Single Player
Single Player lets players play The Blockheads on their own. Worlds created in single player are stored on the player's device and are accessible when the device is online or offline.
On iOS implementations of The Blockheads, another player can be invited over Game Center into a single-player world. A single-player world can also be hosted over local network to allow up to five other players to join the world.
If the app is deleted, all single-player worlds on the device are deleted. Items can be transferred from single-player worlds to other worlds via portal chest, although blockheads may not, and are tied to the world they were created in.
Single player worlds let you play freely without the fear of griefers or others wrecking your world( unless you use game center). It is a fun oppurtunity to see how much you can bring to a regular world to a world with many items.
