Travis Burns' first Super League try helped Hull KR ease past Castleford to consolidate their play-off place with a 26-22 win on Sunday.
The former Penrith Panther and Manly-Warringah Sea Eagle went over for Rovers as they raced into a 10-0 lead after Michael Dobson set up Kris Welham for the second.
However, Castleford, led by Rangi Chase, fought back to lead 16-14 at the break, with Kirk Dixon, Jake Webster and Richard Owen all going over before the break.
After half-time Hull KR took control with two quick tries from Josh Hodgson and Craig Hall to move ten points clear again, only for the Tigers to respond with a try against the run of play from Daryl Clark.
But the loss of former New Zealand international Webster with an arm injury appeared to affect Castleford and they couldn't complete a comeback.
The other game that had been scheduled for Sunday between Leeds and Wakefield was postponed for the second time in the weekend because of the snow, having already been rearranged due to the cold conditions on Friday.
Meanwhile, Wigan were one of four teams to pull within a point of leaders Huddersfield after scoring 11 tries in the 62-4 demolition of Widnes with Pat Richards among the scorers.
The 31-year-old, who played for Parramatta and Wests in the NRL, got himself on the scoresheet 16 minutes into the second half and also contributed nine goals.
But, for all of Richards' efforts, it was Josh Charnley who stood out most with four tries, while Sam Tomkins helped himself to a hat-trick with Widnes scoring a consolation through Lloyd White.
The Warriors sit second but are level on 11 points with four others including Catalan Dragons, who defeated the Bradford Bulls 30-10 with Louis Anderson among the scorers.
The former New Zealand international touched down early in the second half as the Dragons recovered from being 10-6 down at the break to score 20 points.
Morgan Escare, Daryl Millard, Zeb Taia and Leon Pryce all followed Anderson's lead while Danny Tickle's late goal from a Richard Horne try helped Hull FC draw 18-18 with London Broncos, with Ben Galea scoring Hull's first try.
On Friday,St Helens and Warrington were the two other teams to pull within a point of Huddersfield - the latter defeating the leaders to do so.
Warrington comprehensively outplayed the Giants who managed just a Danny Brough goal in the ninth minute as the Wolves ran out 28-2 winners.
Chris Riley opened the scoring and Brett Hodgson, who kicked six goals, closed it with Stefan Ratchford scoring in either half as Warrington cruised to victory.
And Francis Meli grabbed one of St Helens' two tries in the 14-10 win over Salford City Reds.
Meli touched down just before the hour mark after Ade Gardner scored the Saints' first in the first half with two tries in the last 12 minutes from Liam Foran and Marc Sneyd not enough for Salford.
