# Group event types

A **group** event type lets *several invitees book the same time slot* — one session,
many attendees. Use it for webinars, training sessions, office hours, or any meeting
where more than one person joins at once.

It comes in two flavors, both chosen from the **Type** dropdown in the event-type
editor:

- **Group** — you (one host) run the session, and many invitees book the same slot.
- **Group + Round Robin** — the same group session, but hosting **rotates across a
  team** so duties are shared. (This is the type announced in the
  [June 1 changelog](/news/changelog).)

## What it is

Unlike a [one-on-one](/help/event-types/one-on-one) or
[round-robin](/help/event-types/round-robin) — where booking a slot *removes* it — a
group slot stays open until it fills:

- You set a **Max invitees per slot** (anywhere from 2 to 9,999; it defaults to 10).
- The slot keeps accepting bookings until that many people have signed up, then it
  disappears from the booking page.
- Each invitee books individually and gets their own confirmation; they all share the
  one meeting.
- Optionally turn on **Show remaining spots to invitees** so the booking page displays
  how many seats are left.

### Group (owner-hosted)

A plain group event has a single host — you. The booking page shows *your*
availability (your schedule, minus your calendar's busy events and buffers), and you
host every session. The link is `42min.us/<your-username>/<event-slug>`.

### Group + Round Robin

Attach a group event to a **team** and it becomes a **Group + Round Robin**: the group
session is still capped at Max invitees, but the *host rotates across the team*. It
merges round-robin host-sharing with group seating:

- The booking page shows the **union** of every active team member's availability —
  each on their own schedule — so a slot appears if *any* member is free for it, just
  like a [round-robin](/help/event-types/round-robin).
- Seats work exactly like a plain group event: the slot stays open until Max invitees
  fill it.
- **The host is assigned per slot, at booking time, and then locked.** When the first
  invitee books a given slot, 42min picks an available team member (the one with the
  fewest recent meetings, the same fair distribution a round-robin uses), and *every*
  later invitee who books that same slot meets that same host. Different slots can go
  to different hosts.

If your team uses **Balance** mode, members who are three or more bookings ahead of
the team minimum are skipped until the others catch up — see
[Teams](/help/team-and-admin/teams) for that setting.

Like a round-robin, a Group + Round Robin event is shared at the team level, e.g.
`42min.us/team/<team-slug>/<event-slug>`.

## How to set one up

1. For a **Group + Round Robin**, first make sure the **team** exists
   ([Admin Center → Teams](/360/teams)) with the right members. A plain **Group**
   needs no team.
2. Open [**Event Types → New Event Type**](/360/events?new=1) and set **Type** to
   **Group** or **Group + Round Robin**.
3. For Group + Round Robin, pick the team from the **Team** dropdown that appears.
4. Set **Max invitees per slot**, and tick **Show remaining spots to invitees** if you
   want the seat count visible on the booking page.
5. Fill in the **name**, **description**, **duration**, **meeting type**, and the
   [schedule](/help/getting-started/setting-your-availability) — the rest of the editor
   works [just like a one-on-one](/help/event-types/one-on-one#the-event-type-editor).
6. Save.

## Group meetings and Zoom

When a group event uses **Zoom** as its meeting type, 42min creates a **Zoom Webinar**
rather than a regular meeting, so a large audience can attend cleanly. See
[Zoom](/help/integrations/zoom) for the details and prerequisites.

## Common pitfalls

- **Picking Group when you meant Round Robin.** A plain Group lets *many people share
  one slot*. If you instead want one link where a team shares the bookings but each
  slot is a private 1:1, use a [round-robin](/help/event-types/round-robin).
- **No team yet.** Group + Round Robin needs a team — set up the
  [team and its members](/360/teams) first. (A plain Group doesn't.)
- **Expecting each invitee to get a different host.** Within a single slot the host is
  fixed once the first person books — everyone in that session meets the same host.
- **Max invitees set too low.** The slot vanishes the moment it fills; raise the cap if
  sessions are filling before everyone you expected can book.
