Simple games for Android are pretty popular. They are great games to play when you are in need of wasting some time, maybe at the doctors office, waiting in the car, on the subway, or even flying across the country. Many of these games are great because they don't need an internet connection to play the game. Always good for being on the subway or being on a plane where there is no internet. This game called Pop the Lock is pretty unique because it uses your memory to crack the lock. Basically what you're doing here is tapping in sequence to crack the code on the lock in your game. There are multiple locks in this game too, and an endless amount of levels available for cracking locks. Pop the Lock is made from Simple Machine, who creates some pretty simple but very fun games for Android (as well as iOS).
Pop the Lock also has support for Google Play Games. Allowing you to get the achievements when playing the game, it will also save your progress and there are leaderboards so you can compete against your friends and play even more. There's not a whole lot to Pop the Lock, you're basically attempting to crack the lock that's on your screen and that's about it. Obviously each level gets a bit harder as you level up. The UI of the game is pretty simple as well, showing you the level your on in the top left corner, along with settings and Google Play Games in the right corner with the lock in the center. Pretty simple, yet gives you everything you need in that UI.
This game is free, and there are no in-app purchases available - although that could change as we've seen that happen with other apps before. Many people are loving the game, but not loving how addicting it is. So be ware that the game can be pretty freaking addicting - sort of like Flappy Bird was. You can pick up Pop the Lock from the Google Play Store today, it works with Android 2.3.3 Gingerbread and higher.
