You mean mods? Once downloaded, on the world selection screen click the mods button and click the little square to turn desired mods on or off.

I was talking about mod modifiers, such as sky block etc.

Those are called "mutators", you need to buy "adventures pack dlc" and then BEFORE you create world you press this big button "mutators" which is at the bottom of screen and choose which mutators you want.

You can't enable mutators on existing worlds, at least you can't do it without messing with files.

There are mods which modify those mutators so they work differently, but they don't unlock mutators, you need DLC.

thanks to me I thought they were free
