How digital casino games work: Blackjack, Roulette and Slots explained

Digital casino games are widely available on licensed platforms such as LSB IE, allowing you to play classic titles from home or on mobile devices.

These games are based on software that replicates the structure and rules of traditional casino formats, using certified technology to ensure outcomes are random and fair.

Before you bet casino games online, it’s useful to understand how each game works behind the scenes.

This article explains the key mechanics of three of the most popular digital casino games—Blackjack, Roulette and Slots—and how outcomes are generated in a regulated environment.

Blackjack

Digital Blackjack is a card comparison game played between you and the virtual dealer. The goal is to get a hand as close to 21 as possible without going over. In digital formats, the game uses a virtual shoe, typically containing several decks, and outcomes are determined using a Random Number Generator (RNG).

The RNG randomly selects cards from the virtual deck, simulating a real shuffle. Once cards are dealt, you choose actions like “hit”, “stand”, “double down” or “split” by clicking buttons on the screen. The software then executes your chosen move and updates the hand accordingly.

Winning hands pay according to fixed odds, usually 1:1 for a standard win and 3:2 for a Blackjack. Digital Blackjack does not involve live dealers, although the same game may also be offered in live-streamed formats under separate sections.

Roulette

In digital Roulette, you place chips on a virtual betting layout that mirrors the traditional table, choosing from inside bets (specific numbers) or outside bets (like red/black or odd/even). After bets are placed, the software activates a simulated wheel spin.

Just like in Blackjack, the outcome is determined by an RNG, which selects a number at random from the range available (0–36 in European Roulette). The wheel animation on screen is for visual reference only—it reflects the RNG’s result but does not determine it.

European Roulette is the most commonly offered version in the United Kingdom and Ireland, as it features a single zero, offering better odds than American Roulette, which has two zero pockets. Winnings are calculated automatically based on the type of bet and its corresponding odds.

Slots

Digital Slots are standalone games based on spinning reels. You select your bet amount, choose how many paylines (if applicable) to activate, and press “spin.” Each spin activates the RNG, which selects random positions for each reel.

Outcomes are determined entirely by the RNG, not by previous spins or player actions. The result is then matched to a paytable, which lists combinations and their associated payouts. Some Slots include special symbols such as wilds and scatters, as well as bonus features like free spins or multipliers.

Modern Slots vary widely in design, but all regulated versions must have published Return to Player (RTP) percentages. This figure represents the theoretical average return over time but does not guarantee specific outcomes for individual sessions.

Software integrity and fairness

All licensed online casinos in the UK and Ireland are required to use RNGs that have been tested and certified by independent bodies. These ensure that every game outcome is genuinely random and not influenced by previous rounds, bet sizes or time played.

The games themselves are provided by recognised software suppliers, who are also subject to regular audits. As a result, your outcomes on digital games are not manipulated by the operator and are legally protected under Irish and EU law.
