If you want to be able to play with your friends, you can create a group.
This option is completely free and available to everyone!!!
A group can be a space to exchange messages, to have an internal ranking, to send and receive ingredients for the Magic Workshop... In short, you can have an improved game experience! :-)
Due to the internal ranking you can compare your zoo to the zoos of other members of your group. This is a really practical and full of fun option.
