Often its the simple games that are the most addicting. This is one of the few things Ive ever gotten after seeing an ad for it, because I loved One More Line so much, and this does not disappoint. As others have said, though it can get a bit repetitive, and adding more incentives (like the different skins, which I love) wouldnt hurt. There are ads, but I dont find them annoying (you can skip the vast majority of them). Like OML, the design is beautifully minimal, and the background music (should you play with sound on, which I recommend) is great. I hope you guys come out with more games!
