If you are good at math you will see that only half of your clan’s attacks will count (we will talk more about that later regarding strategy). Therefore, our clan will get credited with 3 stars. What do I mean? If I attack base 1 and get 1 star and you attack base one and get 3 stars, your attack and only your attack will count as it was the single best attack. The one single best attack on a single base will count. Your clan wins based on the number of stars your clan won at the end of the battle.
