It's good, controls are easy to use and the layout is easy on the eye. My only complaint is the way the hint system works - a time punishment is good, but i think you should only have a few hints and instead of appearing from top to bottom should be in random positions.
It seems to work! The sound quickly gets annoying but at least it can be turned off, all in all very good
Uh, fine I guess.
I tried one, just to see how it was made.
The game itself is nothing new, so instead of originality I mean to review playability, enjoyability, correctness and graphics.
The insertion method works quite fine, even though it could be improved with a more "transparent" kind which lets you see what's below. Other than that there isn't much to say about playability, as easy as the game is.
About enjoyability... The game entertains you just as much as a traditional Sudoku can, no more no less. So there is nothing to be noted in this field, nor anything to despise.
Correctness. Well, the fact that is that the first one I tried actually had two possible solutions and thereas is probable there will be more like that.
Graphics: again nothing to be so excited about. Nothing too flashy and neither a more classy looking work.
In conclusion... Yeah, "Nothing Too New Or Interesting", quoting the 0-5 evaluation box.
I'm not reviewing sound as I don't have an opinion about it and I don't believe it is such an important matter in this kind of game.
