⭐⭐⭐⭐⭐ "We had 40 people, eight teams, and nobody wanted it to end. Best corporate event we've run in years."
The Corporate Christmas Party Game That Runs Itself - for 24 to 48+ Players
You're organising a corporate Christmas party for a large group. You need something that works for 30, 40, maybe 50 people - structured enough to keep everyone engaged, competitive enough to generate real energy, and simple enough that you don't need to hire an event company or spend a week preparing.
The Winter Estate Heist Large Group Edition is exactly that. A printable murder mystery escape game for 24 to 48+ players, built from the ground up for office Christmas parties, large-scale team building events, and big group celebrations. For 24 to 48 players or more (no upper limit!), that's just over €1 per person for a 60-minute structured activity - less than a coffee. No venue hire. No facilitator. No special equipment.
Just print, divide into teams, and let the game run itself.

The Scenario
Winter Estate, 24 December 1961. A diamond vanished from a locked vault during a black-tie dinner. A guest disappeared. The case was closed within a week - no arrests, no answers, no diamond.
Over sixty years later, a collection of documents has been discovered behind a wall panel in the East Gallery of the estate, together with the locked vault. Letters, ledgers, inventories, telegrams - evidence that was never examined. Your teams have been called in to reopen the case. Six puzzles. One vault code. One hour.
Only one team can crack it first and win the game.
Built for Large Groups - No Event Organiser Required
Unlike traditional murder mystery dinners or escape room hire, The Winter Estate Heist runs simultaneously across all teams with no host, no game master, and no intervention needed. Each team works through the same six puzzles independently, racing to be the first to submit the correct vault code via our dedicated online portal.
- Unlimited teams: one printed kit per team of around 6 players - scale to any group size with no upper limit
- Self-managed hints: teams access progressive clues online if they get stuck - no one needs to manage the room
- Live race format: the online code entry portal - the first team to crack the code wins
- Zero prep beyond printing: no briefing scripts, no props to source, no facilitation training required
🏆 Printable winner's certificate: crown your champions with an official certificate - perfect for team photos, bragging rights, and making the victory feel real
The Sabotage Twist
Hidden within one of the six puzzles is a Thief's Token - a small vintage key symbol. The first team to spot it unlocks a power-up: the ability to freeze a rival team for three minutes. It rewards sharp-eyed teams, adds a layer of competitive strategy, and generates exactly the kind of noise and reaction that makes an office party unforgettable.
The Six Puzzles
Six original puzzles, each with multiple elements, yielding a one or two-digit number. Together they form the six-part vault code. Teams can tackle them in any order - no linear progression, no bottlenecks, no waiting. A sophisticated mix of logic, visual deduction, code-breaking and lateral thinking, designed for adults and accessible to mixed-ability groups.
Why this makes sense for your event: with 30 players across six teams, you're looking at around €2 per person for a structured 60-minute competitive activity. Scale up to 48 players and it drops to €1.25 per person - less than a coffee. No office party budget will question that, and no event company comes close to that price.
Ideal for: Office Christmas parties, corporate team building events, company away days, staff parties, large family gatherings, and New Year's Eve celebrations for big groups.
Players: 24 to 48+ (no upper limit on the number of teams).
Duration: 45–75 minutes.
Difficulty: Intermediate - challenging for adults, accessible for mixed groups.
