In some casinos if you want to take a brake from the slot machine but you want to come back to the same machine, you have the opportunity to ask a slot attendant to hold your machine. The nice think to do is to offer him a tip for this service.

When you ask an attendant to stand by your machine it is better for you to don't leave your credits in the machine.

When on a chair in front of a slot machine you find a coin cup, in most of the cases it means that the machine is being saved for another player. In some casinos you will find also put on the chair for the same reason an ashtray or a jacket. The polite thing to do is to respect this sign and look for another machine.

If you are a person who likes playing at more than one machine at a time you should be considerate of the other players in there. When you see that there is too crowded you should play at only one machine. In many casinos you will find signs for this situation that state 'One machine per player during busy times'. A good etiquette would be to respect them.

If you are chating with your friend who stays at the machine next to you but he is not playing, that is not a nice thing to do. Slot machines should be free for players who want to play.

There are situations when a player may forget his club card in the slot after he played. If you are the person who finds it you can place it on the top of he machine or next to it because most of the times the player who forget it there may come back for it.

The final tip for slot etiquette that I can give you is to don't do to other players what you won't like it to happen to you and always have fun.
