The game is fun to begin with but the upgrades are very expensive for such a basic game... It gets to be very competitive as there are only six layouts for the battles and there seems to be no handicapping and as such you fight opponents who are grossly stronger than you which just spoils the game for all. The developers are also very mean with their free and daily awards which are pitiful in size and quite useless. In summary, not worth spending any money on, but fun for a quick distraction.
