Fairness fun fuct

U can check every round id result, use e.g. https://www.programiz.com/javascript/online-compiler/ to run below code

const crypto = require('crypto');
const serverSeed = "PageShouldGenerateNewEverySomeTimeLikePulicSeed";
const publicSeed = "123";
const round = "0";

const hashInput = serverSeed + "-" + publicSeed + "-" + round;
const hash = crypto.createHash('sha256').update(hashInput).digest('hex');
const roll = parseInt(hash.substr(0, 8), 16) % 15;

let rollColour;
if (roll === 0) {
  rollColour = 'bonus';
} else if (roll >= 1 && roll <= 7) {
  rollColour = 'orange';
} else if (roll >= 8 && roll <= 14) {
  rollColour = 'black';
}

console.log(roll);

Seeds are made available by public websites every 24 hours (then they are replaced with new ones), then by providing the data you can check the result of each draw, all using sha256 hashing, which is used in by banks and cryptocurrency exchanges

Page profit fun fuct

Page earnings looks like:

red 7/15 - chances 46,66%  paycheck 2x so page profit is 100% - (46,66%*2) = 6,68 % of all bets

black 7/15 - chances 46,66% paycheck 2x so page profit is 100% - (46,66%*2) = 6,68 % of all bets

green 1/15 - chances 6,66% paycheck 14x  so page profit is 100% - (6,66%*14) = 6,76 % of all bets

You have to subtract rewards or affiliates from your earnings, but it's still
a huge profit bringing in tens of thousands of dollars a day

Features to add

I want to focus on other projects now, so I'm leaving this one, but it can be expanded, e.g. by:

• deposit/withdraw
• support
• affiliates
• small code changes to make it more efficient (removing redundancy)
• better css ( i dont have time to make it perfect )

Maybe I'll add it in some time
