Simple and fun, this Android game puts players in control of a small, floating square called a “quad” to navigate around a grid. The aim is to pick up bonus items on the board by making your way over the grid and avoiding what feels like an ever-increasing number of enemy quads, which can take you out with one collision. Users have the option of controlling by tap or by using gesture controls as they bob and weave between enemies. The game includes three playing modes, including an “experimental” one where every point you earn slows your enemies.

It is not a flashy or terribly sophisticated game. But QAR 2 is mesmerizing and easy to pick up for a “few minutes” that can quickly turn into the better part of an hour. Free, for Android devices.
