Art of Logic

Really great app. A lot of fun. Would be more enjoyable if it had a little bigger working square, have to erase a lot of moves and takes extra time that I could be doing another picture. Over All a great Stress Reliever! Thank you keep up the good work.

Added degree of difficulty

Very much enjoy this app. Love puzzles like this and it has added challenges, but can get your own help by seeing joining smaller puzzles.
