After watching a 3Blue1Brown video on prime number spirals, I had the idea to create a massively multiplayer online checkbox game. The game is simple: you can check or uncheck a box, and the state of the box is shared with everyone else playing the game. The game is built with JavaScript and WebSockets on the client side, and FastAPI for the backend.

There's a fun surprise if the game is completed. It will be interesting to see how the game evolves over time as there is an entropy mechanic to slowly uncheck boxes.

I found it interesting to make something that looks nice but is essentially pointless, partly inspired by One Million Checkboxes.

Play it now!
