Use the arrow keys (or WASD / HJKL) to slide the tiles. On touch devices, swipe in any direction. Press R for a new game.
Join matching numbers to reach the 2048 tile. Each merge adds the merged value to your score.
Merge two or more pairs in a single move to earn a combo bonus: +50 per extra pair. Chain combos on consecutive moves to push your best combo even higher.
Keep your highest tile in a corner and build toward it. Bigger merges are worth more, and chained combos multiply your bonus — plan moves that clear multiple pairs at once.
