Stupid Zombies is an arcade game along the lines of 'Angry Birds' in which you substitute the birds with a shotgun that you use to shoot all of the zombies on each level.
The goal of each level of Stupid Zombies is to kill all of the enemies. In order to do so, you have to shoot your weapon so that you either hit the zombies directly or so that you can start a chain reaction that gets rid of all of the undead.
You will have hundreds of different levels to put your skills to the test and where you will make bullets bounce off of dozens of different surfaces. In addition, you can use explosive barrels and other elements that make it so that your bullets can do away with lots of zombies at once.
Stupid Zombies has simple, fun and addictive mechanics that are ideal for short games. It doesn't have the best graphics in Google Play, but it doesn't really need them, either.
