How to have case opener to save the items you've won?

So far I have a case opening system.

It picks an item blah blah blah

So, I have a scrolling frame that has a frame for each item that's in the case and I want to make it when they win to have it make the frame visible on the scrolling frame once they win it but the problem is to save it as visible when the rejoin any ideas?

if you don't understand something or want me to explain something further please ask.

So, you know how to tween, some basic math functions, understanding of roblox lua, yet you dont know of datastore, or wiki tutorials. I seriously doubt you scripted this yourself. Datastore
