Worst algorithm ever that is used in a game . In builder base it is even more utter disappointing that whenever the troops or builder battle machine is going towards town hall to attack even though they break walls , they don't even go inside and attack it . Instead they turn all the other way around and avoid the player to earn a star . This is all selfish style which demands players to get upset and play the game .. even there are plenty of videos showing that the game has too much errors .
