How to Lower the House Edge in a Casino


A casino is a facility that allows patrons to gamble and win money. The casino may have a variety of games such as card games, dice games, domino games and even a gambling device called the roulette wheel. The casino is usually designed to attract customers through its lighting and sound. Some casinos also offer food and drinks. Historically, many people avoided casinos, believing them to be immoral and demeaning. However, a number of states legalized gambling in the 1980s and ’90s. Casinos have since spread throughout the United States and are found on American Indian reservations.

Every game in a casino has a built-in statistical advantage for the house. The amount of the edge can be low – lower than two percent – but it adds up over millions of bets. It is this money that pays for the elaborate hotels, fountains and replicas of famous pyramids and towers seen in some casinos.

The house edge can be lowered by playing the games with the best odds. However, casinos often make the lousiest-odds games look the most attractive with flashing lights and a dazzling array of colors. This is a tactic known as “enticement.”

Another way to lower the house edge is to learn basic strategy for each game you play. For example, blackjack has an excellent basic strategy that reduces the house’s edge to less than 2%. Some casinos allow players to use betting systems based on counting cards, which can shift the probabilities in your favor even more.
