Puzzles are ok but too many glitches – Cool Sudoku & Cool Puzzles Review

I tried to solve a puzzle but it was hard to switch from pen to pencil and sometimes it didn't change. It would also refuse to clear a square when I decided I wanted to redo everything in it. I love sudoku but this just didn't cut it for me. I gave it 2 stars because it looks nicer than some of the others out there and the puzzles are adequately difficult.
