But where does that number rank the Scots against the other nations? Scroll through to find out .
Unsurprisingly it's the All Blacks who are top of the charts by some way - Julian Savea scored their last hat-trick in the 2015 quarter-final against France.
The other two time winners are second on the list - Adam Ashley-Cooper's 2015 hat-trick against Argentina was his second ever at a World Cup.
France have scored eight world cup hat-tricks but haven't seen one since Vincent Clerc wen't over three times against Canada in 2011.
The Springboks most recent hat-trick came from scrum-half Cobus Reinach in this year's competition.
Joint fourth with South Africa, Jack Nowell and Nick Easter both scored three in England's 60-3 demolition of Uruguay in 2015.
Only hours after George Horne wen't over three times against Russia, Wales winger Josh Adams also accomplished the feat against Fiji.
Horne's three tries against Russia puts him in illustrious company with Scotland greats Gavin Hastings, Iwan Tukalo, John Jeffrey and Ally Hogg.
Only three Irish players have scored World Cup hat-tricks; Keith Wood in 1999, Brian Robinson in 1991 and Brendan Mullen in 1987.
Level with the Irish, Los Puma's latest hat-trick came in this year's tournament from Julian Montoya against Tonga.
The Samoan's only World Cup hat-trick came in 2011 as Alesana Tuilagi ran in three in a 49-12 win over Namibia.
Like Samoa, Fiji's only World Cup hat-trick came in 2011 also against Namibia from Vereniki Goneva.
2019 hosts Japan scored their first ever World Cup hat-trick in the tournament's opening game against Russia with Kotaro Matsushima the Japanese hero.
In the same match that Goneva scored Fiji's only World Cup hat-trick, Theuns Kotze also crossed three times for Namibia's one and only.
