Contestants look to hand it to their opponents in rock, paper, scissors showdown
All hands were at the ready as athletes vied for the coveted title of UK rock, paper, scissors champion.
More than 100 people took part in the 10th games, hoping to survive seven rounds of the gruelling sport, and be crowned winner.
It all started in good spirits as competitors took to the arena in The Green Man pub in the City of London.
But as the night progressed the atmosphere became increasingly tense, with each progressing contestant believing they were in with a shot at winning.
Paul Knight, who dressed as Superman in the hope his superpowers would help him win, was knocked out in the first round.
He said: "I have dedicated a whole year of training to this, but I can't reveal my secrets. However, there was a special diet involved.
"Most British people are born competitors - everyone wants to be a winner."
The 43-year-old added that for the past eight years he had taken time out from his day job of "saving the world" to compete in the championships.
His best ever result was reaching the quarter-finals.
Ed Latham, 43, entered the competition as Darth Vader.
He said: "I came as Darth Vader because I want to instil fear in the opposition. The force is strong.
"I do this as a release."
The structural engineer was reluctant to give away too many of his secrets, but revealed his first move is always rock, while his favourite is paper.
"It's hard to say why," he explained, saying that he liked recycled paper.
Top prize was £100, a trophy and a bottle of champagne, while those coming in second and third were also in line for alcoholic rewards.
