Goal

Slide and merge numbered tiles to build a tile worth 2048.

How it works

• Swipe up, down, left or right on the board (or use the arrow keys). Every tile slides as far as it can in that direction.
• When two tiles with the same number touch, they merge into one with double the value: 2 + 2 makes 4, 4 + 4 makes 8, and so on.
• After every move, a new 2 (or sometimes a 4) appears in an empty square.
• Each merge adds the new tile's value to your score.
• The game ends when the board is full and no move can merge anything. Undo takes back your last move.
• Reaching 2048 wins, and you can keep going for a higher score.

Tips

• Pick a corner and keep your biggest tile there. Many players use the bottom-left.
• Mostly use two directions (for example left and down), a third when needed, and the fourth only when forced.
• Build a chain of falling values along one edge, such as 256, 128, 64, 32, so each merge flows into the next.
• Don't chase small merges in the middle of the board. Keep it tidy.
