Provably Fair

Transparency is at the heart of Sundreas. Every game result can be independently verified using cryptographic methods, ensuring complete fairness and trust.

How Provably Fair Works

1

Server Seed

Before each game, a cryptographic seed is generated and hashed for transparency.

2

Client Seed

You can provide your own seed or use a randomly generated one for additional randomness.

3

Verification

Use our provided code to independently verify that the game result matches the seeds.

Crash Game - Verification Code

Verify the crash multiplier using cryptographic hashing to ensure fair and unpredictable results.

How to Use This Code

  1. 1Copy the code below and paste it into a Node.js environment or browser console
  2. 2Replace the seed value with the actual seed from your game
  3. 3Run the code to verify that the result matches what was shown in the game
JavaScript Verification Code
const crypto = require('crypto');

const HOUSE_EDGE_PERCENT = 6.66;

function getCrashPoint(seed) {
  if (typeof seed !== 'string') {
    throw new TypeError('Seed must be a string');
  }

  const hash = crypto.createHmac('sha256', seed).digest('hex');
  const h = parseInt(hash.slice(0, 52 / 4), 16);
  const e = Math.pow(2, 52);
  const result = (100 * e - h) / (e - h);
  const houseEdgeModifier = 1 - HOUSE_EDGE_PERCENT / 100;
  const endResult = Math.max(100, result * houseEdgeModifier);

  return Math.floor(endResult) / 100;
}

// Example usage:
const seed = "your-game-seed-here";
const crashPoint = getCrashPoint(seed);
console.log(`Crash point: ${crashPoint}x`);

Why Provably Fair Matters

Complete Transparency

Every game result is generated using cryptographic methods that can be independently verified by anyone.

No Hidden Manipulation

The house cannot manipulate results in their favor - the outcome is determined by mathematical algorithms.

Player Empowerment

You have the tools and knowledge to verify every single game result, putting control back in your hands.

Industry Standard

Provably fair gaming is the gold standard for online crypto casinos and blockchain-based gaming.
