Mind games will be taken to the max when it returns to Channel 5 tomorrow.
Housemates with the power will influence, twist and control the show more than ever, and fans will also be given the chance to manipulate events.
Here, TV body language expert Judi James looks back at the top 10 biggest power trippers from Big Brother and Celebrity Big Brother.
1 “Nasty” Nick Bateman
Why: The first Big Brother series was won by Craig Phillips but it was Nick who set the direction, lying about his wife being killed in a car crash and getting booted off the show for trying to manipulate housemates’ eviction nominations.
2 Victor Ebuwa
Why: Teamed up with pal Jason Cowan on BB5 to form the Jungle Cats gang and got warned about his role in the infamous Fight Night.
The arch gameplayer, who sparred with the Lipgloss Bitches, said: “I played it like a chess game.”
3 Makosi Musambasi
Why: The drama queen gave fellow housemates and viewers the runaround on BB6, covering up the Secret Garden annex plot and sensationally claiming she was pregnant after a romp in the pool with winner Anthony Hutton.
4 Ziggy Lichman
Why: The memorable hunk famously kept us guessing during his on-off relationship with Chanelle Hayes in BB8. The model even got death threats and was branded a “sly dog” by other housemates.
5 Chantelle Houghton
Why: One of the most popular housemates, Chantelle was also actually one of the biggest manipulators. She convinced the celebs she was a singer with the band Kandy Floss when she was just an ordinary member of the public.
6 Conor McIntyre
Why: Conor settled in as Luke Anderson’s wingman from the start of BB13 and when a task involved them both vying for half the prize money it looked like Conor would let Luke decide the action.
But he pressed the buzzer at the last minute and walked out clutching half the prize money, leaving his mate in tears.
7 Heidi Montag and Spencer Pratt
Why: Speidi shook up the CBB house in January 2013 by laying into other contestants, but leaving them guessing whether their bad behaviour was all an act after all.
8 Pete Burns
Why: The lippy star tried to throw his weight around in CBB4 with his acid-tongued jibes at Jodie Marsh and Traci Bingham.
He even had police chasing after him after falsely claiming his coat was gorilla fur.
9 Dexter Koh
Why: Dexter managed to get through 13 weeks of BB14 without once revealing what looked like the true side of his character, fooling housemates and viewers.
10 Jim Davidson
Why: Despite his reputation for controversy, the comedian somehow managed to take the moral high ground while still getting in plenty of barbed comments.
He ended up winning and even his arch-enemy Luisa Zissman was treating him like a father figure.

Nor me AImee 
Maybe BB7's Pete, with his perfectly deployed sob stories just before the end.
Noreen messed with the guys' minds something shocking too

Its a typo, ye cheeky pup 
I would put that Chinese playboy from last year on the list.
I would have had Nadia on that list. 
I'd have had MadCowsie at the top of that list

Oh I forgot about her !!
So basiclly the HM's Judi James didn't like then.
I'm starting to wonder was Aisleyne a player after all. She turned out to be a different person to the one I adored during BB7.
Wailing and gesticulating for paps, outside Amy's house on the day she died was a low. Plush all the trashy stuff.
Sorry I digress

That was Dexter Koh.
TBH, I agree with Vids that the list is really just of HMs that JJ didn't like. I wouldn't have put Dexter on the list: yes, he was trying to manipulate things, but he was so rubbish at it I don't think he really fooled anyone - inside or outside the house. The viewers kept him in simply because he was entertaining. Even with all his faults, he'd still have been a better winner than Sam - a HM so boring that he appeared less often in the end-of-series montage than HMs who got evicted in the first few weeks... 
Like other FMs, I also question Ziggy's inclusion on the list, and I don't think Chantelle deserves to be there either. She was taking part in a task, and she wasn't actually all that successful at it. I read an interview with Maggot in the NME afterwards, and it was pretty-much acknowledged that he and Preston put themselves behind her in the "fame" ranking as an act of chivalry more than anything-else.
A few HMs who probably should be on the list:
Pete (BB7): I've still got mixed views about him, but it's often forgot that Aisleyne completely bought into his "dream" stuff to the extent that she chose Spiral to enter the house as a "sign" for him.
Charley (BB8): Because she wasn't very popular outside the house, I think it's often forgotten how manipulative she was on the inside. It was observed afterwards that Emily probably wouldn't have been evicted for using the N-word if it hadn't been for Charley going on and on about it. First she wasn't bothered about it, then when Emily was removed it turned out she was bothered, and then it turned out that she'd been formally warned for using the word herself.
On top of that, she tried to turn the HMs against Lesley with her lies about "pee-gate", and later she tried to humiliate Chanelle in "dirty-knicker-gate". She really could be a nasty piece of work. 
Alex (BB12): Possibly the most successful HM in creating a totally false persona inside the house. As the series progressed, evidence turned up on the forums that showed her "girl next door" image was nothing like how she was in real life. Aaron was so fooled by her that he even considered walking in order to let her win...
