can
click your mouse to select from any of the digits at the
bottom of the game. If you are trying to use your
computer's keyboard and no numbers are appearing you may have just lost
"focus" of the web page. To regain focus, simply click on a blank part
of the page and things should be fine again.
If you wish
to remove the mouse keyboard, you can toggle it on or off using the Keyboard menu
at the top of the puzzle. Similarly the Sound can be
toggled on or off too.
It's often in the nature of logic problems, especially at hard
difficulty settings, that you may find yourself going up a
blind alley and may therefore need to backtrack your steps a little
bit. Springfrog's Sudoku puzzles make it easy for you to do
this, in fact much easier than having to rub out your work with a
pencil eraser on paper.
If you decide that you've
entered an incorrect number, you can delete it either by pressing you
computer keyboard's delete key or by clicking on the X at the
bottom right of the game. In addition, you can
also backtrack any number of steps in reverse order by hovering over
the Edit
menu, then selecting Undo.
At any stage you can save your puzzle by clicking the Save option
under the Game
menu. As
long as you keep your web browser on this page, you can then use Game --> Restore
to go straight back to that point at any time, even if you've started
another game since you made the save. Alternatively you can
use Edit -->
Restart to return to the very beginning of the puzzle.
If you get stuck, you can select Hint from
under the Edit
menu to have the computer place one digit on the board. There's also a Solve option
which will complete the Sudoku puzzle entirely, but hey, you don't
really want to give in to that do you?.
Assuming that you've not resorted to the Solve option,
but instead have figured out where all the numbers go yourself, once
you have no more blank squares you can check whether you've achieved
the correct solution by hovering over the Game menu and
selecting Check.
The cmnputer will then tell you whether you''ve been
successful in your Sudoku solving.
Good luck and have fun!
