I'm not that great in chess, yet it seems to me when I play the challenges, the game says "CHECKMATE", when according to me, the game was NOT. Please make the app NOT close the screen automatically at the end of each challenge?! Instead, allow the player to close the screen themselves. To me, I hate it when it just says CHECKMATE, and then immediately closes the screen and goes to the next ad! I would like to see with my eyes whether the game was really in CHECKMATE or not. Otherwise it's great!
