You can get a highscore on Snapchat just by sending and receiving Snapchat messages.
Each Snapchat counts for one point!
What's the point of Snapchat highscore?
It's a technique that digital products use called "gamification".
It encourages users to compete against each other to gain more points, and in doing so, they end up using the Snapchat app more and more - which is great news for Snapchat!
