Dressing up

At certain levels your anthill will get a different look. But you can also build up a collection of different skins to give it a more fancy look. Even if you don't want to put on these skins it is still worthwhile to collect them, because they give buffs that are in effect by just owning the skin.

Each week you can earn skin fragments in the event called Force of Life/Nature/Desert ... etc. If you have a perfect week getting to lv 20 you will have 100 fragments and can buy 1 skin. If you are not so lucky you can just save up the fragments till you have enough.

Go to the queen and click on the button to the right to open the screen where you can choose the skins. You can browse through the skins to see what buffs they give and what you need to buy them (click on the button "source" for that). Some skins can only be bought from packs or certain events.
Choose the skin you like and buy it. Activate it to make it part of your collection. Now you can choose if you want to wear it or not. As soon as it is activated the buff will be in effect.

By spending the skin fragments you will also gain experience points for your hill. The level you reach will be shown by a number of stars above your hill. These levels will also give you buffs. You can spend fragments directly to gain experience, but do NOT use this option. It is always better to buy a skin, because it will give you the same experience points AND the buff of the skin.
