United StatesAmazing
I just love the line puzzles! And, anyway here’s a funny secret to get 3 stars on any level: Make sure that when you are making your solution to not let go.
United StatesTo many ads
I love this game but there are way to many ads which make me don’t want to play it as much.
United StatesInteresting but most of the time is just watching ads
It’s an interesting game but the puzzles take about 5 seconds and then you have to spend better part of a minute watching an ad. In between every. Single. Puzzle. So by downloading this, what you agree to is to just basically watch ads full time with short, intermittent little diversions in between. If this doesn’t sound like your idea of fun, don’t bother downloading this.
United StatesUsed to be fun
This used to be a fun game, hadn’t played in a few years but came back to it and now there is an add every time you finish a level.
