What technology there is behind an online casino

This article explains what are the most common programming languages found in online casinos, the technology behind online slots and live dealers, and also an explanation of a Random Number Generator.

What programming languages are commonly found in online casinos?

Online casinos leverage a variety of programming languages to create engaging and safe platforms for players.

JavaScript, along with HTML5, is critical for front-end development, ensuring that games are accessible directly through Web browsers without the need for additional downloads. For the server side, languages such as Java, Python, and PHP are commonly used, providing robust back-end support to securely manage user data, game logic, and transactions.

RainBet is a prime example of an online casino at the forefront of using modern technology. For its platform, it uses Next.js, a React framework that enables server-side rendering and generates static websites. This choice improves the user experience through faster loading times and better SEO, making it easier for players to find games and play games.

Slot machine technology

Online slot machines leverage advanced software and algorithms to mirror the experience of traditional slots. At their core, they use RNGs (Random Number Generators) to ensure that each spin is completely random and fair, making the outcome of each game unpredictable.

This technology is critical to maintaining integrity and trust in online gaming. In addition, online slots are developed using sophisticated graphics and sound effects created with programming languages such as HTML5 and JavaScript to provide an immersive experience on various devices without the need for additional software.

Live dealer technology

Online live dealer technology bridges the gap between land-based and online casinos by broadcasting live dealers directly to players.

This innovative approach uses high-definition video cameras to capture the dealer and the game in real time, providing a transparent and immersive gaming experience. OCR (Optical character recognition) technology plays a key role, translating the physical transactions made by the croupier into data.

OCR allows immediate online feedback, such as card distribution or the spin of the roulette wheel, to be accurately represented in the game. In addition, live chat features enable interaction between players and dealers, promoting a social feel similar to that of land-based casinos. Secure, fast Internet connections and advanced streaming technologies ensure seamless play and real-time interaction.

Random number generator explanation

A Random Number Generator (RNG) is the digital heartbeat of online casinos, ensuring fairness and unpredictability in games.

RNG generates sequences of numbers with no discernible pattern, mimicking the randomness of manual casino games.

Two types of RNGs are prevalent: Pseudo-Random Number Generators (PRNGs) and True Random Number Generators (TRNGs).

  • PRNGs use algorithms and mathematical formulas to produce long sequences of results, requiring an initial number, known as a seed, to start the process. Despite being deterministic, if the algorithm is unknown, the output appears random.
  • TRNGs, however, derive randomness from physical phenomena, such as atmospheric noise, ensuring true unpredictability.

Online casinos predominantly rely on PRNGs for their operations, given their efficiency and reliability. These systems undergo rigorous testing by independent auditors to ensure compliance with fairness standards.

What algorithm do online casinos use?

Online casinos use algorithms based on random number generators to guarantee the fairness and unpredictability of the game.
