All four group winners progressed, with home victories for Milton Keynes, Hemel Storm, Reading Rockets and defending champs Derby Trailblazers.
The competition is organised by NBL1 Men's clubs in partnership with naming rights holder Kitking.co.uk and Basketball England.
We take a look back at all four quarter-final games below, with the semi-final draw set to take place later this week.
Milton Keynes eased into the next round with a comfortable 27 point victory over last season's finalists Bradford Dragons.
A 22-20 opening quarter gave both teams a shot in this one, but the hosts took the second frame to lead 47-35 at the main change, further extending their advantage in the second half.
MK shot an impressive 56% from the floor, and won the rebounding battle 47-25, to sweep aside the Dragons, who struggled down low and conceded 56 points in the paint.
That led to a productive afternoon for Adrian Scarborough (16pts, 10reb, 7/7FG), KJ Johnson (20pts, 7ast) and Nate Robinson (20pts), whilst returning forward Chris Tawiah (12pts, 6reb, 6/8FG) eased back into life with the Breakers across 13:51 of action.
Bradford managed to pull their deficit back to 14 points early in the final quarter, but their opponents would pull away for good shortly after. Jevon Laidler (16pts) led all scorers for the visitors, with Micah Savery-Richards adding 12 points and six boards from the two-man Bradford bench.
Hemel booked their place in the last four with a 95-82 victory over Loughborough Riders.
A four point ball game going into the last 10 minutes, this one was up for grabs throughout before the hosts peeled off a 22-13 final quarter to take the W.
Like the Breakers, Hemel were also able to win the key battles around the basket, out rebounding the Riders 46-40 and piling up 54 points in the paint.
Standout guard Sam Newman enjoyed a quality outing, putting together a 13 point, 10 rebound, 14 assists triple-double around key performances from Trent Monkman (24pts, 7reb) and Matthew Ellis (22pts, 8reb).
Loughborough were able to keep the reigning D1M playoff champs within touching distance thanks to the exploits of Victor Ndoukou, with the Riders man dropping a game-high 31 points on 50% shooting (12/24), as Edward Onyia (12pts, 12reb) added a double-double off the Loughborough bench.
Derby were pushed all the way by a dogged Solent on Saturday night, with the Trailblazers doing just enough to outlast their D2M opponents.
Solent led for most of the first quarter before finishing the opening 10 minutes tied up, allowing the hosts to then move in front. The current KitKing holders were unable to pull out of sight though, with the Kestrels keeping their opponents in check until they finally surrendered a double-digit lead late in the fourth.
All five of Solent's starters would score 14 or more, led by recent Team of the Week pick Isa Brandon, who had a 21 point, 15 rebound double-double alongside Russell Gariepy's 21 points and eight assists.
Solent's team approach couldn't overcome DTB's heavy hitters though, with Leighton Elliot-Sewell (32pts, 9reb) and Malcolm Smith (32pts, 4reb, 4ast) both putting up huge stat lines to edge their team into the semi-finals.
A standout performance from guard Mitch Clarke saw Reading past Thames Valley Cavaliers in yesterday's only game.
Clarke was on fire, dropping 29 points that included 6/8 from beyond the arc, adding eight assists and four boards to a solid afternoon's work.
Victor Olarerin (21pts, 6reb) added to Reading's damage from the guard spot, providing a one-two punch that TVC couldn't overcome.
The Cavs certainly had their moments, leading 26-19 after the first quarter and levelling the scorers at 48-48 early in the second half. A rapid 15-2 run would break the game open for the hosts shortly after though, giving the visitors too much to do the rest of the way.
Justin Robinson (29pts, 5reb) was in great form for the Cavs, with Ed Lucas (20pts) and AJ Roberts (17pts, 8reb, 4ast) providing the support.
