Netizens are testing themselves with this 'K-Pop Boy Group Bingo' being passed around on online communities on how much they know about boy groups! 

The difficulty level? HARD! See if you can fill in each of the spaces below with the correct artist/group related to the images. Even if you can correctly guess a good number of the spaces below, remember that "bingo!" connects 5-spaces in a row horizontally, vertically, or diagonally!

Some netizens commented after trying it out, "I only got 4.. the YG artists..", "Can't get bingo at all..", "I know a lot, but I still can't get bingo", "I honestly don't know any of them..", "Why is it that I only see WINNER..", "I can tell NCT because the letters are there", "I can tell SF9 because it's written right there keke", "How could I not know so many?? I thought I knew all the boy groups out there", "Who is the lip shape??", and more!

How many did of them do you know, and can you make bingo?
