Iron Door is a pure puzzle map by yeroc424. It rewards 7 FFA Points upon completion.



Iron Door consists of 6 puzzle levels, the first 5 of which have several different puzzles players could be sent to (destination is random). There are no checkpoints between each level, and almost all of the puzzles can be failed, and upon doing so, the player will get softlocked and must /kill to restart.


This map's looks vary greatly across the many different puzzles.


Original article written by yeroc424

After renovating Frosty City (formerly Cobble City), pieceofcheese87 and yeroc424 decided to work on a map together. Their ideas revolved around using fire, water, and other elements to make some sort of puzzle-maze-parkour hybrid. However, both builders ran out of ideas and motivation, and the project was dropped for a time. Yeroc wanted to make a pure puzzle map, so that pure thought could solve the map as opposed to guessing in mazes and needing skill for parkour. Also, the map would be one where the challenge could be randomized, so that it would be much harder to walk someone else through beating the map. After coming up with a few uses for the elements to make a puzzle, he determined this alone would not be enough to make a map. He enrolled the help of Neo3dc, kenad, and others to help develop a series of mini-puzzles, united by the goal of reaching the Iron Door at the end.

The map must be beaten by beating six semi-random puzzles in a row. Upon clicking an Iron Door, the player is warped to a random map with the level being one higher than the previous puzzle for the first five maps. The sixth level is always the same. Most puzzles have different versions that vary in level, so it is possible to play the same types of puzzles more than once over the course of one life.

The puzzles currently in rotation are the following:

Amazing Insight[edit]

Given a coded map of the level, safely descend all the way to the bottom floor.

Bench Press[edit]

Given an initial board of iron blocks, push them around with pistons to open a doorway.

Cartesian Coordination[edit]

Ride a cart through various clichéd sayings and choose the correct one.


Recreate a Rock Paper Scissors loop by using at least five elements to build up the walls.


Find the only bird that is not being looked at by any other bird. This features Flamango, yeroc's easter egg character.

Rock Solid[edit]

Create the names of rock bands and songs by using Minecraft blocks to fill in the blanks.

Roll With It[edit]

Traverse a single cubical room by moving walls to the floor to orient the iron door.

Su Door Ku[edit]

Solve a 4*4 color-based Sudoku board using only four initial clues.

The map allows more puzzles to be cycled in as they are made. Magna Carta, a puzzle that was planned to go in early on, was not completed, and Flamingle was created to fill the void. The map is worth 3 points and is given a yellow wool in the FFA+ Puzzle room.


This map is currently being used in Hardcore 10.1, so it isn't featured in any challenges.

Technical Info[edit]

Iron Door has its own namespace: y4id. It holds five Rtp variables:

  • rtp1 (4 warps)
  • rtp2 (5 warps)
  • rtp3 (3 warps)
  • rtp4 (3 warps)
  • rtp5 (3 warps)

The map has been ported from the obsolete /rtp plugin to the MSC Rtp equivalent. However, the prior /rtp structures still exist. These are titled y4IRON1, y4IRON2, y4IRON3, y4IRON4, and y4IRON5, and function exactly the same as the newer MSC Rtps.


  • Not all the various mini-puzzles existed upon the map's first release. Su Door Ku is an example of one such puzzle. A sign at the end of the map alludes to this fact.
  • The map is loosely based on the premise of the Hoshi Saga series of Flash webgames.
