0x800

It's 2048, except the board is a hexagon made of hexagons, tiles slide in six directions, and every value is written in base 16. Build 0x800 (2048) to win. Pure vanilla HTML/CSS/JS — no build step, no dependencies, no network, no accounts. A single-page game you can open straight from disk.

Play

Open index.html — no build step, no dependencies, works from file:// and offline.

• Keys: W E / A D / Z C form a hexagon around S (physical keys, any layout). Arrows and numpad work too. U undo · R new game · ? help.
• Touch: swipe the board in any of six directions, or tap the hex pad.
• Click SCORE to toggle HEX / DEC. The help overlay has a board-size selector (7 / 19 / 37 / 61 cells) and themes (auto / light / dark / high contrast).

Develop

node test/run.js      # zero-dependency tests for hex.js, game.js, palette

src/hex.js and src/game.js are pure (no DOM); move() returns a new state plus an events array which render.js turns into the animation timeline. See idea.md for the design document.
