How Bonus Bets Work
Sportsbooks offer bonus bets (free bets) as promotions. With a standard free bet, you receive the winnings but not the original stake back. This means a $100 free bet at +300 pays $300 profit (not $400 like a cash bet would).
Maximizing Conversion Rate
The conversion rate is the percentage of the bonus bet's face value you can expect to extract as real cash. Longer odds give higher conversion rates:
- -110 odds: ~47% conversion
- +200 odds: ~67% conversion
- +300 odds: ~75% conversion
- +500 odds: ~83% conversion
Strategy
For the highest conversion, use your bonus bet on a long-odds underdog and hedge the other side with a cash bet to lock in guaranteed profit.
