Numlingo

A number-recall game for language learners

Numlingo drills active recall of numbers in the language you’re learning: 60 seconds to translate as many randomly generated numbers as you can, as accurately as you can. Play solo, or join a multiplayer lobby for your language and race others.

Real-time communication is powered by the Colyseus multiplayer framework which is a wrapper around Express.js. The client and server establish a web socket connection under the hood for communications.
