There are certainly a lot of puzzle and line-drawingÂ games in the App Store these days. But how many puzzle line drawing games are there? Â Piczle Lines is a unique combination of the two, using line drawing to complete picture puzzles. In fact the nearly unpronounceable name of the app is derived from PICture + puzZLE = piczle. I decided on “pixel” since you are drawing pictures in a pixellated way as you will see below.
