4 stars: Interesting take on \
5 stars: Very clever puzzles that always seem so simple but take more thought than first glance. It feels a bit like a Soduku puzzle mixed with a draw-between-the-lines. Personally I quite like this challenge as a daily puzzle to do and will spend a lot of time over a while completing the challenges as best I can.
