What's New in Version 9.0.2

- a new setting for "Default digit entry mode" ("Digit fist" vs. "Cell first")
- undo / redo now works for pencil marks as well as numbers.
- a new "Auto pencil" setting for erasing / adding pensil marks automatically as cells are solved / cleared.
- a new setting for highlighting cells that contain the selected digit.
- a new menu option: "Auto-fill" will fill out the pencil marks in all the empty cells (using this option counts as using helper, since it may, inadvertently, reveal parts of the solution).
- now there is a way to reset high scores / history (see Settings->Reset all scores).

Customer Reviews


I came across this version when the sudoku I had been playing for years suddenly began putting intensely irritating, noisy pop-ups in every time you successfully completed a puzzle. It took all of ten minutes to become a fan!
The easy levels pass the time and the hard and extreme levels make you earn your corn!


Interface is very intuitive, enabling quick and easy number entry. Coloured cell prompts help highlight same numbers, error highlights in Easy mode helps guide and coach in preparation for higher levels. As a novice soon became quite expert but still find the more difficult levels a challenge. Great for waking your brain up on the morning commute.


My times to do the extreme vary between 20 and 50 minutes. When I upload I typically get a message 'better than 5% of scores today. Thinking I must be thick I cheated by transcribing the starting numbers to a sheet of paper and doing it manually (as it were). I then loaded the game and completed it in 4 minutes - which I expected to be a record - but no, I was still only in the top 20% or so. Either there are a lot of very clever players or a lot of cheats.
