How free bet conversion works

A "free bet" or "bonus bet" pays only the winnings if it hits — you don't get the stake back. So a $100 free bet at +200 returns $200 cash on a win, not $300. Because the stake is a sunk token, you maximize value by playing it on a longshot (more upside if it hits) and hedging the other side with real cash on a different book. The hedge guarantees a fixed cash return regardless of which side wins.

Conversion rates: at +200/−220 you lock in roughly 65–67%. At +500/−600 you can clear 75%+. The catch is the hedge book's vig and line drift between the two books — the wider the gap, the less you keep. Always confirm both legs are still bookable before placing.
