So the better you play the better defenses you'll get, which enables you to go back and best previous levels in challenge modes and earn more Stars to get even better defenses. Stars are then consumed to permanently upgrade defenses (more hit points, attack points etc.) as well as to unlock heroes. In case player really gives it to the enemy in the 'normal' challenge he'll earn 3 Stars and will be given chance to earn 2 more Stars by besting the same level in two different challenge modes. First there's the 'normal' challenge, where player has to simply survive under the waves of enemy attacks. Players can also buy Gems via IAP.Įarning Stars is a bigger deal. Gems can then be used to purchase from a narrow assortiment of various consumable power-ups that can be used to win the battles. So win or lose you'll still pocket some Gems once the battle is over. In Kingdom Rush players earn Gems by slaying enemy troops. But despite not having restriction mechanics Kingdom Rush does introduce soft currency called Gems and makes exemplary use of the Star mechanics. Kingdom Rush's core loop is that typical for a paid game in the sense that there's no restriction mechanics other than the progressive difficulty of the levels themselves. In the end I do believe that you could at least double the daily revenue of the title and make few millions on a free version for Android with a month or two of development.īefore you continue, play Kingdom Rush on browser

Yet despite being such a great game it has barely hit top 50 grossing chart on iPad. It's actually so good, that I couldn't take my iPad to work cause I couldn't stop playing the game.
