In Case Battles, each prize a player wins is determined through a secure, provably fair process, which ensures each "roll result" is unique and verifiable. This roll result is generated by combining several values into a “seed,” which includes the current EOS blockchain state, a secret server-generated code (server seed), the player’s position in the game (an identifier from 1 to 4), and a unique nonce for each opened case. These values are combined into a single string format like "EOSvalue:serverSeed:position:nonce", ensuring that each roll is specific to each player’s interaction.Once the seed is prepared, it is processed through the SHA-256 hashing algorithm to produce a secure, randomized hash. From this hash, the first 13 characters are extracted and converted into a large decimal number. This result is then divided by 100,000, using modulo to yield a final roll result between 0 and 99,999. This roll result is matched against predefined item ranges, each with specific probabilities, to determine the item that the player wins.Here’s an example of the code that generates the roll result and determines the prize for a player:<pre data-language="plain">/** 
 * Generates a roll result based on the provided EOS, position, and nonce.
 *
 * @param {number} position - The position value.
 * @param {number} nonce - The nonce value.
 * @returns {number} The generated roll result.
 */
generateRollResult(position, nonce) {
 const seed = this.eos + ':' + this.serverSeed + ':' + position + ':' + nonce;
 const combinedSeed = crypto.createHash("sha256").update(seed).digest("hex");
 const rollResult = parseInt(combinedSeed.substring(0, 13), 16) % 100000;
 return { rollResult: rollResult, seed: seed };
}

findWinningItem(rollResult, items) {
 return items.find(
 (item) =&gt; rollResult &gt;= item.range.start &amp;&amp; rollResult &lt;= item.range.end
 );
}
// Fisher-Yates shuffle for multiplier cases
shuffleMultiCases(blockHash, playerIndex) {
 const caseList = [...MULTI_CASES_ORDER_LIST];
 const intValue = this.generateRandomNumber(blockHash, playerIndex);
 const seededRandom = this.seededRandomGenerator(intValue);
 for (let i = caseList.length - 1; i &gt; 0; i--) {
 const j = Math.floor(seededRandom() * (i + 1));
 [caseList[i], caseList[j]] = [caseList[j], caseList[i]];
 }
 return caseList;
}
generateRandomNumber(blockHash, playerIndex) {
 const seed = <code>${blockHash}:${playerIndex}</code>;
 const hash = crypto.createHash("sha256").update(seed).digest("hex");
 return parseInt(hash.substring(0, 13), 16);
}
seededRandomGenerator(seedValue) {
 let lcgValue = seedValue;
 return function () {
 lcgValue = (lcgValue * 9301 + 49297) % 233280;
 return lcgValue / 233280;
 };
}
</pre>This setup uses a provably fair method to calculate each prize, with both the roll result and multiplier case shuffle based on secure and verifiable data.
