Tips for this offer
Be aware that William Hill have different tennis retirement rules to Smarkets, which could expose you to a big loss in the event of a player retiring.
If you are placing your qualifying bet on the 'Match Betting' market, I recommend dutching your bet at another bookmaker with the same retirement rules.
Alternatively, you can place your qualifying bet on the 'Set Betting' market and lay as normal.
Aim to limit your qualifying loss to around £0.75.
You should convert your £5.00 free bet into 75% cash, so £3.75. That gives you a profit of £3.00 on this William Hill offer.
General advice and example for ‘Bet X, Get Y’ offers
Place your qualifying bets at low odds, ensuring you meet any minimum odds requirement. Use the ‘Qualifying Bet’ setting on the Matched Betting Calculator to calculate your lay stakes.
Once received, you can convert any free bets or bonuses into cash. Use the ‘Free Bet’ setting on the Matched Betting Calculator to calculate your lay stakes. It’s best to place free bets at high odds to maximise your profits.
See my ‘Bet X, Get Y‘ guide for a complete walkthrough of this offer type.
General advice and example for dutching
Dutching is an alternative form of matched betting where you match bets at another bookmaker instead of a betting exchange. You can use dutching to place qualifying bets and convert any free bets or bonuses into cash.
Use the appropriate setting on the Dutching Calculator to calculate your back stakes.
See my Dutching guide for a complete walkthrough of this offer type.
