 The minus world is basically just a random location of the game ROM, it is not a real world. It wasn't designed that way ― it's just an oversight of the programmers that you can get into the pipe before the correct warp labels are assigned. <br>
-In the NES version of Super Mario Bros., the "minus world" was a looping, uncompleteable copy of world 2-2. In the FDS version, however, it is an underwater 1-3, 2-3, and an underground 4-4, making it completable. <br>Completing the game this way would give the "in another castle" message, but would return to the title screen as if 8-4 had been beaten; hard mode and the level selection become accessible, as well.<br>

-The random number generation in this game is purely frame-based. If you reach an enemy at the same frame from reset, it will behave the same. Due to the 21 frame rule (which also applies to the title screen), it is possible to know what frame rule you are on.<br>

 It is possible to stand on the edge of a pipe even when a plant has risen out of it. There are a few pixels of room on both sides of the pipe that you can land on and immediately jump off again. <br>

-When a lot of hammers are on the screen, you can sometimes go through a hammer without getting hit, and sometimes you can completely miss a hammer and still get hit. <br>

 You don't need to hit the top of an enemy to kill it. As long as you're moving downward as you hit the enemy, you'll kill it. <br>

 • Acceleration in water is the same on the ground as in the water, but the maximum walking speed underwater is 2/3 of the maximum swimming speed.<br>
 • If you touch underwater ground while holding right, you will be immediately reduced to maximum walking speed. If you need to only briefly touch the ground, don't hold right and start holding right just after you press A to leave the ground again. Of course longer stays on the ground will reduce you to below maximum walking speed, so hold right in these cases to stay at maximum walking speed.<br>

 • When you need to reverse direction and get below the platform, you are standing on, (for example when getting to the warp pipes in 4-2), you can reverse some of your speed by bumping into a wall and holding the opposite direction. If the gap between the platform, you want to fall off and the wall is less than 3 blocks, it's faster to do so than to just reverse at the edge of the platform.
