XSSnake
Online multiplayer Snake where the winner of a game is allowed to execute JavaScript in the browser of other players.
XSSnake is currently in development. The beta release is planned mid 2050.
I will run a public server when this project is stable. If you can't wait:
# 8001: game server
# 8002: static http server which serves the client game files
docker run --rm -p 8001:8001 -p 8002:8002 -it blaiseio/xssnake
open http://127.0.0.1:8002 # in a web browser
