Free bet & matched betting mechanics & rules
Matched betting uses mathematical hedging between a promotional bookmaker bet and an opposite exchange lay position.
Payouts are determined by multiplying the unit stake by the cumulative price of each winning selection or combination line. If any selection is scratched or declared non-runner/void, standard rules settle that leg at neutral odds of 1.00.
Worked example: Free bet & matched betting
For a $25.00 SNR free bet backed at 5.00 and laid at 5.20 with a 2% exchange commission, placing an optimal lay stake of $19.61 locks in $19.22 guaranteed profit (76.9% cash retention) regardless of the match outcome.
Always check bookmaker maximum payout caps and race terms before placing high-volume system bets.

CALCULATOR QUESTIONS
Free bet & matched betting questions
How does a void leg affect a free bet & matched betting?
When a selection is void, postponed, or scratched, that specific leg counts as a 1.00 multiplier (money returned for that leg), and the multiple bet rolls down into the remaining folds.
What is the difference between unit stake and total stake?
Unit stake is the amount wagered on each individual bet or line. Total stake equals the unit stake multiplied by the total number of bets in the multiple or system wager.
Are gambling and betting winnings taxed?
Taxation of sports betting winnings varies by country; consult your local tax authority or revenue service.
