Create your own marble machine gadgets. Choose parts from a work bench that contains dozens of pipe sections and animated pieces. Pieces can be easily moved and rotated and snapped to connect with nearby pieces. You can combine up to 100 pieces into a single creation. You can easily adjust the time interval between marbles being released. You can also adjust how powerful the spring is and how much the anti-gravity accelerators boost the marbles uphill. Some pieces have sliding controls so they can be adjusted at run-time. You can design a closed system, that returns the marbles back up to the box where they started, so it could theoretically run indefinitely. Hit Play to watch your creation run. Choose from 4 different preset camera positions, or use the controls to create your own custom view. An additional Marble View will show you what it’s like to travel inside your device. Easily save or load previous creations or optionally Share your creations with friends via email or text messages. Games you share are multi-platform, allowing them to play on another copy of Gadget Creative Challenge running on most popular smartphones, tablets, and computers. Windows 10/11 UWP (Universal Windows Platform) plays on Windows 10/11 PC.
