# 4096

**Stack:** Rust, WebAssembly, TypeScript, HTML

**Playing requires JavaScript and WebAssembly. The rules and controls remain available as text.**

## How to play 4096

1. Slide every tile left, up, right, or down. Equal neighboring tiles combine into a tile worth their sum; a newly combined tile cannot combine again during the same move.
2. Each changed move adds a new 2 or 4 tile to an empty cell. A move that leaves the board unchanged adds no tile and does not increase the move count.
3. Combining tiles adds their new value to your score. Reach 4096 to meet the goal, then choose whether to keep playing.
4. The game ends when the board is full and no horizontal or vertical neighbors can combine. Starting a new game keeps your best score.

Focus the board to use arrow keys or WASD. On a phone, swipe across the board or use the direction buttons. Each swipe makes one move. Fullscreen is available on phones and laptops.

Your board and best score stay in this browser when local storage is available. Clearing site data removes them. Nothing is sent to a game server.

Each grid cell exposes its position and number as text. Keyboard controls work only while the board is focused; direction buttons provide the same moves. The score and game status are announced after a move. The victory animation respects reduced-motion settings.
