TOPS an Educational Game Application developed by Dr. Roberto Joseph and his team of students. Based on a commonly played street game named Skelly, TOPS has players move a bottle top around a series of squares containing numbers. As they play TOPS the students will move quickly through a dangerous course, avoiding opponents, always seeking the safety of home bases. Players must use the touch screen to move the bottle top from box to box. They can only progress by using their ability to add, subtract, multiply and divide to slide from box to box ultimately hoping to get to the
center unscathed.
