Online Casino Odds

The world of online casino games just keeps on growing. Being able to play all of your favourite slot and table games from a mobile device with theScore Bet is a game changer. Now, it's possible to have a unique casino experience from just about anywhere in the world. With that being said, there are some things to know before diving in.


Both casino odds and gambling odds are explained in simple terms in this helpful guide. From winning odds variance to the house edge, your online casino journey starts here.

The house edge explained

The house edge refers to the percentage an operator typically takes off the top on a slot or table game. This can be calculated by subtracting the house edge from the total amount of money (100%) spent on a specific game by all players. For example, if a particular slot game has a house edge of 4% then that means the return-to-player (RTP) percentage is 96%.


Simply put, you would receive roughly $96 (at minimum) for every $100 you spend on that game. The house edge exists to ensure the casino is able to consistently turn a profit in spite of some big wins by players.

Online slots return to player (RTP)

An online slot's RTP percentage is the amount that is typically paid back to all players. RTP is calculated by subtracting the house edge from the total amount of money spent on the game. For example, if an online slot's RTP percentage is 94%, then you can expect to receive about $94 for every $100 you spend on a particular slot game. A quick trip to our casino slots page will help you further understand this as well as other interesting information.


A slot game's RTP is set by the software engineers when a game is made, with high-end RTPs ranging from 93-96%. Slots operate using random number generation (RNG) software. RNG simply refers to the system within a slot game that churns out the numbers indicating whether a spin wins or not. It's the best way to keep things fair as each spin outcome is unique.

Blackjack odds

Blackjack is one of the most popular table games of all time, but learning the finer points of how to play blackjack can take some time. Once you've decided on how much to wager, you will receive two cards.


The dealer will also receive two cards, one face up (dealer up) and one face down. The goal is to beat the dealer by getting as close to 21 as possible without going over. For example, if your cards equal '20' and the dealer's cards equal '19', you would win the round. 


In order to beat the dealer, it's important to understand the meaning of house odds and bust probability. The house's odds of beating you depend on the face-up card that the dealer initially puts down.


Each card has a different bust probability, with lower-valued cards usually having a higher bust rate than higher-valued cards. To learn more visit one of our blackjack casino pages here at theScore Bet®.


Similarly to online slots, a house edge is deducted from the total amount of money spent at the table. Several factors can affect this number including the amount of decks being used and whether or not the dealer hits or stands on a soft 17. In blackjack, the house edge is usually no higher than 0.5%.

Baccarat odds

Baccarat has always been a fairly popular table game. Admittedly, there is a bit of a learning curve when it comes to how to play baccarat. Before each round, you place a bet on one of three outcomes: banker win, player win or tie. The odds will vary depending on which result you have wagered on. Other factors such as the number of decks affect baccarat odds as well. Remember to keep the house edge in mind as well, as it also varies based on your bet.

Games are typically played with eight decks, although single-deck and six-deck versions also exist. Side bets are also permitted at some tables, allowing bets on more unique outcomes than the main three. Visit one of our many baccarat casino pages for more information on this classic casino game.

Roulette odds

Roulette is often used in conjunction with other words to describe a risky scenario and for good reason. Pick your number(s), stake your wager and enjoy the action. Use theScore Bet as a dependable resource to learn how to play roulette. Explaining gambling odds depends on a lot of different factors such as bet type and whether you're playing American or European Roulette.


For example, the odds of winning a single-number bet (35:1) are much longer than winning a four-number bet (8:1). Luckily, there isn't much disparity between American and European Roulette odds. To put things in perspective, the largest roulette odds gap would be on even bets and it is only 1.2%. Don't be afraid to consult our best roulette tips guides so you're up to speed with all the latest tips and tricks.


Another thing to consider is the house edge. In American Roulette, it's almost always around 5.26% whereas European Roulette only takes about 2.70%. Don't hesitate to stop by one of our roulette casino page for more information.

Live dealer poker odds

Live dealer poker was one of the first table games to ever go online. The most popular live dealer poker games include 'Three Card Poker' and 'Ultimate Texas Hold'em'. In these two versions, you are competing directly against the dealer as opposed to other players. Learn all about this and other iconic table games with our casino table games page.


Evidenced by the house edge, your odds of winning are better in Ultimate Texas Hold'em (99.47 RTP%) than they are in Three Card Poker (96.63 RTP%). Before playing, it's important to know how each possible hand ranks and what the odds are of achieving them. Learn this and other key pointers from our poker tips guide.

Craps odds

Craps has been popular for a long time, with the earliest adaptations tracing back as far as the 1700s. Live craps had a tougher transition to the online gambling scene than other table games since it involves dice rolling. The dealer rolls for you in online iterations, with one of the best being the live craps game developed by Evolution Gaming.


As one of the leading software providers for table games, leave it to Evolution to give the people what they want. For example, one of the best parts of craps is the community aspect. The chat feature in Evolution's version of craps brings back that authenticity people love. There's even an 'applause' button. It also mimics the aesthetic of a 1920s speakeasy, where craps really took off.
