The words can be spelled horizontally, vertically or diagonally.

If you click on any of the balls, you will notice that 7 balls will be darkened, 6 on the outside and 1 in the middle.

The ball in the middle controls the movement of the 6 balls that are darkened.

In order to move balls around you have to keep clicking on the center ball for the letters to fall where you want them to go.

When you have a word that's been put together correctly the balls will turn green, if they are incorrect, the letters will be red.

To move a letter to another location,just change the center ball so that the letter you want to move falls on the six balls that are highlighted.
