The object of J-Ball is to trap J atoms in the smallest possible chambers. You make the chambers smaller with the wallbuilder. Watch the J atoms closely. If only one side of your wall anchors before being hit by an atom, a partial wall is left behind but the cost is one life. You advance to the next level when the walls you build reduce the chamber by at least 75 percent. If you reduce the chamber more than 75 percent, you are awarded points. Each time you advance a level, an additional J atom is placed in the chamber. The more atoms you work with, the higher your points.
