The Christmas 2014 Event (or Winter 2014 Event) was the twelfth major event to be released for The Simpsons: Tapped Out and the third Christmas-themed event. It was released to all players on December 3, 2014, shortly after the conclusion of the Thanksgiving 2014 Event. The Event followed a similar design to the Treehouse of Horror XXV Event in that it was split into two parts, the first running from December 3, 2014 - December 24, 2014, and prizes could be obtained during the first part, by sending characters to do jobs for Presents. The storyline started off with Santa relocating to Springfield and hiring Springfielders to help make toys due to global warming in the North Pole.
During the second part of the Event, from December 24 - January 14, 2015, players had to tap on partying Elves, which roamed around Springfield, and collect Elves in Bottles. After which the player could launch them from the Elf Cannon and 'deport' the Elves. Once launched, the player was awarded Elf Bells which could be collected to win the prizes in the Winter 2014 Part 2 prize track. Cogwheels were unlocked which were used to upgrade the Elf Cannon for "more fire power".
Just like the Treehouse of Horror XXV Event, both parts of this Event had their own special currencies, Presents and Elf Bells. Each currency was collected in their own unique ways and were accumulated by the player to win special prizes from the Personal Prize tracks. Each respective currency was only available for the duration of that part during the Event.
One of the ways to collect prizes during the Event was to complete Santa's Tasks, which were various quests that could be completed once the player built the Elf Cave. Tunnels were unlocked through the progression of the event that contained the tasks required. If all tasks for a specific Tunnel were completed within 24 hours of the beginning the first task, then the player got a bonus of 100 presents. Once the Tunnel's quests were completed, the prize(s) became available in the player's inventory. When all 19 tunnels were completed, Zutroy was placed in the player's inventory as a prize.
All of the new content released with the Event. Note that some of the prizes listed may not be available again once the Event is over.
