Q:

"Make game out of something" meaning

I've been reading a sentence as follows

The man carried the parcel in a funny way, he was actually making a game out of carrying the parcel.

I first thought the meaning is "Doing something in a funny, amusing way". But it was written at the starting of the sentence. Then, I found nothing so good on the web. I know the meaning of make game of. Please help.

A:

"make game of X" is an entirely different expression than "making a game (out) of X" . 

"make game of X" , as your link suggests, makes X a subject/target of teasing/abuse.  (atlhough, as brought up in comments, I do not personally find that a commonly heard expression - though I think I would understand it that way - perhaps it's a turn of words from back when "handicap" meant more what it does in golf? )
making ~a~ game ~ (out) of ~ X" .  ~transforms~ an activity into a game(as in a contest created for the purpose of amusement).  Informally the "out" might sometimes be omitted but it's meaning is still suggested.
