How to use Minecraft seeds
Using a Minecraft world seed is very easy to do for a single or multiplayer game.
To use a world seed for a single player game of Minecraft simply select single player from the main menu, and go to create new world. Go to more world options, and in the black box paste my seed in there, or try using your own and submit your seed to us! You can also leave this blank, and the game will generate a random seed for you. Select done, and create the world. You are now playing in the Minecraft world seed you selected.
