We had some hands-on preview time with this title a while back, and since then it has finally appeared worldwide on the App Store. We had a lot of positive things to say about this title, and it's definitely one of the more complete puzzle experiences on the App Store.
Totemo is a slight variation of the match-3 genre, and the goal of the game is to clear the board by connecting the lights horizontally of vertically. As the game progresses, you'll find yourself having to connect three in a row or two in a row using the purple star. It's definitely a lot simpler than my explanation, and it's very easy to learn once you get the hang of it.
