Standard 9x9 Sudoku, but with a twist! The initial entries are hidden (but are revealed when the puzzle is solved). "Pencil Notes" are provided and accurately reflect the cell possibilities. There is still no guessing required (and is still discouraged! LOL) - 34 puzzles. Four levels of difficulty. Rules of Sudoku not provided here. Select a puzzle (on-screen arrows beside Level indicator). Click on a cell to select it. Click the on-screen (or off-screen) numbers to place one in the selected cell. Duplicates will be marked in Red. Click on Zero to clear the cell. On-screen "R" to reset/re-load puzzle. "Auto-notes" is initially enabled by default. Click the "Pencil Notes" icon (twice) in the bottom-right area of the screen to enable Manual entry of "pencil notes". Once enabled clicking on a number will enter/clear a note. Clicking on the "pencil note" icon again will enable/disable "auto-notes" mode. In that mode all notes will be created/erased based in placed numbers only. Disabling auto "pencil notes" mode will not erase existing notes. For using advanced solving techniques on difficult puzzles, you will most likely want auto-notes disabled. To continue cell entry mode, click on the "number" icon (looks like an "8"). Feedback welcome and encouraged!
100% pen. All puzzles created by Michael Mepham. Reported puzzle difficulty levels are as per the authors own ratings. (except: The rating "Fiendish" sounds a little dramatic to me, so I use "Hardest". LOL)
