Provably Fair Games

WHAT ARE PROVABLY FAIR GAMES?

Players expect fair gameplay from an online crypto casino. It is understandable as nobody wants to be cheated, especially when playing on real money. That’s where Provably Fair games stand out from all other casino entertainment.

Provably Fair gambling lets players verify game outcomes themselves, without relying on third-party checks. The verification can be done in just a couple of clicks.

At 7BitCasino, you can enjoy Provably Fair games from the best gaming software providers. BGaming is the first developer that has integrated the Provably Fair solutions into its online games. We strive to make all players feel confident about the fairness of their gaming experience on our site.

HOW PROVABLY FAIR ALGORITHM WORKS

The Provably Fair algorithm involves three major components:

  • Server seed (comes from the casino side)
  • Client seed (generated through the player’s browser)
  • Nonce (a number that increases with every subsequent bet)

The Provably Fair algorithm works like this: before placing a bet in a slot or another game, you receive an encrypted hash with a server seed. Then, you place your bet and click the “Spin” button.

After the spin, you can check whether the game result is fair. Click the “Verify” icon in the Provably Fair widget to see whether the cryptographic hash matches the one shown before the game started.

The brilliance of the Provably Fair algorithm is that neither a casino nor a player can change the final hash code. If this happens somehow, you will simply get a hash code different from the initial one. The Provably Fair system protects both players and casinos. It helps ensure that no third party can influence the round result.

PROVABLY FAIR GAMBLING AT 7BITCASINO

Provably Fair algorithms vary from game to game. At 7BitCasino, you can play Provably Fair card games, slots, dice, and Roulette with Bitcoin and other cryptocurrencies. Below, we explain how they work with specific examples.

PROVABLY FAIR BITCOIN ROULETTE

  1. Provably Fair Roulette operates using the Mersenne Twister algorithm, a random number generator used for these types of casino games. This algorithm uses a computing model for the Bitcoin Roulette to define that the wheel will rotate and stop at a random position. Simply put, it ensures that the wheel stops at a random position.

  1. You may select a number from 0 to 36. The Result+Secret hash is shown before the start of each round. Random numbers generated by the Mersenne Twister algorithm are hashed using the SHA-256 algorithm. A player can add an extra input to the wheel rotation by choosing a number from 0 to 36 or using a randomly selected number.
  2. After the ball in the Roulette wheel stops, you will see the result generated by the server on the screen. Use the "Verify" button to compare the generated hash with the hash shown in the pre-betting stage. They must match.
  3. You can track the hash shown before the start of the game and the client seed. You will also see an additional field 'Final Result'. It shows the decoded encryption that verifies the outcome of the game. It indicates that the gameplay outcome was fair.

PROVABLY FAIR CARD GAMES

  1. The “Secret” is a number that is generated by the server and used for the hash. We use a method known as the Fisher-Yates shuffle to generate the shuffled deck. It is like picking a number out of a hat in such card games as Bitcoin Poker, online BTC Baccarat, and crypto Blackjack.

  1. We use the Mersenne Twister algorithm to generate random numbers for the Fisher-Yates shuffle, which helps create a randomized deck. It is the top standard of shuffling techniques in Bitcoin card games. The shuffled deck is called the “Result”.
  2. A player sees a “fingerprint” of the shuffled deck and the Secret value. This fingerprint is generated by hashing the data with the SHA-256 algorithm, allowing players to verify the game outcome themselves.
  3. When the game is over, compare the Result+Secret, the fingerprint/hash code, your chosen position/client seed, and the Final Result. These values should point to the same deck, with one version cut at the player’s chosen position.

PROVABLY FAIR SLOTS

  1. We generate a reel model for each reel in Bitcoin slots. The reel model is created as a list of tiles in the order they appear. Then, a random stop position is generated for each reel using the Mersenne Twister algorithm, which produces the Result for the slot round.

  1. A player makes a bet and starts the game by clicking on “Spin”. There is an option to add an extra push to each reel by specifying a particular number from 1 to 9. By opening the Provably Fair widget, a player will see a ‘fingerprint’ of the spin and a random number (Secret).
  2. This unique fingerprint is created by hashing the data with the help of the SHA-256 Hashing Algorithm. It forms a one-of-a-kind hash code for that exact spin of the slot reel and Secret seed, which you may use to verify the final outcome.
  3. At the end of the game, you will observe Result+Secret, a hash, your client seed, and the Final Result of the game. At this stage, you may determine whether the spin outcome matches the fingerprint.
