When you play, you'll have a chance at one of the following, listed in pairs based on rarity:
- Spinning Top Game (Common)
- Ornament Shop (Common)
- Gift Swap (Uncommon)
- Elf Abode (Uncommon)
- Winter Sporting Shop (Rare)
- Jolly Apartments (Rare)
Again, you'll receive one prize for free (I, for instance, won the Ornament Shop), and can then try your hand at earning more items for 20 City Cash each. There's the possibility of receiving duplicates in the process of going for one of each item however, so keep that in mind.
There doesn't look to be an official ending date for this edition of the Mystery Game, but I wouldn't expect it to remain too long after Christmas itself comes and goes. Keep in mind: it's very likely that attempts at this Mystery Game will go on sale at some point before the game vanishes entirely, so if you have the patience to wait for a bargain, feel free to do so. Just don't wait too long, or you might not end up with any items at all!
