It is not a challenging game

I enjoyed the game but once I solved the puzzle, I pressed every button and finally had to close the game to play again.

Don't Make A Mistake Late On

It is a good game BUT, if you make an error and discover it later in the game, you must run a series of "undo's". It needs a "Clear" button to make it easier for we who are not so good at this. It is like doing one on paper, using a pen.

Good but too big

I agree with Stephen, the game grid is too large for me. These are the changes I'd like to see: 1) Resizeable grid 2) Points or percentage win 3) Recommendation to next level when appropriate 4) "Next game" to find 5) Quit easier to find

Just OK

Easy to make mistake when swapping cell entry mode; Game grid too large. Make it scalable, please . Options, new game, undo, etc could be on the same screen instead of requiring swipe. Good variety of game difficulty but 'easy' games

Good Game

At least for the MS Surface Pros this software has a huge flaw. Once a puzzle is finished, the only way to go to a new puzzle is to close the program completely and then reopen it. Otherwise the completed puzzle just twirls around on the screen 4-ever! I like the game but honestly it is not very user friendly to play more than 1 puzzle.

puzzle spin

I do not like the way it continues to spin you finish a puzzle

Sudoku Classic

Can there be an option of an error showing as a red figure to alert the player and/or can one have the option of turning the error option on or off.

Most relaxing internet Sudoku I have played.

I enjoy not being timed so it is just like the one I play in my puzzle books. Other features: Changing background; Option of Automatic notes; multiple levels; easiest switch between manual notes and number insertion mode, and other goodis.. The only draw back is no dictionary for their instructions.

everything you expect

This is exactly what I expect out of a Sudoku puzzle game. The previous reviewer is wrong. There are two ways to remove a number you put in that's wrong. You can press the Delete key or you can use Undo. The puzzles are weighed one-off based on my experience. For instance, medium really is hard. That's not a problem just something to keep in mind if your time is limited.
