# CreatePlayerSessions
<a name="API_CreatePlayerSessions"></a>

 **This API works with the following fleet types:** EC2, Anywhere, Container

Reserves open slots in a game session for a group of players. New player sessions can be created in any game session with an open slot that is in `ACTIVE` status and has a player creation policy of `ACCEPT_ALL`. To add a single player to a game session, use [CreatePlayerSession](https://docs.aws.amazon.com/gamelift/latest/apireference/API_CreatePlayerSession.html) 

To create player sessions, specify a game session ID and a list of player IDs. Optionally, provide a set of player data for each player ID. 

If successful, a slot is reserved in the game session for each player, and new `PlayerSession` objects are returned with player session IDs. Each player references their player session ID when sending a connection request to the game session, and the game server can use it to validate the player reservation with the Amazon GameLift Servers service. Player sessions cannot be updated.

The maximum number of players per game session is 200. It is not adjustable.
