The practice game mode is a small map set up for the player to learn more. The practice map is beneficial to beginner players, and also advanced players as it challenges all aspects of the game. There are two Item Pedestals in the map, as well as a soccer ball. As of Fall 2018, the practice room is empty with no Item Pedestals or soccer ball.
The map spawns in one bot If nobody is in the server at the time other then you. Bots are advanced players that are set to predict your next move. As of Fall 2018, bots do not spawn.
Practice maps are the best place to set up a small map with friends. If you and a couple people would like to battle each other, or experiment with the mechanics of the game, you can set up a practice map and share the link. The maximum players a private server can hold is 10 people.
In the bottom right corner of the screen, you will be able to get a link you can share with other friends, so they can play in the same room as you.
Note: if this big box gets in the way for you, there is a big "X" at the top right to get rid of it"
