Parlay betting can lead to big wins by combining multiple bets into one larger bet with higher odds. The strategy is to ensure that every line in the parlay is of value or that the overall parlay's value is drastically inflated, such as with parlay boosts. Using free bets, bonuses, and plus EV bets can generate a massive advantage. While parlays are complex and may require calculations and research, using a parlay builder tool can simplify the process. Although parlays are viewed as recreational, they can offer huge payouts when they win.
