Crashes constantly, too many ads

The game suffers frame rate issues at the beginning of each round, which can make you lose instantly. It is full of ads, more so than other free games, and they pop up every 3 or 4 rounds, very annoyingly. And it crashes constantly, at least on the Ipad Mini.
Other than that, the game is very addictive and innovative, but until these problems are solved it is not worth it.
