# Configure Rooms
From the left sidebar, select **Rooms**. On this page you can:
* Choose the regions you want to allow your rooms to be created in.
* Enable Simulators for your Rooms.
* View a list of recently created Rooms.
* View a list of recently uploaded Simulators.
### Simulators
From the Online Dashboard, you can configure what size you want your [Simulator](/manual/simulation-server.md) instances to be. To attach a Simulator to a Room, send the ["Simulator slug"](/manual/simulation-server/simulator-slugs.md) uploaded through the SDK with the Rooms creation request. When using the [Unity Cloud Service API](/hosting/coherence-cloud/coherence-cloud-apis.md) to create Rooms, the Simulator uploaded through the SDK is automatically assigned in the creation request.
### Replication Server & Send Frequency
The packet frequencies for sending and receiving data can be adjusted per project. It is part of the **Advanced Config** section and adjusting the frequencies is available only for paid plans.
### Recent Rooms Table
The **Recent Rooms Table** provides a quick view of the recently created Rooms with the following information per column:
| Column name | Description |
| -------------- | ------------------------------------------------------------------------------------------ |
| **ID** | ID of the Room. |
| **KV/Tags** | Key-value pairs associated with the Room, followed by Tags attached to the Room. |
| **SDK/Schema** | SDK version used by the Room, followed by the Schema ID used by the Room. |
| **Logs** | Allows viewing Room logs and Replication Server (RS) logs. |
| **IP** | IP address of the Replication Server attached to the Room, followed by a region indicator. |
| **Status** | Open / Closed, how many active players and when it was created |
| **Sim Status** | Status of the Simulator attached to the Room (Starting, Started, Stopped). |
| **Sim** | Simulator Slug for the Room (if using Simulators) |
### Creating, Fetching and Joining Rooms in Unity
Please refer to the [Cloud Service API: Rooms](/hosting/coherence-cloud/coherence-cloud-apis/rooms.md) section.
### Closing Rooms
Rooms are automatically closed within a few minutes after the last player has left the room. This can be changed in the **Advanced Config** section.
### Current Limits
**Players**
The default setting is 10 players hosted, but you can specify your own value anywhere **between 2 and 100 players**.
To support more than a 100 players per room, write to ****
**Entities**
**1000 by default**, but can be increased up to 65535 in local development or client-hosted scenarios.
There is no UI button for increasing the supported player count, so you need to work through our [Rooms API](/hosting/coherence-cloud/coherence-cloud-apis/rooms.md).
When creating a room via `ReplicationServerRoomsService.CreateRoom` you can pass `SelfHostedRoomCreationOptions` as creation options.
To change the Entity limit just set the `SelfHostedRoomCreationOptions.MaxEntities` to a desired value.
**Tags**
* Each individual tag: max 50 characters.
* Total size of all tags combined: max 500 bytes.
**Key-Value Pairs**
* Each individual key: max 50 characters (min 1).
* Each individual value: max 50 characters (min 1).
* Total size of all keys + values combined: max 2,000 bytes.
