Players can place Towers when they have the required amount of Elixer by tapping on empty structures and selecting the icon that corresponds to each type of tower. Players build as many towers as they can with whatever Elixir they have available and then hit the skull icon to begin an attack. As players progress through the game trying to earn 3 stars in each level they will need to adapt their strategy by selling towers to recycle their Elixir so they can use it to swop towers according to the enemy.
