Joshua Kimmich has scored late to save Bundesliga leaders Bayern Munich from defeat at home to Cologne, while an Andre Silva double helped second-placed RB Leipzig to a 6-1 thrashing of Schalke.
Free-scoring Wolfsburg, meanwhile, thumped Hertha Berlin 5-0 and Hoffenheim drew 2-2 at home to VfB Stuttgart.
Cologne needed only four minutes to take the lead at the Allianz Arena, Ellyes Skhiri breaking the deadlock after Julian Chabot's header turned into an assist.
Bayern were poor throughout, but grabbed a 90th-minute equaliser when Kimmich picked up a pass from Dayot Upamecano and unleashed an unstoppable strike.
"It's annoying because of the timing, but it's OK. We go home satisfied with the point," Cologne coach Steffen Baumgart said.
"The performance is something we can be proud of."
Leipzig - who played out their own 1-1 draw with Bayern last week as the Bundesliga returned following the winter and World Cup break - set the tone early against Schalke.
Silva broke the deadlock in the seventh minute with a fierce strike from just outside the area before Benjamin Henrichs added a second eight minutes later. he Portuguese striker completed his brace in the 44th.
Silva scored again in the 44th minute and the visitors concluded the first half with a goal from Timo Werner, his first since the ankle injury that ruled him out of the World Cup in Qatar.
"It felt really good to start a game again," Werner said.
"I'm pleased that I'm playing again and celebrating the wins with the team again."
Schalke pulled one back shortly after halftime through Soichiro Kozuki but Leipzig crowned their performance with a stunner from Dani Olmo in the 83rd and a strike from Yussuf Poulsen in the 89th.
"I can only apologise to the fans," Schalke coach Thomas Reis said after his team's lacklustre showing.
Wolfsburg also scored early, through Mattias Svanberg, on their way to demolishing Hertha 5-0. Maximilian Arnold, Jonas Wind, Ridle Baku and Omar Marmoush completed the scoring.
The result follows a 6-0 win over Freiburg at the weekend.
