Why?
With "Cookie Jam" someone apparently tried to jump on the successful Candy Crush train. That would be okay as long as the implementation is in order and you play the "copy" does not look too much. But Cookie Jam one sees the same and immediately the great model. "Cookie Jam" is just like "Candy Crush" up, but not as well implemented.
For me, the game crashed twice and stayed several times depend, in part, the screen just stayed black, it was nothing more ... and: The game has no "off" button. One can not quit right then.
On the pitch, the game itself is often incredibly complacent. If you want to scroll back and forth, that lasts forever or not the point. It comes partly no longer out of a game, even when you press X's ...
Therefore: Structured like Candy Crush! But the game runs just miserable - at least on my Kindle.
