By completing these Event quests, you will be able to collect Frozen Keys which you can use to open up Treasure Chests. Frozen Keys can also be found around your city from time to time. Open up the Treasure Chests to win the Daily Exclusive or other valuable rewards. Opening up the Treasure Chests will also provide you with Ice Crowns for your counter towards the Grand Prizes. Of course, the better the Treasure Chests, the more Ice Crowns you'll get! And who wouldn't want to have these awesome new buildings in their city?
Event Menu
During the Three Glacier Giants Event you will get two new and exclusive quest lines. But take notice they will only be available for a short time!
The first quest line is the daily Three Glacier Giants quest which will give you random tasks to complete. The second quest line is the episodic Event quest which will give you a specific task. Each quest line will give you Frozen Keys 
as a reward which are added to the Three Glacier Giants menu.
By clicking the Event Menu you will access the event window which will give you plenty of information and allow you to use your Frozen Keys:
- - Shows you the amount of Frozen Keys you have collected and not yet spent.
- - Allows you to buy Frozen Keys with premium currency.
- - Indicates the remaining time for the event to end.
- - Shows you the daily exclusive reward you can get from opening the Treasure Chests and for how long it will be available before it is gone forever.
- - Here you can see how many Ice Crowns
you have and how many you still need to unlock the Grand Prizes. - - Treasure Arcs where you can spend your Frozen Keys and get Ice Crowns plus a random reward in return.
You can also click the 
button to see the help information on the Three Glacier Giants Event at any time!
Frozen Keys
You start the Three Glacier Giants Event with 50 Frozen Keys and each event quest will give you more Frozen Keys as a reward for completing the given tasks.
Also from time to time, Frozen Keys will drop at the outskirts of your city. You can collect them too.
You can then use the Frozen Keys to open the valuable Treasure Chests which, depending on your luck, can also give you more Frozen Keys to spend. Remember that Three Glacier Giants event only lasts for a few weeks, and then you will no longer be able to use your Frozen Keys to get awesome treasures, so don't waste your time!
Treasure Chests
The Treasure Chests hold valuable rewards! You can win Knowledge Points, Rune Shards, Instants, Frozen Keys and even the unique and precious Daily Exclusive Reward. It all depends on how lucky you are! By opening the Treasure Chests you will also get Ice crowns, but remember: The better the Treasure Chest, the more Ice Crowns you get. You can choose between the Small Treasure Chest, the Medium Treasure Chest or the Large Treasure Chest, each containing similar rewards, but with different winning odds.
Ice Crowns
When you open a Treasure Chest, you will win Ice Crowns 
. Each Treasure Chest will immediately give you a specific amount of Ice Crowns, however the bigger the Treasure Chest, the more Ice Crowns you will get.
Ice Crowns allow you to unlock the Grand Prizes! You have three Grand Prizes available, each requiring a certain amount of Ice Crowns. To unlock the next Grand Prize, you will first need to collect the previous one.
After collecting the Grand Prizes, you will find them in your Inventory 
under the Summonings tab.
| Please note: All effects values depend on the chapter you are in at the time you add the buildings to your Inventory. |
Rewards
Each day you will have an unique and precious event reward as the daily exclusive. It can only be obtained by opening the Treasure chests and it is only available for a limited time. Once it's gone, it's gone forever! Be sure to complete the event quests as much as possible so that you can have a chance to win all daily exclusives and make your city a real tribute to the Three Glacier Giants!
This year's Winter Event brings a totally new game mechanic: Set Buildings! These are reward buildings which buff each other when they are placed directly next to each other (in a set). This can mean that their regular production goes up, but it can also mean that totally new productions are added!
