Sportsbooks worldwide increase parlay payouts by 30 percent to attract higher betting volume. Boosted parlays are now a standard promotion in regulated markets such as the United Kingdom, Canada and several US states. The additional value applies across football, basketball, tennis and American football.
Online Sportsbooks Offer Boosted Parlays
Operators such as Rainbet DE include parlay boosts within weekly campaigns. Players placing a combination of three or more bets receive a payout increase if the entire ticket wins. In New Jersey, where online sports betting generated more than $1 billion in monthly handle during 2023, boosted parlays accounted for more than 15 percent of sportsbook promotions.
Football Matches Attract Majority of Boosts
Football dominates boosted parlay promotions. English Premier League matches are among the most frequent selections, with 30 percent boosts offered on accumulators of three or more legs. In Spain, where sports betting turnover exceeded €9 billion in 2022, La Liga fixtures are frequently promoted with similar enhancements.
Examples of football parlay boosts:

Basketball Markets Feature Time Limited Boosts
Basketball markets are a prime target for boosted parlays, particularly during the NBA season. Operators in North America offer 30 percent boosts on tickets of three or more games. During the 2023 NBA Finals, multiple sportsbooks provided enhanced payouts that increased betting turnover by double digits compared with regular season matches.
Tennis Tournaments Include Seasonal Boosts
Grand Slam tournaments are used by sportsbooks to promote parlay boosts. In markets such as Australia, where tennis betting generates millions in turnover during the Australian Open, operators boost winnings on accumulator tickets.

Operators in the United Kingdom, where the Gambling Commission enforces strict rules, block bonus activation until player accounts are fully verified.
