The goal of the game is to get as many footballs through the glass by opening the gate. For each football you manage to get through the glass you're rewarded with a different amount of points, depending on its color. If the football misses the glass, it disappears. When you lose all of your balls, the game is over.
Throughout the levels the difficulty of the game progresses by increased speed of the glasses.
