Regardless of how much you want to win, it is important to remember that you are in a communal gaming environment and must practice good slot machine etiquette. This will help to ensure a positive experience for all players.

For starters, never sit down at a machine unless you intend to play it. Doing so takes up a spot that another player could have used.

This will ensure that you are getting the best deal on your casino visit.
