[Mehrexam] Making roblox's hardest puzzle for a prize!

Hi there!

I’m Dara and I’ve came to the thought of making roblox’s hardest puzzle (named Mehrexam) for the prize of 5000 robux!
I was wondering if this would be against roblox’s terms of service or not. It will NOT be done on roblox’s website but it will be done within the roblox community.
Also, if it is allowed , does anyone have feedback on how to properly promote the puzzle?
This exam is inspired by Cicada 3301 but it is nowhere nearly as hard as that.

I dont really think it will be against roblox tos but im not an expert so its best to hear from someone that knows more
