William Hill gives new customers £30 in free bets when you deposit and bet £10. Register using promo code R30, deposit at least £10, and place a bet at odds of at least 1/2 (1.5). Once that bet settles, you’ll receive 3 x £10 free bets to use on any sportsbook market within 7 days. Key restrictions: Most eWallets, Neosurf, Paysafe, , ecoPayz, and William Hill PLUS Card deposits don’t qualify. We have compared a full list of PayPal betting sites and their offers if you prefer using this eWallets as your payment method. Your qualifying bet can’t be cashed out – if you cash in early, you won’t receive the free bets. Free bets must be used in full – you can’t stake a portion, and any unused amount is voided.
As you’d expect from one of the best betting sites William Hill also has separate welcome bonuses for casino games and poker. Each has different terms, so we’ve broken down the key details you need to know below, along with how to qualify for each offer.
William Hill’s casino offer gives new players 200 free spins on Big Bass Splash when you deposit and stake £10. One of the best things about this offer compared to those at other casino sites is the lack of wagering requirements. Register using promo code BBS200, opt in, deposit at least £10, then stake £10 on Big Bass Splash. Refresh the game to claim your 200 free spins, each worth 10p. You have 72 hours to use them before they expire. Winnings from the free spins are capped at £30 maximum and are added to your main balance once all spins are used – you can then withdraw them or use them on other games. Important: Apple Pay, PayPal, and Paysafe deposits don’t qualify.
The latest William Hill poker offer gives new players a £100 bonus plus a Twister Discovery Pack when you deposit £10. Make your first deposit or transfer of at least £10 to your poker account and opt in to claim the offer. The Twister Discovery Pack includes 7 tournament tickets worth €6 total – 3 x €1 Age of the Gods Twister tickets and 3 x €1 standard Twister tickets. The £100 bonus money is released through a two-stage redemption system using WHPoints, which you earn by playing real money poker. You have 45 days to redeem the bonus before it expires. The offer also includes bonus spins with 40x wagering requirements, a maximum redemption of £20, and a 14-day expiry. Important: like most poker sites you must opt in to claim this offer, and it’s limited to one per customer.
William Hill’s ongoing offers lean towards football and towards improving bets you were going to place anyway, rather than handing out free bets for signing up to something. Some apply themselves automatically while others have to be switched on in the betslip or claimed from the promotions page, so it’s worth knowing which is which. The promotions below run on the sportsbook and the casino.
William Hill boosts the winnings on football accas automatically, with no opt-in and no minimum stake. You need two or more football selections, each priced at 1/5 (1.2) or bigger, on the 90 Minutes, 2 Up, Both Teams To Score or Match Over/Under Goals markets, and it works pre-match and in-play. The ladder pays 3% on a double, 5% on a four-fold, 10% at six selections and 50% at fourteen. The step worth knowing about comes at fifteen, where the rate doubles from 50% to 100% in one move before climbing to 200% at twenty selections or more, so the headline figure belongs to accas far longer than most people build. Boosts apply to your winnings with the original stake taken out.
The Bet Builder Winnings Boost works the opposite way round to the acca boost above: nothing is automatic, and you see exactly what you’re getting before the bet goes on. Build a football Bet Builder on a qualifying match with three or more selections at total odds of 3/1 (4.00) or bigger, then open the Rewards section of the betslip and apply the Bet Builder Winnings Boost to it. The betslip redraws with the improved odds and the potential return shown, so you can judge whether the bet is worth placing rather than finding out at settlement. Stakes are capped at £20 of real money for the boost to apply, which keeps it pointed at ordinary betting rather than large single stakes.
Bonus Drop Boost gives you one free disc a day to drop into one of three slots, and the day of the week decides whether you’re guaranteed anything for it. From Saturday through to Thursday the disc either lands on a win symbol or it doesn’t, so six days out of seven you can play and come away with nothing. Friday is different – William Hill calls it Boost Day, and every eligible player who takes part receives a prize, with the possibility of an additional Friday Boost on top. Prizes come in three shapes: free plays on particular games, a bonus usable on named slot or table games, or cash. The cash is the one to hope for, because it goes straight to your main balance and can be withdrawn immediately.
Ten free spins a month, free to claim and open to everyone. The spins are worth 10p each and run on a game William Hill selects for that month, which changes on the first of each month and is shown on the Vegas promotions page. You claim by clicking through on that page, and the offer resets once per calendar month. The 24-hour clock is where this one bites. You have a day from claiming to use the spins, and it isn’t simply that leftovers expire – if you don’t use all ten inside the 24 hours, the winnings from the ones you did play are forfeited along with them. Use the full ten and any winnings drop into your main balance, withdrawable as cash.
