THIS GAME IS NOT ABOUT PUZZLES! Do NOT download for puzzles. They make you upgrade Keep\Castle and everything in it before you can even get to play the next puzzles. The higher level you get they push you pay in order to get the next puzzles. You only get to do about 10. And they are all the same. If free2play, when you get to a level, can't get any higher without paying, you don't get to even see the new puzzles. When attacked and zero'd expect to spend money, especially from ALL the LAGGING!
