Swipe up, down, left or right. All tiles slide as far as they can, and two tiles with the same number merge into one. After every move a new 2 or 4 appears. Make the goal tile (2048 on the classic 4×4 board) to win, then keep going for a higher score.
Keep your biggest tile in a corner and build a chain of descending numbers next to it. Avoid swiping in the direction that pulls your big tile out of its corner.
Each game starts with 2 free undos. When they run out, you can watch a short video to get 3 more. You can undo up to your last 5 moves.
No. Each board size keeps its own game in progress and its own best score, so you can switch any time.
