In the original "Super Mario Bros." game released for the Nintendo Entertainment System (NES) in 1985, warp zones are special hidden areas that allow you to skip forward to later worlds in the game. These can be incredibly helpful in saving time and in bypassing particularly difficult levels. Here are the known warp zones and instructions on how to access them: **World 1-2 Warp Zone to Worlds 2, 3, and 4:** 1. Play through World 1-1 and advance to World 1-2. 2. About halfway through World 1-2, you will find a series of platforms with Goombas walking on them. Above these platforms are blocks that can be broken if Super Mario or Fire Mario hits them. 3. You need to break two blocks that are in the line with the pipe that doesn't have a Piranha Plant in it. This is located right after the Goomba platforms mentioned above. 4. Once you have broken these blocks, jump on top of the pipe. 5. Now that you are on top of the pipe, jump to the ceiling and move to the right. Mario will be walking on the ceiling off-screen. 6. Keep walking to the right until you reach the end. There you will drop into a small room with three pipes labeled to Worlds 2, 3, and 4. 7. Enter the desired pipe to warp to the beginning of that World. **World 4-2 Warp Zone to Worlds 2, 3, and 4:** There's actually another warp zone that can be accessed in World 4-2 which leads to the same worlds as the World 1-2 warp zone, but it is more hidden. To access it: 1. Make your way through World 4-2 until you reach a section with a moving platform. 2. Before you use the moving platform, use the blocks to hit an invisible block containing a vine. 3. Climb the vine to reach a bonus area. 4. At the end of this bonus area, you will drop down into a room with a warp zone that leads to Worlds 2, 3, and 4 as well as in World 1-2. **World 4-2 Warp Zone to World 5:** Alternatively, in World 4-2, you can find a warp zone to World 5 using a different method: 1. Continue through World 4-2 past the first set of elevators you come across. 2. Before you use the second set of elevators, you must perform a jump maneuver to reveal an invisible block. This block can be strategically used to break a hole in the ceiling without needing to jump from the elevators first. 3. Jump onto the ceiling and run to the right as in World 1-2. 4. You will enter a zone with a pipe leading directly to World 5. **World 8 Warp Zone:** Finally, the last warp zone is in World 4-2 but leads to World 8, the final World: 1. To access this warp zone, you must use the same moving platform mentioned earlier in World 4-2, but instead of hitting the invisible block for the vine, continue to the right and use the platform to reach the ceiling of the stage. 2. Run along the top of the stage (similar to the technique in World 1-2) until you reach a gap. 3. Drop down the gap while still on the ceiling, which takes you to a hidden area. 4. This area has three pipes, which will take you to World 8 if entered. Remember that warp zones effectively allow you to skip large portions of the game, which can be very gratifying, but also means missing out on some levels and the added challenge that they provide.
