One of the most popular things to do on Snapchat is to earn a Snapstreak. This occurs when you and one other friend have sent Snaps (not Chatted) to each other within 24 hours for at least three consecutive days. One you've passed the three-day mark, then you and your friend will receive a fire emoji next to your names.
Bitmojis are not only a good way to personalize your Snapchat account, but also a really fun Snap addition to play around with. A bitmoji is basically like your little avatar, letting you design your mini-self whichever way that you desire.
There's nothing more fun than unlocking a hidden Snapchat filter and beating everyone to that perfect first selfie. So when a new filter comes out, like the current Game of Thrones one, it's always interesting to see how the filter will turn out to be.
