Requirements: level 15+

In this event, you open chests and receive guaranteed prizes from each of them.

There are 3 types of chests. Each type of chests requires a different number of keys and brings rewards on a random basis.

1. Standard chest. You need 9 keys to open a chest and you can open 45 standard chests in total. One of these 45 chests will bring you the main reward.
 
2. Enhanced chest. You need 18 keys to open a chest and you can open up to 30 enhanced chests. Enhanced chests contain fewer decor compared to standard chests. One of the 30 chests will bring you the main reward.  The chance to get the main reward is higher in enhanced chests than in standard chests. 
 
3. Super chest. You need 27 keys to open a chest and you can open up to 15 chests. Super chests contain no small decor and more buildings sold for seasonal currency and superbucks in the game shop compared to standard and enhanced chests. One of the 15 chests will bring you the main reward. The chance to get the main reward is higher in super chests than in standard chests.
 
It is up to you to decide what chest to open: standard, enhanced or super chest. 
You do not have to stick to one type of chests, you can open any chest you wish.
 

IMPORTANT! YOU CAN ONLY GET THE MAIN REWARD ONCE!

So, if you, for instance, opened a super chest and received the main reward, you will not be able to receive it again no matter how many standard chests and/or enhanced chests you open.
As soon as you receive the main reward in one of the chests, the possibility to obtain it in any further chest becomes blocked.
You can receive the main reward by opening any type of chests, but you can only get it once during the event.
