Calculate exact lay stakes and profit for qualifying bets and free bets. Minimise losses on qualifiers, maximise profit on free bets.
Stage 1 — Qualifying Bet: You place the minimum qualifying bet required to trigger a free bet offer. You lay this at an exchange to cover both outcomes. The small loss (typically €0.50–€3) is called the "qualifying loss" — the price of unlocking the free bet.
Stage 2 — Free Bet Extraction: Use your free bet as the back stake and lay at the exchange to lock in 70–90% of its value as guaranteed profit. This is where the real money is made.
The closer the back and lay odds, the smaller your qualifying loss. Aim for a difference of less than 0.15 between back and lay odds. Use odds matching software to find close matches quickly.
