Tower of Frozen Waves/LINE

Tower of Frozen Waves is the second special episode of Cookie Run that was released on 21 December 2015. It introduced a new 'level' system seen in games like Candy Crush Saga, where players have to complete a mission in each level before being able to progress to the next. Each stage has 3 different missions. Completing missions will give the player prizes (such as Crystals or even Treasures) and stars, which can be collected and exchanged for more prizes. There are 50 unique stages in total. The leaderboard of this episode is different from standard episodes - instead of showing a numbered score, the leaderboard shows the map of stages and what stages your friends are at.

This episode is the only one to have finite stages - once the player has completed all missions of a stage, the player will exit the tower. A new type of Bear Jelly is introduced, the Ice Bear Jelly. Like previous Special Episodes, Keys are required to play in this episode.

Development
The new episode came first through the Kakao version of Cookie Run on August 11th. It seemed to be a rather unexpected update, although there were rumors of a new season (and likewise, new episode) for the Kakao version of Cookie Run.

On November 27 (ver. 3.3.0), during the release of General Jujube Cookie, players can see a sneak peek of this episode in the Episode Map, but it has yet to be playable - but it was quickly patched out on December 3. On December 21, however, it has been officially released with 50 floors, making it the second special episode in the game.

Before You Begin...
There are several treasures that is strongly recommended to bring when you start your long trek up the tower.
 * When the goal asks you to collect jellies, such as the 3rd mission on Floor 1, bring along some Burning Heat Infused Jellyco or Valiant Firecracker Jelly. They will generate jellies for you to collect. They are also useful for missions that requires you to collect a specific number of jellies.
 * If the mission is asking for you to collect Coins, bringing along treasures that generates Coin Flowers such as Golden Magic Flower Pot and 99.9% Gold Energy Drink will be helpful.
 * Some missions require you to fall into holes a certain number of times. Wonder Donut, Very Wet Drink and Honeymoon Cocktail of Full Moonlight are good treasures to use.
 * Yikes! Some of the missions require you NOT to collide! Burning Heat Infused Jellyco or Valiant Firecracker Jelly will keep the path clear for you.
 * It's time to go FAST! Some of them require you to clear missions under a certain time limit, and going at normal speed will not work on most of them. It's time to gear up with treasures that gives Higher base speed, such as the Vroom Vroom Gold Kiwi Key, Super Spicy Red Hot Chili Drink and Olive Oil Sunscreen. Just watch where you're running!

Episode Summary
''Far beyond the sea, lies a mesmerizing frozen tower that resembles soaring ocean waves. Want to find out the secrets that lay on the top of the tower? Every time you climb a floor, it gets colder and colder... Watch out, because one wrong jump might just freeze you!!''

Floors
This episode contains 50 unique stages, or floors (FL). Each stage has 3 missions to complete. For the beginning, only the first mission will be unlocked. The second mission is unlocked once you've had finished the first mision, and the third mission is unlocked once you've had finished the second mission. For every mission completed, the player will receive a Frozen Star to a maximum of 150 if you finish all missions in all 50 floors. The player must complete at least one mission at their highest floor before being able to advance to the next floor.

Finishing each mission will gave a small prize, while collecting certain amount of Frozen Star will also guarantee another prize. However, both prizes can be only collected once. Both prizes also must be claimed manually in the "Reward" section of each player's Mailbox, and will expire in 90 days if not claimed.

Below are the list of prizes obtained from collecting Frozen Stars: The game also gave away three prizes hidden in question mark, probably coming soon.

Twists
Similar to Ghost Pirate's Island of Coins, each floor from this episode comes for some twists:
 * Cookie's skill, Pet's skill, and Magnetic Aura might be turned off during certain stages. These can be seen before pressing Start.
 * All boosts are disabled.
 * Each floors has a finite end. If you didn't finish a mission before the end of the stage, the gate will not open and the cookie will automatically die regardless of how many energy remaining the Cookie has.

You can still customize for your combination of treasures.

Things to Unlock

 * Special Reward for collecting all 7 Mystery Jewels - Receive Sea Fairy's Crystallized Affection Treasure.
