When last I wrote about Dishonored 2 I lamented how tough it is to play a game like this as a time-strapped parent, what with all the secrets buried in levels that feel designed to be played in one long sitting. I’ve now finished the game and am thrilled with a moment that made it great to play as a husband.

Dishonored 2 became an unexpected marriage highlight thanks to a terrific logic puzzle that appears late in Arkane Studios’ 2016 stealth adventure. The puzzle is the core part of a complex door lock that opens once you match five names with five objects. Those names and objects are mentioned, along with five colors, five cities and five drinks, in a written clue near the lock. The lock is located early in one of Dishonored 2’s final levels. You can leave it alone and creep through other parts of the level looking for clues that make opening it easier, but it’s more challenging, cooler and will get you a Trophy or Achievement if you solve it right there without added help. That’s how I chose to solve it.

Our own Kirk Hamilton raved about the puzzle in 2016, though he also embarrassed himself by showing his chicken-scratch way of solving the thing.

Here’s Kirk in late 2016:

And here’s how you really should do it:

In 2016, Kirk explained that the puzzle was randomized. My version of the clues were different than his, but as soon as I saw how the puzzle was written, I recognized what kind of puzzle it was. It was a logic puzzle comprising a series of sentences that gave you just enough information to reason out which of five people hailed from which of five cities, were drinking which of five drinks, were wearing which of five colors, and were sitting in which order while holding which of five old objects.

I snapped a photo of my version of the puzzle to use as reference on my phone and then began constructing the kind of grid I’d seen in the puzzle books I’d gleefully filled out as a kid.

I hadn’t solved a logic puzzle in decades, but this stuff sticks with you. What I’d never done, I soon realized, was make the grid used for solving these puzzles. I made my rows. I made my columns. You don’t want the elements in the row and the column to intersect more than once. I kept sketching tables that did just that.
