There was a deafening metallic thunk as the rogue AI locked the door of the PuzzlingCorp server room, trapping the engineers inside. A countdown appeared on the computer screen... and began counting down.
"You have only a few precious minutes before I uncover the nuclear codes and destroy the world as you know it," BorgBot said, in its calm, perfectly logical voice. "Please do not attempt to resist."
"What do we do?" said one engineer, panicking. "We're going to die in here! It's too late! I never even got to finish Agents of S.H.I.E.L.D..."
"No!" said the other, already rushing to the console. "I remember the person who built this AI, before it went rogue."
"...Mick? The nerd with the bifocals?"
"Yes, them! They had an administrative password that could shut the AI down. If we can figure out the password, we can stop it just in time. But I bet they would have hidden it..."
"What do you mean?"
"I mean that it's a puzzle. Mick loved puzzles." The engineer pointed to a file on the computer desktop. "Look, there's a Nurikabe puzzle on their desktop. Maybe it means something?"
"And there's a Post-It note." The other engineer pulled it off and read it aloud. "W1, B0."
"What does that mean?" The engineer frowned. "There's another image file on the desktop next to it. It's the periodic table, but something doesn't look right..."
(You may have to click through to the large version!)
"It must all be connected," the other engineer said. "The administrative password must be hidden in there somehow. We've got to hurry before BorgBot releases the nuclear codes and takes over the world!"
