Xbox One is getting Roblox, the inventive build-your-own-game online experience. It’s free to download, and it will come with 20 curated levels and modes built by fans.

About 20 Roblox games will be available initially, with a tentative release date of Dec. 3, and more will be added next year. Roblox will appear as an app in the Xbox One Store.

Console owners can now swell the ranks of 300,000 existing game makers on Roblox, as long as they have an Xbox One.

Want to easily make your own games and make some money on it? Roblox for Xbox One can help put you on the path.
