Random Number Generator: What It Is and How it Works

By Jeff Stinger

In crypto casinos, the Random Number Generator (RNG) is a crucial component that provides fair and unpredictable game outcomes. It generates random sequences in games like slots, roulette, blackjack, and dice. Unlike traditional casinos, crypto casinos use Provably Fair RNGs, allowing players to verify game fairness. Provably Fair, or PF, is the most disruptive element in online casino play, perhaps in the industry’s history. In this article, we dive deep into how RNGs work and the differences between an RNG in a traditional casino and a PF RNG in a crypto casino.

How Random Number Generator Works in Crypto Casinos

Traditional Random Number Generator – The Old Generator Method

  • It uses complex algorithms and seed numbers to generate random outcomes.
  • The casino controls the algorithm, so players must trust the platform.

Not all algorithms are the same in every casino, which makes the RNG in traditional casinos tough for seasoned and new casino players to trust. An old-school online casino may say its random number generator algorithm is fair, but players cannot know for sure if the RNG is fair. Now check out why Provably Fair Random Number Generation (PF RNG) is changing the online casino industry. Only blockchain-based casinos can utilize PF RNG.

  • It uses cryptographic hash functions to generate random numbers.
  • It involves three key components: Server Seed – Generated by the casino, Client Seed – Generated by the player or their browser, Nonce – Increments with each bet

The server seed hash is provided before the game starts, preventing manipulation. So, the hash of the server seed exists before each pull of a slot machine, so to speak. This hash is unique to each game.

After the game, Provably Fair RNGs reveal the entire seed so players can verify the results.

Why is Provably Fair RNG Better than Traditional RNGs?

Casino players always want to play in an online casino that employs Provably Fair RNGs, which means we always want to play in a crypto casino rather than the classic online casino. Check out the top three reasons why Provably Fair RNGs are better than old-school RNGs.

  • Transparency: Players can verify each bet’s fairness.
  • No Casino Manipulation: The casino cannot change the outcome mid-game.
  • Trustless System: No need to rely on third-party audits

Keep reading for an example of a provably fair process. This will give you insight into why casino players should switch from their traditional casino to a crypto casino.

Example of a Provably Fair Process

  1. The casino provides a hashed, or encrypted, server seed before betting.
  2. The player provides a client seed, or the browser generates one.
  3. The seeds + nonce are used to generate the outcome.
  4. After the game, the casino reveals the original seed, allowing the player to verify the randomness.

The Provably Fair Random Number Generator process in crypto casinos ensures fairness, with provably fair technology adding transparency, preventing casino manipulation, and requiring third-party audits. It’s a significant advantage over traditional RNGs, which rely on trusting the casino rather than verifying results. We usually want to bet in a crypto casino to take advantage of true Provably Fair RNGs.
