# 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 Developer Portal, you can configure what size you want your Simulator instances to be. To attach a Simulator to a Room, send the "Simulator slug" uploaded through the SDK with the Rooms creation request. When using the [PlayResolver](/0.10/coherence-api/rooms.md#rooms-api) 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 provide a quick view of the recently created Rooms with the following information per column:
| Column name | Description |
| ------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **ID** | ID of the Room. |
| **KV** | Key-value pairs associated with the Room. |
| **Tags** | Tags attached to the Room. |
| **SDK** | SDK version used by the Room. |
| **Sim** | Sim Slug for the Room. |
| **Schema** | Schema ID used by the Room. |
| **IP** | IP address of the Replication Server attached to the Room. |
| **Created** | Time duration since the Room creation. |
| **Room** **Status** | Status of the Room (Open or Closed). |
| **Sim Status** | Status of the Simulator attached to the Room (Starting, Started, Stopped). |
| **Messages** |
Messages from the Simulator orchestration. This field is usually empty but will contain a message if an issue happened with the Simulator life-cycle. The message provides the reason for the Simulator's current state (usually Stopped). Once a Simulator is stopped (for Room inactivity for instance), the Message column will mention Idle-stopped.
