App not on home screen? IPhone 5c?

I bought a game a few days ago since I was going into the hospital and needed something to do and it had been showing up on my home screen. Since yesterday it's not visible anymore. However, when I go into the App Store and find the app it says "open" so the game is still installed. I just can't find the icon on my home screen. I tried restarting my phone but that did not help. Any suggestions or ideas are appreciated! Oh, and I have a 5c if that matters at all.

Plug your phone into iTunes and sync it, then go into the iPhone on iTunes and remove the app off your phone like that.
Then go back on to your phone and re-download it.
This should works.
