Ultimate Glossary for Online Casinos

Online casinos go by many names, including virtual or internet casinos. These are electronic versions of traditional casinos that allow players to gamble and play games through the internet from a computer or mobile device. Because there are some differences between online casinos and traditional brick-and-mortar casinos, people who are unfamiliar with online casinos can often find themselves confused when trying to find a casino that works for them.

To help you understand the types of games you can play and the terminology you will encounter, this glossary features a broad overview of common game types as well as relevant terms and expressions.

Types of Games

There are several different types of games you can play at online casinos. Some will involve just you and the video dealer, but others can include other players so everyone competes against one another.

Baccarat: A type of card game played between a player and a dealer. Each person tries to reach the highest value of the two cards in their hands. Cards from 1-9 are worth face value, face cards are worth nothing, and aces are worth 1. The cards are added together. If the numbers go over 10 when combined (like 7 and 8), then the 1 is removed from the score. So 7 and 8 combined would only be worth 5 instead of 15.

Blackjack: Blackjack is a game where a player tries to reach the number 21 with their cards without going over. Each player is dealt two and can then choose to be dealt more cards to try and get closer to 21. Going over 21 results in an automatic loss. In online casinos, it is possible to play blackjack with bonuses, multiple hands, and more.

Keno: Keno is a type of game where a player chooses a specific set of numbers from 1 to 80. The house then draws a certain quantity of numbers, usually in the form of balls from cages. Payouts are given based on how many of a player’s numbers were chosen. Keno is a simple game, but it’s also one of the easiest to lose depending on the house advantage.

Roulette: In roulette, players place bets on where a ball is going to land in a roulette wheel. For example, a player might bet that the ball will land on red or black, or even a specific number like 17. The amount a player wins depends on how much they bet and what the payout is for a specific combination.

Slots: Slots are a type of game where the player inserts a coin or chip and presses a button to move multiple wheels with different symbols on them. If the wheels land on certain combinations, the player can win money of varying amounts. This is the basic form of gambling in most casinos, and there are many slot varieties.

Video Poker: This is simply an online version of poker where players compete against one another to win money. Most forms of video poker require a certain amount to play, often called the “buy-in.” Typically, online casinos will have a variety of types of video poker to play, including five card draw and Texas hold ‘em.

Terminology

All or Nothing: A term used in certain games where a player will win everything if they have certain cards in their hand. If they do not have these cards, then they win nothing. All-or-nothing games are considered high risk but high reward.
