Bouncy Zone is a mesmerizing 2D simulation game developed by MathJoy. It allows you to set the bounciness, friction, and gravity of a bouncy ball to your preference. You can create simple structures in the game to make a chaotic arena for the ball to bounce in. Once you release the ball, it will bounce around the arena in a mesmerizing way, giving you a feeling of satisfaction and entertainment.

The game also lets you create structures of four different shapes, including lines, rectangles, ovals, and squiggles. You can enable the accelerometer to control the gravity by tilting your device. Another exciting feature of the game is that you can save your favorite zones and play with them later. Moreover, the game uses Google Play Game Services to provide achievements for bouncing the ball a certain number of times.
