Released at the end of 2014, Mojang revealed they would stop development of the game way back in June of 2015. They committed to keeping the servers running until at least July of 2016, though they’ve clearly lasted much longer than that.
As part of the announcement, Mojang also revealed that they are working to make the Scrolls server software public, allowing the community to host their own servers and continue playing online. They said they can’t guarantee this will happen, but that they have “high hopes that we’ll be able to do this in the next few weeks or months.”
As a final goodbye, a community tournament will be held on February 11. Additionally, Mojang developers will be online playing Scrolls with its players on February 9.
