Over/under bets, also known as totals, focus on the combined score of both teams in a game rather than the outcome of the game itself, which distinguishes them from moneyline and spread bets. Moneyline bets require picking a winner outright, while spread bets involve predicting the margin of victory, creating opportunities for strategy based on team performance versus expectations. In terms of risk/reward, over/under bets tend to offer a different kind of volatility since they rely on overall scoring trends rather than specific team dynamics and performances.
