Balls is a very easy skill game.
You can control the white ball using the arrow keys, press the Up arrow key to move up, Down arrow key to move down, Left arrow key to move left, Right arrow key to move right. You must keep your white ball stay on top of the blue box.
Attention, the grey balls will automatically knock the white ball, so you must keep moving the white ball. If you leave the blue box, the square of the box will become small, if you move on the blue box again, it will become bigger again, and game continues.
Be careful; don’t leave the box for more than 2 second, or else, you will lose.
Your score shows on the middle of the blue box.
