The new version of "Computer Aided Sudoku Excel" can be downloaded (free) at http://perso.wanadoo.fr/sudoku.laviron/

with :
- a random GENERATOR of Sudoku puzzles, symmetric or not, four levels of difficulty, to print or play. You can also enter your own Sudoku manuallly
- a board to PLAY with possible management of the candidates (by you or by the computer)
- a powerfull and gradual HELPER
- a fast SOLVER for every Sudoku. Just clic "Solution", but use this action only in case of emergency.
- an HISTORIC table in which are recorded and showed all the plays. It allows to replay partially the game.
- SURPRISES which "appear" when you solve a random Sudoku with no help and no error. Indicator to know if you are approaching the surprise.
- CLINIC where you can analyse your Sudoku without knowing the solution : can it be solved only with basics methods ? How many guesses ? Is it irreducible ? How many solutions ?
In the clinic, you can adjust the level difficulty of the original Sudoku (minus command used once or several times can be very useful for children to make the Sudoku easier)


About the software (1.6 Mo) :
- it is written with Excel VBA macros.
- it uses a large Excel sheet with various parts dedicated to the above functions. You move between these parts with buttons wich select the part you want to use.
- the solver uses a recursive subroutine in its heart
- a lot of programmation was used to check all inputs in the various part of the sheet and to allow interactive messages and checking.
- the game can be saved and restarted.
- the previous version "the ancestor" (0.8 Mo) can also be downloaded
(with open macros, but no generator, no recursive programmation)

Enjoy
