All our prediction games have an integrated function for chatting among the players. The players can use it to send a message to the admin, the admin can send a message to individual players or to all players, and the players can also communicate with each other.
Particularly in larger prediction games or in prediction games in which the players re not familiar with each other, it makes sense to disable these functions in whole or in part. As the admin, you can deactivate the individual functions in the menu "Messages" in the admin area.
