Elemental 4 is a recreation of the game Elemental 3 made with modern web technologies. In the game, you combine multiple "Elements" to create new elements, such as Earth + Air = Dust, and so on. If a combination does not exist, an automated crowdsourcing system is in place to create it.
Like the original, I had to shut it down due to technical issues, but in it's run time, over 14,000 elements were created through a grand total of 300,000 votes, with over 5,700 element owners (unique users who sent the first vote for a new element). Since I shut it down due to issues with my backend, it has been forked for more continuations of the game. At some point, I would like to write a blog about all the things I learned making this, as well as the problems I encountered during development and during deployment.
Since most of it's issues were backend design, the front-end lives on nearly unchanged on Nv7's Elemental 7, though I wish it could have allowed for zero-latency responses like my version did; but it runs overall better than my backend.
Another implementation of Elemental I heard was fun was the Discord-based Elemental on Discord (EoD). I've have nothing to do with this project, and it is only being listed here for completion sake.
Join the Elemental Community Discord to discuss about Elemental-style games, as the small community with them has done a lot for the genre. This was the server I initially made for the game, but I do not control it anymore.
