The update includes festive holiday music (think lots of jingle bells and updated remixes on classic holiday tunes), along with new floors that can be built onto the top of your tower. These floors include Holiday Apartments, that are full of Christmas trees and wreaths, along with Arctic Apartments that give Bitizens a home in an icy igloo of sorts.
In addition, Santa and Elf Bitizens will now start visiting your tower and filling its floors, while your existing characters will start posting some festive holiday-themed BitBook entries in the game's continuous nod to Facebook wall posts.
What's more, the game's elevator has been decked out in candy cane stripes and the lobby to your tower is full of Christmas trees, lights and more.
This Christmas update will likely disappear shortly after Christmas comes and goes in the real world, so make sure to update as soon as you can to experience all of the Christmas fun in your own tower.
