What is a Casino Random Number Generator?

Online casinos use random number generators (RNGs) to guarantee genuinely random outcomes in games such as slots, blackjack, and roulette. Unlike dealer-guided games, where winners rely on the luck of the deck or dice roll, an RNG algorithm determines results based on extensive sequences of up to about four billion independent numbers generated every second.

Sound complicated? We’re here to clear things up and teach you everything you’ll need to know about casino random number generators.

The moment you hit the Spin button on a slot game, a random number generator tells the reels where to land. Likewise, a random number generator shuffles the cards in blackjack and determines the outcome of each card dealt.

RNG software ensures games that don’t feature live dealers remain unbiased and that the results are unpredictable. The casino random number generator is constantly active, churning out numbers even when the game isn’t in use.

To ensure fairness and maintain the integrity of the games, independent third-party organizations such as eCOGRA, QUINEL, iTech, Gaming Associates, BMM Testlabs, and Gaming Labs International (GLI) rigorously test casino random number generators. Online casinos rely on these testing agencies to verify that their RNGs operate correctly and produce genuinely random outcomes. Once testing concludes, casino random number generators with positive results receive certification for fairness.

Reputable online casinos have too much on the line (i.e. their licenses) to risk tampering with RNGs, so you can rest knowing that all’s fair when it comes to these platforms.

All non-dealer online casino games employ random number generators to increase legitimacy and ensure totally random outcomes. Here’s how RNGs operate in different games:

Online slots come in various engaging themes such as Ancient Egypt, magic, vampire hunting, and Indiana Jones-style adventures. They offer thrilling gameplay enhanced by high-quality graphics and immersive sound effects. Additionally, players can enjoy exciting bonus features such as bonus rounds, free spins, scatter symbols, and wild symbols.

A casino random number generator assigns a value to each symbol on the reels. When you hit the Spin button, the RNG selects a random number which determines the spin’s outcome. Stopping the reels early does not impact the outcome of the spin. The game is over the instant the reels start to move.

If it’s your first time playing video poker, experts recommend starting with a low-variance game like Jacks or Better. You need to compare various games’ paytables to find the best odds. Check each paytable until you find one that pays nine for a full house and six for a flush.

When the player presses the Deal button, a casino random number generator determines which five cards will be displayed on the screen. The player selects the cards he wishes to hold before drawing to his final five-card poker hand. The hand dealt is determined by the random number generator.

Seasoned players appreciate online blackjack for its low 0.05% house edge when adhering to basic strategy. Based on computer simulations of millions of blackjack hands, basic strategy tells players the optimal moves to make based on their hand and the dealer’s up-card. While most online games offer a 3:2 payout, it’s essential to verify the payout ratio before playing as some games have a less favorable 6:5 payout that should be avoided.

Rather than human dealers shuffling physical cards, online casinos use random number generators to shuffle cards and determine the order in which they are dealt. Shuffling cards randomly guarantees that every player has an equal chance of winning, ensuring a level playing field. Random number generators are frequently designed to replicate the same odds as a physical deck of cards.

Online casinos offer several roulette variants including American, European, and French. Played with a European Wheel, French Roulette offers the best odds with a house edge as low as 1.35%. European Roulette features a 2.7% house edge and the American version offers a 5.26% house edge.

A random number generator determines where the ball will land in online roulette. It generates numbers from one to 37 corresponding to each pocket on the roulette wheel. Online, the spinning of the roulette wheel is just for show. The winning number is instantly generated the moment a player presses the Spin button.

Millions of poker enthusiasts worldwide enjoy the game for its combination of skill and luck. Online poker variants such as Ultimate Texas Hold ‘em, Casino Hold ‘em, Pai Gow Poker, Three Card Poker, and Let it Ride are played heads-up against the dealer. Unlike traditional poker, in these variants, players place their initial wagers before seeing their cards.

A random number generator is used to shuffle and deal cards in online poker. In Ultimate Texas Hold ‘em, the RNG ensures that the community cards remain unpredictable and free from any discernible patterns. When you press the Deal button in Three Card Poker, the RNG selects three random cards from the deck for both the player and the dealer. Regardless of the poker variant you play, the RNG guarantees fair and unbiased results.

The goal of baccarat is to predict the winner of the hand about to be played. A bet on the banker offers the lowest house edge at 1.06%, although it comes with a 5% commission. A bet on the player carries a 1.24% house edge. Despite the commission, betting on the banker remains the optimal choice. Conversely, despite its enticing 8:1 payout, a tie bet has a hefty 14.4% house edge, making it the least favorable option in baccarat.

A random number generator determines which cards are dealt to both the player and the banker in online baccarat. All cards are assigned a numeric value, and their order is determined by a sequence of random numbers. The RNG is responsible for shuffling, distributing cards, and determining the outcome whether it’s a win for the player, a win for the dealer, or a tie.

Before the shooter rolls the dice, the players place their bets on the Pass Line or the Don’t Pass Line. Ninety percent of players bet on the Pass Line, which means they win when the shooter wins and lose when he loses. When the shooter’s first roll of the dice (the Come Out roll) lands on seven or 11, it’s called a natural and the players who bet the Pass Line win 1:1 or even money.

In online craps, the RNG generates random numbers or sequences that correspond to specific dice combinations. The outcome of each roll of the dice is determined at random by the RNG algorithm. Since craps is played with two dice, two separate RNGs are used in the game.

There are two common methods used to generate numbers:

A casino random number generator doesn’t directly impact your chances of winning, but it makes certain advantage play techniques, such as card counting, impossible.

That’s because the deck is shuffled by the RNG after every hand. RNG-operated games offer transparency, providing the RTP percentages and the odds of winning combinations.

While you can’t beat an RNG, following optimal strategies can significantly improve your odds of winning. Choosing games with a low house edge works in your favor. Additionally, it’s crucial not to overbet your bankroll if you want to stay in the game. Remember that a casino’s random number generator operates like a well-oiled machine, so if you’re experiencing losses, you should blame luck rather than the game.

It’s important to prioritize responsible gambling with RNG games. Here are some ways to stay secure:

Licensed and reputable online casinos, including BetMGM, FanDuel, and Caesars Palace Online Casino, use random number generators tested by independent agencies to ensure fairness. These sites feature robust casino bonus offers for new players and highly rated casino apps that are available for download. Registering for an account only takes a few minutes.
