Script and roulette algorithm?

Question

PHP

+ - I understand how it works until the moment of choice, everything is different on different sites. Interested mainly in the client part, that is, scripts.
If examples and code samples, then on Node.js, JS, jQuery, PhP please.
Examples:
https://loot.g2a.com/case/147
There are a lot of them on the Internet if you type cs go rulette.
Perhaps there is a ready-made solution or an example of implementation in the form of program code? Please tell me at least an approximate implementation algorithm.

Answer 1

Regarding CS:GO roulettes:
In most roulettes, a bot's Steam account is used, which is a temporary storage of items (during the betting process, the items get into the bot's inventory). On Node, requests to this bot are sent via a steam package. With the bot, there are also some nuances, you need to automate authorization by mob. phone, but it seems that there are already ready-made scripts for this.
You can read about hashes here: https://fungun.net/jackpot/faq.php
But each project can develop its own hashing algorithms.

Answer 2

A web part is being made (most similar projects are being made on Laravel), a NodeJS server is being screwed up, which will be responsible for what thing a person has won, and a Live feed via SocketIO... And that's it.
