There are currently 3 dimensions in Minecraft that can be accessed without doing anything special. For this quiz, I will include the April Fools dimensions, unadded/discontinued dimensions.
I will use the acronym "CiG" for currently in game or currently accessible without doing anything special.
I also use the acronym "AF" for "April Fools."
I will also use the letter "D" for discontinued.
Tell me/comment if I didn't include something or I made a mistake!
