Can someone tell me how to get rid of this drop down box?

I’ve found a new game called “4 pictures, 1 word.” I’m playing on my desk top. It has a couple of ways to give you a clue, like you can play just the first letter, or get rid of letters that aren’t part of the word. However, whenever I try to use one of them I get this annoying drop down. I finally shared the app on my fb, and it released me to use one cheat, but when I tried to use another, it dropped down again but the fb option was ghosted.
I noticed that off to the side it said, “Play mobile version,” so I tried to click on that but nothing happened.
