Trapball is a free puzzle game developed by Gustaf Sörensen for Android devices. In this game, your objective is to build walls to trap the balls. The game is similar to Jezzball, but with a simpler interface and gameplay.

The game is easy to play. You just need to draw lines to create walls and trap the balls. Once you have covered the goal area, you will proceed to the next level. The game has multiple levels, and each level is more challenging than the last. You need to be strategic and plan your moves carefully to complete each level successfully.
