CONFIDENTIAL / CASE BRIEFING
The story starts here.
Think you know your city's streets? Think again. You're being watched, and it just got very personal. Your sister is gone, and a sadistic mastermind named "Razor" is holding the blade.
You’re not just taking a walk; you’re a pawn in a twisted scavenger hunt where the stakes are life and death. To find her, you’ll have to save others first—strangers trapped in Razor’s deadly games. You’ll need to solve sinister puzzles and help a detective trace the killer's location.
The clock is ticking, and every wrong move brings your sister one step closer to her final cut. Do you have the nerves to outsmart a killer, or will you become just another notch on his blade?
Is this for you?
Who it's for
This London edition sends you along a 2 km route through the city's streets in around 90 minutes, solving sinister puzzles to rescue strangers from a killer called Razor and track down your missing sister. Adults who love horror and thrillers, friends after a dark night out, and escape-room regulars wanting an outdoor game will enjoy it. Anyone uneasy with a serial-killer story should pick a lighter quest.
What makes this quest special
Highlights
A sadistic killer has people trapped around London and has given you the only clock that matters.
Crack story-driven puzzles under pressure, each one a setup you have to undo before the person inside it runs out of time.
A route of 2 km from Garrick St, running past Trafalgar Square, Nelson's Column, and St Martin-in-the-Fields, turns streets you thought you knew into a crime scene.
For horror and thriller fans, best with a friend who keeps their head, and not the gentlest way to spend an evening.
Just your phone, playable after dark for the full effect, and you decide when the next victim gets your attention.

Frequently asked questions
What kind of crime game is this?
It is a self-guided thriller walk played on your phone. Your sister has been taken by a killer called Razor, and to reach her you must first save strangers trapped in his deadly games, solving sinister puzzles and helping a detective trace his location.
Can we play it as a team or group?
Yes. There is no guide and no other group to join, so your own friends, colleagues or partner play together, sharing the puzzles as you walk. One ticket covers your whole group, which makes it an easy option for a small team outing.
How long does it take and how far do we walk?
Plan for around 90 minutes and about 2 km on foot through the city. You can pause the game at any point and continue later, so a break for food or drinks does not mean losing your progress.
Is it suitable for children?
It sits in the horror category and the story centres on a sadistic serial killer, kidnapped victims and life-or-death puzzles. It is written with adults in mind, so it is not a good fit for young children, and parents of teenagers should judge the dark theme for themselves.
Do we need to book a time slot?
No. You start whenever you like, with no fixed tour time and no guide to meet, so it works well if you are deciding on the spot what to do tonight. The game runs outdoors, so dress for the weather.
What is 20 Cuts in London about?
Your sister has been abducted by a fictional killer called Razor. You follow an outdoor rescue story around Trafalgar Square, helping trapped strangers and working with a detective to locate him.
Is 20 Cuts based on a real London crime?
No. Razor, the abduction and the deadly games are fictional thriller elements created for this quest.
Where does 20 Cuts start and finish?
It starts at Nelson’s Column and finishes nearby in Trafalgar Square. The currently listed route is approximately 2 km.

A darker fictional rescue game for thriller fans
Choose 20 Cuts for a high-stakes fictional serial-killer story rather than historical sightseeing. Its abduction and threat themes make it a darker experience than the family and landmark quests elsewhere in London. Playable languages: English.
