It is rare to see some games like this.
Yup, it is a rare gem. Nice twists on the regular game, while maintaining simplicity. I love that there is a pencil-in feature. The only improvement I'd like to see is some sort of indicator when all of a digit have been filled in.
Can't wait until they do kakuro. Kakuro is a much more challenging puzzle than sudoku.

Really fun! I can only do the classic and diagonal ones though. As Zazazu said, the only way it could be improved is if it showed you which numbers were completed. That way, you wouldn't spend time reviewing numbers you've already finished.
The pencil-in feature is pointless: it only lets you pencil in one number per square. Also, I haven't found a way to turn off the error checking - I don't want a puzzle to tell me when I put in the wrong number (not least because 99% of the time, it's the stupid interface being recalcitrant, not me making a mistake). All in all, I'd give this one a miss.
Reka, you can put more than number in the penciling in, you have to click in the upper left corner of the square. Once you have that filled in, you can add more by moving the most more to the right each time.
