Return to Mysterious Island Hints

Another puzzle!

  • 1 of 28: This one's not going to be as easy as the one on the robot on the beach.
  • 2 of 28: It's going to require specific information from somewhere else on the island.
  • 3 of 28: Might Captain Nemo have written down something that will help with this code somewhere?
  • 4 of 28: If you have not yet done so, go back to the Captain's worktable in Granite House.
  • 5 of 28: Originally, there was a torn piece of paper lying on the table.
  • 6 of 28: But now -- somehow -- the paper has been restored.
  • 7 of 28: Read the note from the Captain.
  • 8 of 28: The bulk of the note provides more detail on the Captain's desire for his burial, information on the shield he used to protect the island, and the fact that Mina will need to overcome the guardian robots and board the Nautilus to disengage the shield (and leave the island).
  • 9 of 28: But the last part of the note also includes a clue to the panel aboard the Nautilus.
  • 10 of 28: At the very end of the note, the Captain has provided information about destroying the robots.  He ends with a simple arithmetic equation -- 5401 + 1860 = 6261 -- and says that it is the Nautilus panel code.
  • 11 of 28: But if you try any of those numbers on the panel, it won't respond.
  • 12 of 28: So what might he have been trying to indicate?
  • 13 of 28: Do any of the numbers look familiar?
  • 14 of 28: Particularly as they apply either to the Nautilus, or to the panel itself?
  • 15 of 28: What can you see at the top of the panel?
  • 16 of 28: There is a date -- the same date as on the hull of the ship, and above the door to Granite House.
  • 17 of 28: The date is 1860 -- which is also part of the equation left by the Captain.
  • 18 of 28: So perhaps the three numbers he left in the equation weren't exact, but only meant as a "hint".
  • 19 of 28: Where else can we find a 4-digit number relating to the panel?
  • 20 of 28: How about the number above the keys on the panel?
  • 21 of 28: It changes each time you try another code.
  • 22 of 28: What if the Captain meant to use that number as part of the equation?
  • 23 of 28: Then, perhaps, the '1860' was the fixed part of the equation...
  • 24 of 28: ... indicating to use the 4-digit number on the panel, and add 1860 to it.
  • 25 of 28: Unfortunately, in the example he used, the Captain -- despite his obvious genius in other areas -- was apparently not quite so good at arithmetic.
  • 26 of 28: Because the equation is incorrect -- it is off by 1000.
  • 27 of 28: However, use the concept of the note (i.e., the idea of adding 1860 to the top panel number, to get the bottom number), and ignore the Captain's erroneous addition.
  • 28 of 28: Add 1860 to whatever number is shown above the keypad, and then key in the 4-digit result.  (Click on each key to enter a digit.)
