A game about writing code like a dinosaur


  • User picks a language (presently only Go is supported)
  • User is presented w/ 2 panes; editor and live feed to their code being executed
  • User makes changes to get code doing what it should do


Not actually sure what the challenges will be yet; I’m thinking multiplayer (e.g sockets) type things; e.g.:

  • Two players need to exchange some messages with each other
  • Two players need to complete a set of calculations (over a series of messages) and each player can only see the odd or even half of the steps
  • Two or more players need to develop a decentralised chat system (discovery etc) without knowing who’s out there
  • Same as above, but now there are adversaries (also players) actively trying to hinder the other players

I might try and include some sort of in-game chat and hope people don’t use it to cheat; but maybe there’s a hard mode for extra points where the in-game chat is disabled (so the implication is that step one is discovery of your team mates e.g. using multicast, validation that they’re not adversaries in some way and all team chat is done with code written in the session).



  • Frontend makes a GET request to the backend to be allocated a session
  • Frontend mounts Shell component that gives the live feed of the gotty session (just as an iframe)
  • User makes edits in Editor component
  • Editor component text POST’d to Backend
  • entr in Backend re-runs code process
  • Shell component in frontend continues to display live feed


  • Containerise everything (right now it runs natively)
    • Probably Docker Compose w/ private networks (no internet access) to limit exploitability
  • Put an Nginx reverse proxy in front of it all
  • Ability to relate sessions together in a game
  • Recording for all interactions for a game
  • All the actual gamification stuff
    • Identity / single sign-on
    • Lobby
    • Scoring

How to run it




go run cmd/main.go


npm ci
npm run start

How to use it

Once you’ve got the services up and running, navigate to http://localhost:3000/ to see the frontend.

You can pick the language you want to play with from the buttons; alternately you can navigate straight to that language via URL; e.g. http://localhost:3000/rust.
