Indications are that three small-staking punters were responsible for three of the eight winning tickets of £1,342,599 on the Scoop6 after the bet, which had amassed huge proportions, was finally won after 12 weeks.
Victory for the Alan King-trained Chatez (7-1) in the Betfred Mobile Casino Silver Bowl Stakes at Haydock sparked celebrations, with 122 tickets still standing going into the final leg. Only Grevillea of the 13 runners was not covered by a potential winning line.
Each winning ticket is eligible to play for the bonus fund next Saturday, which stands at a further £5,481,763.
Last weekend, Joe McGuire came within a length and a quarter of claiming just short of £7million for his £8 stake when denied in the last race of six in the bet at Catterick. The total pot in today's win pool was £10,740,797.
One of the betting shop customers is believed to have staked the minimum £2, and the winnings eclipse the previous record for a betting shop success of £1,132,657 by Stuart Boland in 2004, also on the Scoop6.
