Bubble Shooter is a video game app that might just be the most popular bubble popping game of its variety. Like other games of this type, the goal is to match three colors in a single connecting formation, and those shapes then disappear from the board. If you make formations larger than three pieces, the entire formation will disappear. The app is entirely free, and it can be played anywhere with or without an internet connection.

This game is surprisingly relaxing when you consider what you're doing. You're basically shooting balls at other balls in the hopes of breaking them, but that simple and never-ending goal is suitable for anyone of any age, which is why this game is so popular.

The game has leaderboards and challenges as well, so you can measure your score against family and friends who also play. As you play and advance through the levels, you'll earn coins, which act as an in-app currency that can be used to buy boosters and other power-ups. You'll have to do more than find the simplest formation in order to win in many cases, so this Bubble Shooter app will test your logical abilities to their absolute limit.
