Playtech BGT Sports saw record turnover for the Grand National, coming from its self-service betting terminals (SSBT).
Playtech announced it had more than doubled the number of bets taken compared to last year’s Grand National, with its turnover rising 135%.
The average amount wagered on the race also increased, rising from £5.46 ($7.13) in 2014 to £7.94 this year.
The supplier recently enjoyed a 300% year-on-year increase in turnover during the Cheltenham Festival.
At the Grand National, the 180-year-old race saw one million more people tune in to ITV Racing’s coverage compared to 2018.
Its peak audience reached 9.6 million, with an average of 5.4 million, accounting for a 39% share of the British terrestrial television market.
Tiger Roll was the main attraction, who became the first horse since Red Rum to win back-to-back Grand National titles for trainer Gordon Elliott.
ITV was in competition with the BBC, which showed the FA Cup semi-final between Manchester City and Brighton & Hove Albion at the same time.
Playtech BGT Sports Senior Commercial Director, Lee Drabwell, said: "We are finding an increasing number of customers both old and new are enjoying horseracing on our SSBTs.
"Having good-quality data at their fingertips and a quick transaction means they don’t have to worry about queues or missing the start of the race."
