Yay! My favorite time-filler! Nicely done, and it works on my Pandigital Novel 7" black. No sound (this thing only works with .wav and one other sound format) but the music option worked. When switching from medium to expert I got 99 mines in the 16x16 size, but after closing the app and starting over the expert level worked again. Using a touch screen with long touch to flag adds a whole new element of challenge. I LIKE IT!!! There goes my time and battery charge.
