"Minecraft" is a single- and multiplayer creation game that lets you use in-game resources to build houses, weapons and other various contraptions. Ambitious players may take games online, where they build on the same map as several other players. If you are an operator, or "op," on a server, you are allowed to use numerous commands at your will. These commands perform a variety of functions, such as spawning blocks and kicking unruly players.
Have the administrator or another operator promote you to op status.

Type the slash ( / ) key, followed by the command you wish to enter. For example, type "save-all" to save the level, or type "tp player1 player2" to transport players, where "player1" is the person you want to transport to "player2."
Press the "Enter" key to activate the command.
