Your job is to clear planes for landing, loading, and take-off. To do this, you must clear a plane for action, which involves clicking on them. There’s a limit to how long you can delay them. Planes will, in time, move by themselves.

To keep the runways clear, you must clear or delay the plane’s movement in the proper sequence. This is essential to preventing collisions. As the game progresses, more planes arrive, complicating matters. There’s no end goal; the game ends when two planes crash into each other.
