JavaScript Tetris

Jake Gordon’s real HTML5 Tetris implementation: compact state, a fixed-step loop, a Canvas board, and a DOM score panel.

Small code, complete system

The production keeps its board model intentionally small: pieces are bit patterns, the loop accumulates time, and the renderer only paints settled and active blocks.

This is the real Arcade document and runtime, not a visual imitation. Package files are embedded inside the frame so the production remains local and deploys as one HTML file.

What it demonstrates

Provenance note: Installed from ~/sanzcloud/projects/arcade/site/games/tetris/index.html. Inlined the production statistics helper and board texture; removed the Arcade lobby, telemetry, and vendor run wrapper. Game code is otherwise retained.
