The lingua franca of programming games. Drive colonies, bots and hacks with the language you already know from the browser. This page focuses on games where JavaScript is part of the actual play loop: you write scripts, solve puzzles, control bots or build systems instead of only reading a lesson.
Start with Screeps, Bitburner and Screeps if you want code puzzles, learning and mmo / rts. The mix currently leans beginner and advanced, so use the ratings and difficulty labels to choose a first game that matches your comfort level.
For learners, the useful question is not just “does this game support JavaScript?” It is whether the game gives feedback you can reason about: a bot decision, a failing puzzle, a resource loop, a layout rule or a simulation that exposes what your code did wrong.
We keep the list narrow on purpose. If a game only mentions JavaScript in a side feature, it belongs in the full catalog, not here. The goal is to help you find practice where the language matters to the core loop, with enough context to compare options before opening each review.
