Midnight Madness 2025

Does your team have the IQ and competitiveness needed to win any intellectual challenge? Do you know a group that relishes out-witting the puzzle-makers? When it comes to completing treasure hunts that no-one else can do, are you the person standing on the X that marks the spot?

If so, join us as the most ambitious immersive challenge ever created takes to the streets of London once more.

The Event

Using the city’s most iconic landmarks and prestigious buildings as its stage, Midnight Madness sees teams of players from the UK and abroad battle it out in a spectacular display of mind power and stamina, in an effort to be crowned Midnight Madness champions 2025.

Taking place throughout the night and curated by the world’s leading puzzlers, the evil geniuses of Game Control challenge the teams in a Crystal Maze-meets-Da Vinci Code treasure hunt within the City of London.

It is the experience of a lifetime, putting intellects to the test, whilst fundraising for small children’s charities across the UK.

“[It’s not traditional fundraising] you’re not just behind a desk; you’re not running some marathon course that everybody else is running; you’re not just sitting at a high society dinner; you’re out in the world being an intellectual athlete.”
