I RULE!!!
HERES A GREAT STRATEGY OF SURVIVING:
1.Buy the temple.
2.Be sure that you convert non-stop enemy sticks
3.when you have 50.000 buy a manapool with 40.000 , and the rest of 10.000 are needed to pay the mages (the mages are payed from the remaining money from the last round , not the money you earned from the first round , be sure that you have no more than 50 mages if you have 10.000(1 mage = 200gold)
4:when you have 20.000 remaining money from the rounds you can have 100 mages!!!!!
at level 16 I CONVERTED WITH MAGES kinda 100 enemy sticks XD....follow the strategy and the gmae will be easy as pye!
