Title favourites England tore apart Samoa 92-3 in Northampton for their biggest-ever World Cup win and go two for two in the pool stage.
Australia failed to advance with England when they played out a 31-31 thriller in York with the United States, with both sides remaining in quarter-final contention.
Canada, eyeing the title, overwhelmed Wales 42-0 while Scotland defeated Fiji 29-15 in a gripping second contest in the Manchester doubleheader.
England's huge scoreline eclipsed their previous biggest World Cup win, 84-19 against Fiji in 2022.
The scoreline was no surprise. England won a 29th straight Test. None of the Samoans have played 29 Tests. They're at their first World Cup in 11 years.
England made 13 changes after beating the United States 69-7 in the opening game and lost nothing in flow or strength or ambition.
The Red Roses scored 14 tries, bringing up the bonus-point fourth in the 16th minute. Flyhalf Helena Rowland converted 11, including for her own try from the sideline. Her 27-point haul was a game record for England in World Cups.
A week after their previous heaviest World Cup loss by 73-0 to Australia, the Samoans felt far from embarrassed at Franklin's Gardens on Saturday and celebrated their first points of the tournament, a penalty by flyhalf Harmony Vatau.
Canada's tight five were exceptional in their big win and sent every Wales scrum in reverse.
They also stormed around Salford Community Stadium, a big reason Canada could reel off long phase plays and a 15-metre rolling maul try.
Prop McKinley Hunt scored two tries, her replacement Brittany Kassil one, and lock Sophie de Goede was the player of the match with 20 carries, 10 tackles and six-for-six off the tee.
Wales responded to being embarrassed by Scotland last weekend but pride couldn't overcome power.
Scotland deserved their win in the rain but were pushed the entire way by Fiji, who will wonder how much closer the result might have been if they had kept 15 players on the field.
Fiji played more than 30 minutes with 14 women after a red and two yellow cards. And, yet, every time the Fijians looked down and out they hit back.
Fiji had a bad start; 18-year-old wing Michella'e Stolz left injured and prop Vika Matarugu was yellow-carded for a high tackle. But prop Loraina Senivutu scored after a big run by flanker Nunia Daunimoala.
Fiji started the second half much better. Adi Salote Nailolo, Alowesi Nakoci and Daunimoala ripped apart Scotland and No. 8 Manuqalo Komaitai crashed over.
Francesca McGhie's second try gave Scotland a four-try bonus point and, in a double blow to Fiji, Tawake's tackle on counterpart Elis Martin was deemed too high. Her yellow card was upgraded to a 20-minute red.
Scotland standout Orr then put them out of sight at 29-10 by beating three forwards en route to the try-line.
Just the third draw in World Cup history kept the US Eagles' playoff hopes alive and could cost the Wallaroos.
Australia would have advanced with a win but must now topple England, or at least lose narrowly. By the time the Wallaroos face England next weekend, they will know exactly what's required.
The Americans will have already played Samoa, the much easier assignment. The Eagles should beat Samoa and then the race with Australia will likely come down to points difference.
