Sure, here's an implementation of the 2048 game using ball numbers:

2048 Merge Ball Numbers

To play the game, you can use the arrow keys on your smartphone or computer keyboard to merge the ball numbers. The objective is to reach the number 2048 by merging adjacent balls with the same number. The game ends when there are no more empty cells or no more valid moves available.
