At the same time, make sure your initial £10 stake is on odds with a minimum of 1/2 and no less. So, logically, take a punt on something within this week, and use your free bets freely until the 30-day expiry date arrives. For example, if you bet on Arsenal v Spurs, you must wait until such North London Derby finishes for your free bets to be in your account - so don’t panic if it isn’t in your balance straight away!įor this reason, it’s wise to place it on a bet within 30 days, as the 30-day expiry date will prevent you from claiming your free bets. To claim these four £10 free bets, first, the £10 minimum stake must conclude. These bets will be credited in four £10 free bets, meaning the £40 is split into four bets of £10 to be used within a 30-day period after staking the first £10 bet. The world-leading bookmaker is offering £40 in free bets when a new customer stakes £10 with this sign-up offer upon joining the bookmaker. However, please do note that this offer is valid for mobile/tablet devices only! William Hill’s sign-up offer is one of the best on the market for both bettors who are new to sports betting and those who are simply seeking some free bets for their next punt.
