In the Ultimate Nightmare, you become a lead detective hunting the world's most notorious serial killer. Will you survive or become another victim?

It's back to school for you. Will you graduate or be expelled?

You've been accused of a crime you did not commit and now you've been sentenced to death. Will you give up or escape the room to prove your innocence?
Most escape rooms are limited to 4–6 players, so finding one for a large group is a classic organizer's headache. This page features rooms in Waterville that can actually accommodate 7, 8, and even 10+ people: large multi-room sets, duel formats where two teams compete, and venues that run multiple rooms simultaneously.
For corporate events and birthdays, call the venue after booking: many offer party rooms, championship formats across multiple escape rooms, and group discounts that aren't even listed on the site.
Practical tip: in a large team, appoint a "captain" to gather findings and keep track of time — with 8 pairs of hands, the bottleneck isn't the complexity of puzzles, but communication. Duel rooms solve this by splitting you into rival teams.
