About #42

High Five!

A complete quiz experience

42. Douglas Adams fans already know it: this number is the answer to all questions. Who else has the answer to all questions? We do. Our team of enthusiastic event managers and quiz makers, led by Number 42 founder  Julinka van Keulen, check over 15,000 answer sheets every year.

Number 42 offers you a complete pub quiz, one that deviates from the norm. We do not only create quiz questions and assignments. We sit down with you and pick our brains together. What do you want to achieve with your quiz?

Is it meant to supplement a congress, seminar, or conference? Do you want to give your employees a chance to get to know each other? Or is it simply a cool online teambuilding quiz for your organisation?

Whether it’s about getting to know colleagues, arousing enthusiasm for new policies, or simply a knowledge quiz for a team activity: we will dive deep into your profession, dig through the company history and conjure up a custom game concept. Gamification with a serious underlying message.

Unique quiz concepts

From creative concept to execution. With us, your quiz event is in good hands. Number 42 was founded in 2010 by joined forces: graphic design, event organisation and a passion for quizzes. The latter quickly took over, and by now we organise over 100 quizzes each year. Always custom made, based on our clients’ demands. What we’re good at? Quizzes for large groups. Our Quiz Night XL sees no fewer than 1,400 participants. However, we never forgot our roots, and that is exactly what makes our concept so unique. What do you have in mind?

I'm curious about your quizzes!


For Eindhoven, my passion

Groningen, Maastricht, Middelburg, Amsterdam: we definitely get around. Eindhoven, however, is our base of operations, and the place where we create all our pub quizzes and game concepts. Because we lost our hearts to this city, we want to give something back, too. Our largest knowledge quiz – which is named Quiz Night XL (what else?) and has science & technology at its roots – takes place in the Klokgebouw each year. We are also inextricably connected to the Eindhoven International Quiz Night, where we bring together Eindhoven expats for a great time with the most challenging quiz questions.

The right face for your pub quiz

Jeopardy has Alex Trebek. Eggheads has Jeremy Vine. And what Jeremy Paxman is for University Challenge, Julinka is for Number 42. She is the face of our knowledge quizzes and our pub quizzes for international groups. With her immaculate – near-native – English pronunciation, Julinka expertly takes our participants from question to question. We also work with various experienced freelancers who are perfect for the role of quiz master. With their expansive experience, they have been reinforcing the #42 team for years.
