Need a better check button.

All in all, it's a good sudoku game but it needs at least a better check button, or better still. Automatically check after it's filled in completely and give you a highscore based on time to completion and number of mistakes.

I agree with the rest

The check button is absolutely necessary, and can't be too much work.

In case you don't know how (sorry if you know already, but I have no idea about your programming skills) :

An easy way to do it, is putting the answer in an array and comparing that one with the correct solution. That's only a couple of lines of code.

You can use exactly the same to load different sudokus in the same graphical frame : make the sudoku an array with the puzzle, with every position in the array corresponding to a position in the sudoku. Adding a new sudoku is simply adding one array for the puzzle and one for the solution.

I also found the hard one rather easy, but that's mainly because I'm a SUDOKU addict and I solved literally hundreds of them already.

You should also make the "main menu" link a button. Now you have to click right on the text, or it doesn't work.

All in all a nice try, and therefore passed. With a bit extra effort, you can actually make a fun game where you can easily add more puzzles.

Guess it's OK

Some music would have been fun, nothing more to add on a sudoku puzzle game.

Also next time, hide the actual puzzle when you reveal the answer. Because it's just quite boring like that.

Improvement

It would be better if the answers in the grid were checked when you clicked the answers button so the user wouldn't have to.

good,but

it needs a check button.something that tells you that what you've done is right and that finishes the game and takes you to the next level or main menu.the answer grid covers the playing grid so you can't see your numbrs and the correct numbers simmultaneosly.Also there's only one sudoku per difficulty.dispite all that,i liked it
