Towers

Towers are the main objective in Blox Royale, mainly being the three buildings you need to destroy.

Mechanics In-Game
You and your opponent have three towers each, and you'll have to use your cards to destroy towers. Towers, when approached by an enemy troop, will start shooting said enemy troop and will not change troops until the troop is dead. This makes it devastating when your tower is locked to a tank whilst getting whooped by glass cannons like Jane Doe and Engineer Noob, which deals damage incredibly fast.

Another thing to note is that Towers are basically high HP buildings, since they can; be effected by Status Effects; act as support; act as defense; etc.

Towers decide if you win a match or not. Having more towers than your opponent after three minutes means that you win the match whilst the opposite is also true. Of course, destroying all three towers will make you automatically win.

Defending
Tower Defending can range from the tower killing troops itself such as its capability to two-shot Explosive Noob, to complex techniques like distraction (attacking troop distracted to tank whilst tower chips away health).

Attacking
Tower Attacking is the art of destroying towers, whether that be a cheap trick like Engineer Noob on the other lane and/or a very planned out push.
