It's called Dots, a simple puzzle game loosely modeled on the popular game Bejeweled, which has been around since the days of regular feature phones with color screens.
Dots is insanely addicting. You'll be hooked after one round. Take our word for it.
Here's how it works:
You connect dots of the same color with a swipe. You only have a minute to clear as many dots as you can. (No diagonals!) They disappear and bring in new ones.
If you can complete a square, all the dots on the board of that color will clear out, giving you a bunch of points.
The more you play, the more dots you earn. When you have enough dots, you can buy bonus items like extra time.
You can link the game to Twitter and Facebook and compare scores with your pals.
