No, Supercell has no intention of discontinuing or shutting down Clash of Clans at this time. Four new games based on the COC universe have been released by Supercell. It's possible that the company's recent update is a contributing factor in the proliferation of these rumours. It will no longer be able to support a number of devices that have out-of-date software. As announced in a blog post, COC will no longer provide technical support for devices running operating systems older than iOS 11 and Android 5.0. Because of technical issues that are out of their control, they say.
