A 4-0 away win over Camanachd Cup holders Lovat put champions Newtonmore top of a Marine Harvest Premiership table which has five clubs, half its total strength, all on seven points and separated only by goal difference.
Kinlochshiel threw away a chance to go top on their own when they conceded a late equaliser at home to Lochaber.
Kyles beat Skye 2-0 at Tighnabruich and Kingussie edged Glenurquhart 4-3 at the Dell to join the deadlock at the top.
The fifth side on seven points is previous leaders Oban Camanachd, who had no game, and of the five contenders, Kinlochshiel and Kingussie have played two extra games.
Glen MacKintosh got Newtonmore's only goal of the first half and Iain Robinson and Chris Sellar made it 3-0 before the hour mark. Robinson completed his double in the final minute to round it off.
Jordan Fraser put Kinlochshiel ahead early at Balmacara and it looked as if they were going to hold on to top the table until Lachie Campbell equalised for Lochaber with five minutes left.
Kyles left it late against Skye and the game was into its last 10 minutes before Roddy MacDonald made the initial breakthrough and Gordon Whyte got Kyles' second soon after.
Kingussie cashed in on a second-half collapse by Glenurquhart, who were 2-0 up after 12 minutes thanks to David Smart and Neale Reid. James Hutchison pulled one back and Fraser Heath made it 3-1 to Glenurquhart at half-time. However, Hutchison with his second and Rory MacGregor put Kingussie back on level terms. Thomas Borthwick then got Kingussie's winner in the penultimate minute.
Lovat are just one point adrift of the top five while the remaining four sides, Lochaber, Skye, Glenurquhart and, still seeking their first point, Fort William, look in danger of being cast adrift.
In the National Division, Beauly and Kilmallie began the season among the favourites for promotion, but both dropped further points. Kilmallie drew 1-1 at home to Inveraray, who now only trail leaders Glasgow Mid Argyll on goal difference, while Beauly lost 1-0 to Caberfeidh in Strathpeffer.
The Camanachd Cup made a belated start when Inverness went all the way to Bute only to go down 2-0 in their preliminary round tie, Iain MacDonald getting both.
An Aidan MacIntyre double helped Oban Camanachd to a 4-0 away win over Col Glen in the GCC Celtic Society Cup, the South Senior Championship, where Glasgow Mid Argyll's Craig Anderson got two in their 5-1 home defeat of Oban Celtic, who had scored first.
