Online Casinos – House Edge, Variance, and Comps


Online casinos, also known as Internet casinos or virtual casinos, allow people to play casino games over the Internet. These sites are one of the most popular forms of online gambling. Here, you’ll learn about House edge, Variance, and Comps. Using this information, you’ll be better able to choose your casino game and maximize your winnings.

Common casino games

Common casino games include roulette, blackjack, video poker, and slots machines. The game of roulette has become a popular favorite with online gamblers due to its predictability and simple mechanics. Although roulette is a game of chance, the house edge is low, which makes it a game that anyone can learn to play.

House edge

The House Edge is an important element of any casino. This figure helps the casino cover its costs while still remaining profitable. The House Edge is calculated by comparing the average payout to the average return in a game. Using this information, players can determine which game offers the best chances to win.


Variance is a statistical term that describes the differences in the chances of winning a particular game. It is an important concept in casino games, because it helps players understand the dynamics of a game and how to choose the best strategies. For example, if you play three different slot machines at different casinos, the final results will probably differ. Understanding variance will help you decide which games are best for your bankroll.


The best way to increase your casino comps is to be a loyal customer. Casinos will often offer their customers free drinks, meals, and even hotel rooms in exchange for spending a specified amount of money. Sometimes, they will also offer tickets to concerts or events. While this may seem like a generous gesture, it is designed to encourage higher spending and generate more profit for the casino.

Las Vegas Valley

Casinos in the Las Vegas Valley are thriving businesses. Revenue from gaming accounts for 43 percent of the casino industry’s overall revenue, while the rest comes from rooms, food, and beverages. The valley is also home to the oldest continuously operating hotel in the country, the Golden Gate in Downtown Las Vegas, which opened in 1891 as the Hotel Nevada. The city also has the seventh busiest airport in North America, McCarran International Airport. The average annual rainfall in the Las Vegas area is about four inches.


The casino business in Macao is under threat from a trade war between the United States and China. President Donald Trump recently tweeted that he would levy tariffs on $300 billion worth of Chinese goods. China responded by letting its currency plunge. As a result, U.S. stocks suffered their worst losses of the year. This led to a drop in gaming revenue in Macao. VIP baccarat revenue fell more than 15 percent. However, Macao remains the world’s top gaming jurisdiction. The region brought in $37 billion in gaming revenue in 2017, a number that exceeds Nevada’s total gaming revenue of $11.9 billion.


You must be at least 21 years old to gamble online in Singapore. However, many offshore casinos do accept players who are 18 and above, but you should have proof of age to use the casino. The accepted currency at Singapore online casinos is the Singapore dollar, which is a small currency relative to major world currencies. However, most online casinos also accept US dollars, UK sterling, and Euros. Regardless of the currencies used, most online casinos will offer good exchange rates.
