16 May 2026
Midnight Madness is an overnight immersive challenge where teams put their intellect, teamwork, and stamina to the test — cracking puzzles, stepping into storylines, and racing the clock until dawn.
With London as the stage, this Crystal Maze-meets-Da Vinci Code treasure hunt pushes players to their limits — all in aid of Raise Your Hands, supporting its work with small children’s charities across the UK.
The Event
Taking place in London on 16 May 2026, Midnight Madness is unlike anything else.
Across 12 electrifying hours, teams race through the city, cracking ingenious puzzles that unlock the next hidden location. But every stop is more than just a puzzle — it’s a world of its own.
Behind each door: breathtaking sets, storylines that pull you in, and characters so comical or convincing you’ll forget where the game ends and reality begins. One moment you’re piecing together codes in a forgotten theatre, the next you’re bartering with shady underworld figures or uncovering secrets in iconic spaces across London.
This is more than solving puzzles — it’s stepping inside a story. All while battling London’s sharpest minds, testing your teamwork, stamina, and ingenuity to the limit.

The Origins
Conceived in New York by Mat Laibowitz and Elisha Wiesel, the first Midnight Madness in 2015 raised $3.1m for charity. The London chapter has proudly carried that legacy forward, building on the vision first set by the NYC team.
Raise Your Hands believes all children and young people deserve the chance to thrive, and that small charities are essential in making this happen. Yet many struggle to survive, often too small to be seen or to weather financial challenges.
Our mission is to find exceptional small charities and offer donors a better way to support them, amplifying their impact on children’s lives. By creating a carefully curated platform of 17 UK-based charities—each with a turnover under £2m and innovative approaches—we make it easy for donors to contribute with confidence, without having to pick between causes.
