How canvas-tetris Works
canvas-tetris is built with web technologies and delivered through this page in an embedded frame. When you press play, your browser downloads the game's code and assets — a few kilobytes to a few megabytes — and runs them locally at full speed. All the processing happens on your own device: input goes straight from your keyboard and mouse to the game, and rendering happens on your GPU. That is why browser games like canvas-tetris start instantly and feel just as responsive as downloaded ones.
