Trained by Betfair Ambassador Gordon Elliott, Tiger Roll was given a brilliant stalking ride by experienced jockey Davy Russell who always had the popular eight-year-old in a promising position.
The virtual race, which was uniquely developed to feature the 40 declared runners and riders from the 2018 Grand National field, used complex data algorithms to eventually predict Tiger Roll as the victor of the 2018 Grand National.
Pleasant Company had looked beaten jumping the last but somehow found a second wind and ate up the ground between him and a tiring Tiger Roll only to be denied by the shortest of margins.
The Willie Mullins trained and Malcolm Denmark owned Pleasant Company was 9th in the 2017 Aintree Grand National when ridden by Ruby Walsh.
From the National-winning team of owners Gigginstown House Stud and trainer Gordon Elliott, Monatomic (9/2) jumped into the lead at the second last.
Third was Bless the Wings - another from the all-conquering Gordon Elliott stable - and fourth Anibale Fly under the 2003 winning jockey Barry Geraghty.

When Silver Birch passed the post in front back in 2007, Elliott was a fresh-faced 29-year-old still making his way as a fledgling trainer. "It's unbelievable for Davy Russell - his father Jerry is, I'm sure, very proud watching him at home".
But Pleasant Company lifted off the canvas once more, only to dive and miss. "Past year he made a bad mistake at a crucial stage and that ended it for him".
His David Mullins, who is the nephew of the trainer, said: "I was hoping and praying we'd get there". That's racing and I'm very lucky that I won it two years ago.
Ms Unwin said: "I think it's a really fun day just to dress up, and you know you can wear things a little bit more extravagant, that you wouldn't otherwise get to wear, so I just went for colour".
"The National I have won 1,000 times in my mind".
At a slightly bigger price Ucello Conti would be one I fancy to run a big race.
