I keep seeing people talk about how point spreads work in sports when they make their social picks, but I am totally lost. Does it mean the team just has to win the game, or do they have to win by a certain number of points for me to gain more virtual coins in my balance?

am trying to figure out if understanding how point spreads work in sports is actually better for my community ranking than just picking the overall winner. Is there a simple way to use these spreads to grow my promotional points faster and what needs to be done for this? I would be very grateful if you could share this information.
