If you’ve ever played casino games, you’re probably aware that the casino will always come out ahead. This is because casinos have built-in advantages, such as a house edge, which represents the average gross profit they earn from a particular game. However, you should keep some things in mind when playing in casinos.

First, casinos can be difficult to navigate. The rooms are typically large and empty, with no signage or helpful tour guides. There are dealers and pit bosses, but if you’ve never been in one, it can be difficult to figure out where to go. Luckily, most casinos have security guards on site, so you don’t have to worry about getting caught.

Another thing to remember when visiting a casino is that personal electronic devices are not permitted. You cannot use a cell phone while you’re sitting at a table, and the walls of most casinos make cell phone reception impossible. This means you must walk outside to use your phone. Similarly, cell phones and pagers are not allowed in sports books.

Another important part of casino etiquette involves tipping. Since casino dealers are paid minimum wages, they expect tips when you win. While tipping isn’t necessary or compulsory, it’s polite to give a small portion of your net winnings. Some dealers suggest tipping up to 10% of your net win, but this is not necessary. Most casinos pool tips and split them fairly between everyone.
