French question

I was looking at the M&M's website in French when I came upon a phrase of whose meaning I was unsure. Here is the phrase:

Attention, le trivia game est pour l'instant en anglais, histoire de corser les choses !

"The trivia game is in English for now, story of to intensify things?"

Does that last part mean something like "just to make things more difficult/challenging"? Or...?

Thanks in advance!
