Just like at a family dinner, you can always add an extra chair at the table… but the size of the meal stays the same. That means some might end up leaving a little hungry.
Through experience, we’ve found that this room delivers the best experience with a maximum of 5 players. Any more, and some participants may end up playing the role of spectators rather than truly taking part.
That said, we occasionally make exceptions for this adventure and allow up to 6 players, especially when the group includes newcomers or those less familiar with escape rooms.
Ultimately, this limit is in place to preserve the quality of the experience for everyone.
