Alright so I know a lot about football, basketball, and baseball. Favorite teams being the Cleveland Browns, San Diego Padres, and Sacramento Kings. I will be going to Vegas on Wednesday(march 6) and would really appreciate if someone could explain to me how betting on sports works. I always see sports books but those scrolling charts just look complicated as hell. I have no idea what an over or under is. What is the minimum you can bet? If I bet 20 dollars on the Kings to beat the spurs does that mean I win 40 dollars. I'm just confused as hell. Really wanna get into sports betting. I know I'm a complete noob, but thanks in advance to anyone that can help me out here.
