Lots of people are playing TwoDots. The objective is to solve each level by achieving various goals. Essentially, it's a lot like Candy Crush. When you run out of lives, you can purchase more. This game is making boatloads of money. Unlike this blog.
Here's what's better: if you can get a square of the same color and swipe them out, all of those colors will be removed from the board. That becomes the essential strategy for pretty much every level.
There are 85 levels, of which I've solved 42. When I run out of lives, I switch back to FOLT, until I run out of lives there.
Update:By coincidence, the New York Post has a story about this app today! http://nypost.com/2014/06/11/nycs-twodots-gaming-app-crushes-competition/
