Darts fans had to pick their jaws up off the floor thanks to amazing achievement from Rob Collins.

Collins, 45, claimed a 4-3 victory over Adam Lipscombe on Friday in the MODUS Super Series - but that wasn't what fans were talking about. In the game, with Collins 2-1 to the good, he managed what's know as a triple Robin Hood.

In darts, a Robin Hood is when the player makes a throw and the dart lands directly into the back of another dart that’s already on the board. Collins amazed fans when he achieved this feat twice, leaving a chain of darts on the board.

Luke Littler darts fans can back 'The Nuke' in Premier League with his playing shirt

Luke Littler fans can now buy the 17-year-old's playing shirt to support him as he continues to demonstrate his talent in the Premier League.

The darts sensation was only 16 when he wowed Alexandra Palace at the World Darts Championship (WDC), despite a final loss to Luke Humphries.

The Nuke will continue playing against seven of the best dart players in the world — Humphries, Michael van Gerwen, Gerwyn Price, Michael Smith, Nathan Aspinall, Rob Cross and Peter Wright — in a mini-tournament in a different city every Thursday until the final in May.

"Genuinely didn’t believe this was possible until I saw it happen right in front of me," one fan replied. While a second shared: "Pretty sure I’ve never seen or heard of this ever happening before!"

"How did his opponent not even react to that," a third joked. And another added: "What happens after I ask the genie for three perfect darts..."

Collins has sunk his first dart into the treble 20, before landing the next two darts into each other. Some fans, on social media, questioned why the resulting score was on 60, the standard treble 20, and not 180.

Because only one dart was in the board, that's the only score that counts as in order for any dart to count for a score, the tip of the dart must come into contact with the dartboard, and must stay in the board.

Others argued that it was actually a double Robin Hood, as only two darts had completed the feat. One of the broadcasters picked up on this, saying: "Oh my word. I don't think I've ever seen a double Robin Hood." However, he was then corrected by his commentary partner: "It's the triple Robin Hood."
