A learning game built around 7 stages

Each Escape Box contains 7 compartments built around a storyline, each representing one of the subsidiary’s areas of expertise (legal, consulting, finance and more). Split into small groups, participants simulate the acquisition of a fictional start-up, project NeoMundo, and solve puzzles linked to each function. Completing a section unlocks a summary sheet recapping that department’s priorities — learning through play while building team cohesion.

Portable kits, replicated for induction sessions

Built in a run of 10 copies, this compact kit brings together 80 employees at the same time in a session lasting 60 minutes. So organisers can run it on their own, the package includes an immersive introduction video and a debrief booklet — a great way to unite your teams, just like our ready-to-play games for large organisations.

Impact and feedback

This onboarding serious game has already introduced more than 500 employeesto the business, creating real collective momentum and making it easier for functions to work together.

This game helped us understand ENGIE GBS's different roles by putting their expertise into practice. Thank you for a great experience.

Corporate onboarding escape room: frequently asked questions

How do you tell if an HR onboarding game is serious and effective?

Effectiveness comes from the balance between learning through play and realistic business scenarios. The storylines must mirror the teams’ day-to-day reality while keeping the gameplay smooth, so participants stay motivated and the learning sticks.

Why choose gamification over a traditional training seminar?

A playful format drives active engagement and strengthens team cohesion. By replacing top-down presentations with immersive simulations, every employee takes ownership of their learning and absorbs the company culture far more quickly.
