Up to 200! But when A/V is on, you can have twenty-five (25) people join you in a Rabbit room at the same time.
Rooms that exceed twenty-five (25) people are called party rooms.
What does it mean to have a party room?
Web and Mobile
A party room is when there are more than 25 people in one room at the same time. The maximum amount of people for a party room is 200 (including the room owner/host).
In rooms of this size, A/V will automatically be disabled in an effort to make the room all about the Rabbitcast. A banner notification will appear in the Rabbitcast, notifying everyone who is currently in the room that A/V will be disabled.
Once a room has more than 25 viewers, the ability to Pin Everyone will also be disabled.
