I can't remember if I've ever talked about this life-ruining game, but I started playing it about a month ago and I am embarrassingly hooked. It's a super simple design and concept and it's a lot of fun. Plus it's still at that stage where you can look smugly superior at your friends who are still playing Candy Crush and say, "Oh, have you not heard of this game? I guess it's still very underground."
Any other game recommendations?
