Cozy started as a personal private cloud and app platform, and is now evolving into a universal tool that can help you organize your life and make you more productive by automating routine tasks. But it can also host any client side app you want, including games such as 2048 or esviji.
If you already have your Cozy, you just have to copy/paste this url into the “Install an app from it repository” field in your cozy’s store page: https://github.com/jsilvestre/cozy-esviji/.
Thanks a lot Joseph for this!
You can also read the documentation to create your own applications for Cozy.
