HBO

HBO dropped a second trailer for "Game of Thrones" season seven on Wednesday, teasing several massive battles. But that's not all.

There are also 12 new character posters for the season. HBO sent fans on a scavenger hunt to discover the posters online. All you have to do is tweet #WinterisHere along with an emoji to @GameofThrones. But not just any emoji will do the job. 12 specific emojis will unlock each of the character posters.

If you're finding yourself stumped, don't worry. The INSIDER team put our heads together, along with a little help from some clever Thrones' fans, to unlock the new posters of Dany, the Starks, Littlefinger, and more.

Keep reading to see which emojis unlock each new poster. If you haven't seen the new trailer yet, you can check it out here.

You can't have "Game of Thrones" without dragons. Naturally a dragon emoji ???? will unveil the Daenerys Targaryen poster.

The snowflake emoji ❄️ makes the most sense with the winter theme, and it reveals none other than Jon Snow.

Of course the rest of the Starks have their own posters, too. The wolf emoji ????) will unlock Sansa's poster.

The wolf emoji is a close stand-in for the Stark direwolf sigil. We spotted @Applesonica tracking down the Sansa poster.
