A bit cleaner layout than the alternatives but WAY too big. Is this for the visually impaired?

Also the trick with having to select a number which floats on the tip of a silly pencil cursor, then needs to be clicked into place was too round about for me. Especially as the default for the pencil cursor is an eraser.

Let's get this in order, 1st you put something in, then you can undo it, not the other way around.

Otherwise it does the job.

But can we just have a clean type-it-in Sudoku? The game is the thing!
