About Marble Run

Marble Run is a simulation game where you build 3D runs and mazes for a marble. Combine wooden and metallic parts to create runs in any shape, and use lifts, vents and other mechanisms to make them cyclical. You can share your designs with friends and test and evaluate runs made by other players.

Frequently asked questions

Steam lets publishers create keys to sell in other shops. Once you activate a key, the game is yours to keep, just like a store purchase.

Disclaimer: CD keys have an inherent 1–2% average failure rate. Check the shop terms for buyer protection info. Steam offers no buyer protection for keys bought in other shops and doesn't refund them.
