Your Snapchat score can only go up one point at a time. Why? Because Snapchat score/Snapchat hiscore is simply a counter for every Snapchat message you send or receive.
Every time a new Snapchat gets sent or picked p by your phone, you highscore goes up by one.
The other catch is that you're only awarded one point if you send the exact same Snapchat to multiple recipients (although everyone that receives the message should get 1 point each).
