    1) dual input pads - one pad for notes and another for actual input. It saves a lot of time in toggling between the two for a lot of games
    2) accurate reverse moves - people will make mistake and can have the comfort that they can restore the original position
    3) magic note option - I have it on all the time. It removes the tedious steps in doing everything manual
    4) the X button is great because it removes all your personal notes when I make mistake in creating wrong note
    5) area calculator to list all possible alternatives

    Area for improvements:
    1) colorize the areas - it is very hard to see the border lines
    2) calculator allowing user to input just sum and number of cells. This will compliment the area calculator.

    Thank you very much for your feedback and suggestions! We took a note of these ideas, and will consider when we have our next app review.
  • Brain-bending fun

    These puzzles exist in other apps and books, but the convenience of the app doing the sums for you and being able to cross them off makes them actually doable
  • Love it!

    I love this app. I find it a real stress reliever.
    Thanks for fixing the issue with the options not greying out.
    And the new feature with the options and being able cross them out is brilliant. Thank you.

    The issue you mention (greying-out numbers that are already set) was caused by a bug in Apple's iOS 14. We have a fix which will be released in the next update.
  • Go to game

    Need more levels, about to run out of games. 😁
    Recently changed the button that would erase all pencil to a button that adds all possible marks. It would be nice to have both.

    Pretty good program

    Add more of auto load pencil marks. Allow to select cells and then fill in or take out pencil marks of multiple cells at the same time.

    If you make a change the auto changer doesn’t work right. For example, if you put an 8 in a cell, all the pencil marked cells affected by the 8 are changed. However, if you change that 8 to a 7, those pencil marks aren’t changed back to 8 unless you use the undo button.

    Thank you or your comments, but we're not sure what you mean about the "auto changer not working right". When the Autofill Pencilmarks button is ON and you change that 8 to a 7, those pencilmarks DO change back to 8. In case you still think there is a problem please send us an email to support@conceptispuzzles.com with more explanations so we can improve our app.
  • Excellent

    Addictive.
  • Good challenge levels

    Appreciate the functionality.
  • Some sudoku

    A good level of challenge in the ‘hard’ section. Puzzles have sufficient complexity and variety of methods required to solve.
    Check option is helpful but not essential.
  • Very good game!

    I love those challenges! 😊
  • Good.

    Very good game. Some “cheating” opportunities in features but purists can jgbore them (check feature). No. 19 in medium section is flawed, a cage marked 20 has only 19 total.
    N.B. That anomaly is now fixed for that grid. I am trudging on with the other puzzles, limiting use of “cheating” opportunities (overuse of check facility).

    Thank you for your feedback. However, please note there is no error in the cage marked 20. If you find it only has 19 then this is because you made an error somewhere in the solution. If you send us a screenshot then we can show you where you made the mistake.
