The first and one of the most well-known sports betting and casino strategies on how to win is the martingale system. In its basic variant, each time you lose a bet, you should wager double on the next match. This way, whenever you win, you cover all your previous losses and gain money for the next bet.
Whereas negative (-) odds tell you what you have to bet on the favorite to win $100, positive (+) odds tell you how much you'll win for every $100 you wager on the underdog. So, a team with odds of +120 would payout $120 for every $100 wager.
