Intoducing a new piece of sudoku software from John Layton with a few additional features to help you solve puzzles more quickly.
The game is the same - nine rows, nine columns and nine, nine by nine squares - where the numbers 1 to 9 must never be repeated. Start by clicking the 'New Game' button under the 'Game Options' menu and you will be presented with a new, randomly generated puzzle as shown below.
After studying the board you might come to the conclusion that a particular number should go in a particular square and all you have to do is right click on that square for a numbers keyboard to appear - as shown below.
In order to enter a number into that square just left click on a selected digit and it will be entered automatically. If you decide, after all, you don't want to enter a number in that square just go to another square and repeat the process. At any time during the course of a game you can click on the 'Remove Wrong Numbers' button under the 'Tools' menu and all incorrectly placed numbers will be removed. This is a useful feature to remove your mistakenly placed digits as the game progresses.
Other features of this software include:-
1. The ability to save any unfinished game and reload it later when you have more time to play.
2. The ability to save an image bitmap of the puzzle at any stage of the game. Using your favourite graphics editor you can then resize the images for publication in magazines, periodicals and other kinds of booklets as well as for use in schools, clubs and web sites. By resizing you could get several puzzles on one page thereby saving paper. Also you can save the bitmap image of an empty puzzle, print it out using a graphics program and then try to generate your own sudoku puzzle.
3. Under the 'Tools' menu you will also find a button, which once pressed will reveal the whole puzzle. You will need to save this to bitmap if you intend to publish puzzles because this will also be needed to show the resolution of the puzzle. Below an example of the image output from the program.
