Ads crashed the game. It's a game ads called "2248 - Number Puzzle": when it's over the "x" button didn't work no matter how hard I tried to tap it (it even triggered my Google Play Store to open several times). I tried to push the game to background then pulled it back to front, then June's Journey turned into a constant black screen. It crashed. So I had to reboot the game. Then I kept encountering this nasty ads and had rebooted the game over and over again today.
