The competition had eight groups of six, with the players only needing to finish in the top four to progress - but there were still high-profile casualties.
Ebdon won two of his five matches but missed out in a group that was won by Mark Williams and that also saw Aditya Mehta, Thanawat Thirapongpaiboon and Ken Doherty qualify from it.
Maguire, the fourth seed, could only win one match in his group despite being the highest-ranked player, while Wuxi Classic semi-finalist Campbell endured a similar fate, including a 5-2 defeat to the man who beat him in China last week – Ricky Walden.
Ninth seed Gould finished on the same amount of points as Graeme Dott and amateur Panompai Powises in his group but went out on frame difference.
Top seed and defending champion Mark Selby was the outstanding player of the round-robin stage, winning all five of his matches and losing just seven frames in the process.
He faces Doherty in one of the most attractive-looking last-32 ties.
