Factory Balls is an interesting cool math game online in which your objective is to interact with various objects to make a move to customize the white balls into painted ones in each level. Drag and drop a ball over the tools or paint to produce the required ball design in each level. Use tools like duck tape, a cover and a color spray paint. In some levels the tools can be hidden so you will have to guess the results and remember them in order to produce the design. If anything goes wrong, move the ball into the bin on the right and start over. You have a limited amount of balls though. Once you will be out of balls, the game is over!
