How would I make a banner/gacha system

Hello, I’ve looked at some tower defense games on roblox right now and have noticed they have a banner system in them that resets every day or hour.
(Example: Anime Adventures,Toilet Tower Defense,All Star Tower Defense,etc).

I would like to know how they managed to sync up the current banner with every server, as that’s confusing to me.

If you’re confused on what I mean, it’s this. (Toilet Tower Defense’s Version.)

As you can see they manage to have this in every single server, then automatically make the new summoning screen sync to every other server when it resets.

Would anyone know how i’d be able to achieve this? I’m willing to use any methods like HTTP service, i just need a pointer in the right direction.

Probably the best way to do it is generating a random.new object with os.time as the seed, for a more detailed explanation check out the link below.
