Frequently Asked Questions
How do free bet conversions work?+
Place the free bet on a heavy underdog (high odds), then hedge the other side with cash at another book. Since free bets only return profit (not the stake), the formula is: cash value = free bet amount × (decimal odds − 1) / decimal odds.
What odds should I look for?+
Higher odds = better conversion rate. At +300 (4.00 decimal), you convert 75% of the free bet to cash. At +500 (6.00), you get 83%. Aim for +250 or higher. Moneylines on heavy underdogs in MLB, NHL, or UFC work well.
What's a good conversion rate?+
Anything above 70% is solid. 75–80% is very good. Above 80% is excellent. Below 65% means the odds gap is too large between books — wait for a better opportunity.
