Teaser bets offer several potential advantages, such as increased chances of winning by allowing bettors to adjust point spreads in their favor, which is particularly useful in close matchups or games involving key numbers. This flexibility can make it easier to cover spreads, especially in sports like football and basketball where scoring is predictable. Teasers also encourage bettors to combine multiple games, potentially leading to higher payouts than straight bets if successful. However, there are notable disadvantages, including lower payout odds compared to straight bets, which can diminish potential profits.
