Your Snapchat score will only increase by sending photo and video Snaps! Text messages sent through the Snapchat app do not count. You don't get extra points for sending the same Snap to multiple users. You need to send a unique Snap to get a point.

How often does snap score go up?

Snapchat Score refreshes each time a user sends or receives a Snap. When a user looks at their own score, it should immediately increase when a Snap is sent or received. For those looking at a friend's Snapchat Score, however, it can sometimes take hours or even days to update.

How much does 1 Snapchat increase your score?

From testing it out, each snap that's sent or received represents one point. Posting a snap to stories also increases your score by a point while texts sent or received and viewing stories aren't counted.
