Okay, if you don't understand the title, or even if you do, please read this body. I will be referring to: https://www.speedrun.com/Make_a_Cake_Back_for_Seconds#Complete_Cake - in this thread. So, if you click it, you can see that it is on the Complete Cake category, which isn't necessary to say really but I am anyway. As you can see, there are the Mobile and PC categories. If somebody could post how to do this with an image of where I go, that'd be preferred however just telling me should be fine. More specifically, the Retro Obby category I'd like to know how to do. So, in the Retro Obby category, you can choose PC, then Damage or No Damage. You can also choose Mobile, then if you took damage. Anyone know how I do that, as well?

Thanks, Doge Master.

I guess your talking about subcategories. To do these, just click on "Edit Game" at the left side and scroll down to "Extra variables/subcategories" and press "New Variable". Now click on "Use as subcategory". If you click on the name ("World subcats" in my case) you can change the name of it, this is only visisble to you. In your case it would be something like "Platform" or "Device". Next to it you can select in which categories you should be able to select it. Below it, click on "New value" to create a value users can choose from, in your case something like "Mobile", "PC" and "Multiplayer". To add rules, click on "No Rules", if you want to change them, just click on it.
