Pocket Marble Runs is a free iPhone game developed by monois Inc. that allows users to create their own marble runs with ease. The app is designed for everyone, allowing them to create fun devices similar to those featured on marble runs (chain reaction machines). The longer the straight line on the screen, the more devices users can choose from.

To create a path, users simply trace the screen with their finger. They can then lift their finger to create a simple device and tap the device to swap it for another one. The program is easy to use, making it accessible to all ages.

One of the best features of Pocket Marble Runs is the ability to change the angle and zoom on the camera, allowing users to see their device from different perspectives. Users can also turn sound effects and music on or off from the options on the top right of the screen. Additionally, device shadows can be turned on or off, which is recommended for users with smartphones that show low performance.

Overall, Pocket Marble Runs is a fun and easy-to-use app that allows users to create their own marble runs and experiment with different devices. The developers plan to add more devices in the future, making it even more exciting for users to create their own unique runs.
