Although Snapchat’s explanation of Snapscores remains as vague as possible, the easiest way to increase your score is to simply use the app. Since its release, sending and receiving pictures and videos on Snapchat has been the tried and true method for increasing your score, and the more people you communicate with, the higher your score will be. Because devoted users previously looked for any way to “cheat” the system, Snapchat implemented a few changes, including that whoever you send a snap to must open it for your score to increase.
You can also no longer send the same snap to multiple people and expect your Snapchat score to increase for each user who receives it. You need to send unique pictures and videos to various friends and users if you want that imaginary score to be as high as possible.
Receiving and opening Snaps will also boost your score, so you want to use the app as much as possible. If you don’t have that many friends still active on the app, there are plenty of online communities to join that are geared toward sending daily Snaps to increase their scores. If you’re taking that route, just be careful; internet anonymity makes people do all kinds of strange things.
