Boost multi-leg sports wagers by up to 200% at Sports Interaction. Learn how the Parlay Boost and SGP+ features calculate extra winnings.
Published:Sports Interaction runs a promotion that adds extra profit to winning multi-leg bets, reaching up to a 200% boost – one of several offers detailed in the full Sports Interaction betting review. You can build these tickets across leagues like the NHL, NFL, NBA, MLB, and European soccer, with the bonus applying directly to your winnings when your ticket hits.
Core Qualification Requirements
The setup is tied to the size of your ticket. Adding more legs increases the extra percentage you receive. To qualify, your slip needs at least two selections, and each individual pick must carry odds of 1.25 (-400) or higher. The offer works on pre-game wagers as well as live bets.
Combining Markets with SGP+
The platform also supports SGP+, which lets you combine a Same Game Parlay with bets or other SGPs from different games on the same slip. In the past, placing a Same Game Parlay meant missing out on parlay boosts, but SGP+ keeps the boost active. When calculating the bonus rate, each separate game counts as one leg on the ladder, no matter how many internal props you added to that particular game’s SGP.
Boost Percentage Ladder
The boost percentage climbs as you add more legs or distinct games:
- 2 legs: 2%
- 3 legs: 5%
- 4 legs: 10%
- 5 legs: 12%
- 6 legs: 15%
- 7 legs: 20%
- 8 legs: 25%
- 9 legs: 30%
- 10 legs: 35%
- 12 legs: 50%
- 15 legs: 75%
- 20 legs: 100%
- 25 legs: 150%
- 30 or more legs: 200%
The bonus percentage steps up incrementally for every pick you add between 2 and 30 legs.
