Party Line Phone

Party Line Phone is an entertainment building in Oxygen Not Included that lets a Duplicant make a call and spend time chatting on the line. Its flavor text emphasizes the social uncertainty of the activity: you never know who will answer on the other end.

Using a Party Line Phone takes 40 seconds total. A Duplicant first spends 15 seconds dialing, then 25 seconds talking. It also has priority 5, placing it among the highest-priority recreation buildings, so Duplicants will prefer it over lower-priority entertainment options when multiple choices are available.

Because of that high priority, the Party Line Phone is useful when you want Duplicants to reliably choose a specific recreational activity rather than drifting toward less important amusements. Its fixed time cost also makes it easy to plan around in schedules and room design. If a Duplicant has access to several entertainment options, this building is one of the ones they are most likely to use first.

The phone is a simple recreational setup rather than a productivity building, so its main value is morale support and giving Duplicants an additional entertainment choice. It fits naturally into a recreation area alongside other morale-boosting buildings, especially when you want a high-priority option available for downtime.
