A slot is a slit or other narrow opening, especially one for receiving something, as a coin or a letter. A slot is also a position or assignment, as in a series or sequence of events or in an organization or hierarchy. The term may also refer to a location in an airplane or automobile, as for example the gap between the wing and a high-lift device such as a flap or an aileron, or the position of a face-off circle on a hockey rink.
Many people believe that they can improve their chances of winning at slot games by using various strategies. These include betting systems that change the size of your bet based on past results. Such a strategy is particularly effective during winning streaks since it allows you to increase your bet size while still keeping your bankroll intact.

These benefits will become even more apparent as EUROCONTROL expands its role to cover more regions of the world.
