The William Hill Acca Boost rewards you with extra winnings on your football accumulators across 90 Minutes, 90 Minutes 2 Up, Both Teams To Score, and Under/Over Goals markets.
Build any football acca with 4 or more selections, each at 1/5 (1.2) or bigger, and if it wins, William Hill will automatically apply an Acca Boost — increasing your returns by a percentage based on the number of legs in your acca.
Available online and in William Hill shops, Acca Boost offers bonuses from 5% all the way up to 100%, with maximum payouts of £10,000 online and £2,000 in retail.
