Again a Sudoku! expect some hard levels here :) How to use: Mouse-ponter moves activ field. Insert numbers with your numkeys on your keyboard (1,2,3,4...0 to clear) into the active field. Click the Check button to test if the sudoku is solved right. Choose a new level with the slider, click "load" to continue. Actually there are 30 levels. New: help mode!: (turbo modus required) Click "use help" to fill empty fields with help numbers. Click on a help number to alter its state. If u found a new number, press space key to delete impossible numbers in block, row and colum. That will do some work for you and boost your solvation (i.e.level 7 under 4:00)
Thanks to @Kinderlabor for that idea: http://scratch.mit.edu/projects/2542324/ u may call this a beta version....so.. todo: -a cloud variable to store highscores with playername per level -maybe a helper option that solves some steps (done 28.05.14) -a solution to mark possible numbers per field (done 28.05.14)
