In short, a minus sign indicates the favorite, showing how many coins you need to use to receive 100, while a plus sign indicates the underdog, showing how many coins you will receive by using 100. And to get started, total points predictions, first to 20 predictions, or first to 30 predictions are a great place to start. I also suggest you to better understand all the markets and formats, check out the WNBA Odds breakdown on Sportzino. It explains all the lines, spreads, and playoff specifics in detail. Also, keep in mind that the season runs from May through September, and the teams have a packed schedule. Does your friend tend to choose favorites, or does he like underdogs?
