There's also a menu option that lets you check all the squares to see if they're filled in properly. I never chose that so I don't know what it does or if there's any penalty attached to it.

IIRC you can only use it once per puzzle and I feel like there is some indication on the file that it was used but I don't recall at the moment what it would be.

On a side note I went back to one of the e games I haven't yet finished last night and as much as I still enjoy the S series, there's something immensely satisfying about just swiping the stylus across the touchscreen to mark a whole bunch of squares at once.
