Around our house, we love a good puzzle. It’s part of the furniture — brain-teasers at the table, riddles in the car, a general suspicion that anything can be turned into a game if you look at it right. So when my son’s eighteenth birthday came around and he told me what he wanted, it wasn’t just a party. He wanted a murder mystery — a night where he and his friends could sit down together and solve something.
That’s a brief. A real one. A specific thing, for a specific group, on a specific night. And a brief like that is the best gift a person can hand you if you like to make things, because it tells you exactly what you’re solving for.
So I built the night. Nine puzzles in all — seven scattered around the house for the teams to move through and work out together, then two more that funneled everyone down into the final whodunit. Dinner first, then about an hour of teasers, then the Clue-style reveal at the end. And here’s the thing I had to keep reminding myself the whole time I was designing it: it did not matter one bit what I found fun.
I’m older than eighteen. I like a hard puzzle, the kind you chew on for a day. If I’d built the night I’d want, I’d have built it for me, and it would have died on the table in front of a room of teenagers. So I set that version of me aside and built for them — for what my son loves, the history and the Professor Layton brain-teasers and the wordplay he’s been doing for years, and for his friends, who are cut from the same cloth. The question was never “can I solve this?” It was “can they?”
And that turned out to be a harder question than I expected, because I got the answer wrong in the most interesting way.
I wrote a cipher — a letter-shift, where you slide each letter back three spaces to read the hidden word. I thought it would be a good challenge. My son cracked it in about five seconds. Then I wrote what I thought was a gentle riddle, a little play on making a toast, the kind of thing I figured they’d get instantly. It stopped them cold. Clue after clue, and they still had to fight for it.
I’ve thought about that flip a lot since. It wasn’t random. These are kids who grew up pattern-matching at speed — puzzles, games, screens, systems with rules to crack. The mechanical cipher was their native language; they saw the pattern before I finished explaining it. But the slow, lateral riddle — the one where you have to read every single word and sit with what it actually means — that’s a different muscle, and it’s the one they flex the least. Without meaning to, I’d run a little experiment on how this generation thinks, and it inverted everything I assumed.
Which brings me to the thing I actually want to say, because there’s a trap on both sides of designing for other people.
I could have handed them something easy. They’d asked for a fun night, and it would have been simple to give them puzzles a child could solve and call it a crowd-pleaser. But that’s not respect — that’s pandering, and pandering gives people less than they’re capable of. The other trap is the opposite one, and it’s the one people like me fall into: build it high and hard and clever, the way I’d want it, and let them feel the reach of my own cleverness. That gives them less too. It just dresses the withholding up as sophistication.
The whole job was to aim at neither. To build for the top of what they could actually rise to — hard enough to be worth solving, fair enough that solving it felt earned. Respecting people’s capacity means calibrating to it, not performing above it and not stooping below it.
I didn’t get every puzzle right. But I built in enough variety that when my calibration was off, there was still something on the other side that landed. By the end of the night they’d worked their way down to the killer, and it had taken them the full hour, and it was satisfying in the way only a thing you had to work for is satisfying.
A couple of the kids told me I needed to throw another one soon. That made me smile — you make something, and it lands, and that feels good.
But that wasn’t the best part. The best part was my son, at the end of his party, having had a genuinely good night with his friends in our home. That was the whole brief. Everything else was just me trying to be worthy of it.
