I bought the castle, have 986 Cham, 934 Intell, and 936 strengh. I also have over 3million in the bank. I have a macro just keep clicking on "sleep" then "OK". And, since there is interest in the back, I get around 1.2 - 4.0% of my 3mil. Basically, I'm god. Oh, and if your wondering, I'm on day 76823.
I use to play this game a long time ago, and they added stuff since then. Pretty cool.
