Goal: slide tiles until two matching numbers collide, and get all the way to 2048.
Swipe (or use arrow keys / WASD) to slide every tile on the board as far as it can go in that direction, all at once.
- When two tiles with the same number collide, they merge into one tile worth double — your score goes up by that new value.
- After every move that shifts anything, a new tile (usually a 2, occasionally a 4) appears in a random empty spot.
- Reach a 2048 tile and you win — but the board doesn't lock, so keep sliding for a higher score if you want.
- It's game over once the board is completely full and no two neighboring tiles match anymore, so there's no move left that does anything.
