World 1-Fortress

World 1- is the fortress level of Grass Land in Super Mario Bros. 3, let alone the first one overall. The player is given a time limit of 300 seconds to complete it.
== Layout ==
As the first fortress level of the game, this level is relatively simple. Obstacles such as Roto-Discs and Podoboos are introduced, as well as Dry Bones.
The player must jump across multiple gaps, while avoiding the Podoboos that continuously rise up and down between them. A ? Block containing a Fire Flower may be found here. After more gaps, there are a few sets of Roto-discs that the player must get through, followed by more gaps. At the end of the section, a door leading to the next part of the level may be found. Another ? Block, this time containing a Super Leaf, is also found here, along with a single Dry Bones Beyond the door is a hallway with a spiked ceiling. The ceiling slowly rises up and down, meaning the player must duck in order to avoid taking damage from the spikes. At the end of the section is another door, which rises up and down from the ground with the ceiling. Beyond this door is Boom Boom's arena; defeating Boom Boom will destroy the fortress, unlock the gate near World 1-1, and allow the player to continue onto World 1-5.

==Trivia ==
*In the Japanese version, the ceiling with spikes has four more spikes on the right. Those four spikes were removed in the North American version to make it easier.
