A screenshot of Kingdom Rush Vengeance, one of the best tower defense games
Tower Defense games were one of the first genres on mobile to really capture the mobile gaming audience. The biggest reason is because the games almost exclusively feature simple tap controls. Thus, the controls are extremely well suited for touch screens. The genre saw a renaissance on mobile years ago. It’s slowed down quite a bit and some classics in the genre like Anomaly got left behind due to a lack of updtes. However, there are still new tower defense games every year. Here are the best tower defense games for Android.

Swamp Attack

Price: Freemium

Swamp Attack is a tower defense game with a goofy, southern theme. It plays a lot like Plants vs Zombies. Bad guy waves come in from the right side and a hick with a gun battles them off from the left side. You get a bunch of weapons, some decent strategy elements, and 390 single player levels. That should keep you going for a while. Players also tap the screen to shoot weapons so there is an element of control here as well. It's a freemium game, but it really only affects the endgame experience.
