Last week I wrote about Turing Machine, a deduction puzzle that fascinated me with its cardboard computer but ultimately left me a little cold with the multiplayer experience. This week I’m talking about designers Fabien Gridel and Yoann Levet’s follow-up game, Kronologic: Paris 1920. It turns out the same designers have taken some of those clever ideas and turned them into something that feels much more like a game you’d actually want to sit down and play with other people.

Kronologic is still a logical deduction game, but the premise is wrapped in a small mystery scenario. In the puzzle I played, a detective has been poisoned, and the goal is to figure out exactly when, where, and by whom the crime occurred. The structure of the mystery revolves around an opera house made up of several rooms, a handful of characters constantly moving through those rooms, and a sequence of time steps representing the evening’s events. The key piece of logic driving the puzzle is that the detective was poisoned when he was alone in a room with someone else. Your job is to track where everyone was, when they were there, and eventually determine which character found themselves alone with the detective.

To uncover this information, the game uses another clever punch-board system reminiscent of Turing Machine, though thankfully, this system is much simpler to wrap your head around. When you want to investigate something, you pick a room, and then combine the room with either a character, and a time period, then place the corresponding punch cards together before flipping them over. The overlapping holes reveal information about that combination, giving you clues about where someone was or wasn’t during a specific moment. What’s particularly interesting is that when you ask a question in a multiplayer game, some of the information you uncover is private, while some of it must be shared openly with the table. Everyone gets a small piece of the puzzle, but you might receive a slightly more precise insight that helps you get ahead of the pack.

I really enjoyed playing Kronologic. The rules are straightforward, the setup is small, and the puzzles themselves manage to create that satisfying feeling of deduction throughout the entire experience. Because every character must move to a different room at each time step, the logic starts to unfold in interesting ways. Once you know where someone definitely was at one point, it constrains where they could possibly be later, and slowly the possibilities begin to collapse in on themselves. If you remove the impossible, whatever remains, however improbable, must be the truth. There’s a good sense of progression as you start to piece together the timeline of the evening, marking down your deductions and watching the puzzle reveal itself in front of you.

The moment when you think you’ve cracked the case, when you’re ready to declare exactly when and where the poisoning occurred and who was responsible, is genuinely exciting. That feeling mostly comes from the fact that you arrived at your conclusion before everyone else did, and so you can rub it in their faces. Sometimes that happens because you simply asked the right question at the right time. Maybe you just happened to pick the one character who actually mattered and asked about them early, which then gave you just enough information to unravel the rest of the puzzle. Meanwhile, your opponents might have spent their early turns investigating characters who ultimately had nothing to do with the crime. In that sense there is definitely some luck involved, particularly in the opening turns when you’re still feeling around in the dark for a useful thread to follow.

That early randomness can make some of the choices feel somewhat arbitrary at first. You’re often picking a character simply because you don’t like their vibe, because they seem as good a place to start as any. But I suppose that’s also thematically appropriate. A good mystery always has its share of red herrings, and part of the detective’s job is to follow the logic rather than their instincts. Someone might give off suspicious vibes, but that doesn’t necessarily mean they committed the crime.

What I appreciate most about Kronologic is how directly it addresses the issues I had with Turing Machine. The setup is dramatically faster; eighteen cards on the table and a sheet of paper to start scribbling your deductions on, then you’re ready to go. Kronologic also avoids that solitary puzzle feeling, because every question you ask leaks a little bit of information to your opponents. Even when someone else is taking their turn, you’re paying attention to what they’re investigating and what that reveals. That small layer of shared information creates just enough interaction to make the experience feel communal rather than parallel.

My biggest concern with Kronologic has to do with its long-term replayability. And maybe it’s a little rich for me to worry about long term replayability as I tend to play most games a mere half a dozen times before moving on to the next new shiny thing, but the difference between Kronologic and Turing Machine is stark. Turing Machine boasts over 7 millions puzzles, meaning you could do 5 puzzles a day for 3,835 tears before running out. Kronologic, on the other hand, comes with three main puzzles, and each puzzle has six variations, or difficulty levels. Once you’ve solved them, that’s kind of it. You know the answers. Unless you’re like me and manage to forget the details after a few months, those particular mysteries aren’t going to surprise you again.

That said, there are already two other Kronologic boxes available using the same system (Cuzco 1450 and Babylon 2500), which I’m glad to see. I also saw some PNP puzzles on Kronologic: Paris 1920‘s BGG page. I genuinely enjoy the physicality of the deduction here, and I’m curious to see how the other scenarios differ from the Paris 1920 setting I played.

In the end, while I still think Turing Machine is the more astonishing production, the cooler toy to hold in your hands, Kronologic is the better game. It captures that classic deductive thrill of piecing together a mystery while adding just enough shared information to keep everyone engaged in the same puzzle. If you have any fondness for old-school mystery games like Clue, Kronologic gives off very similar vibes, but in a way that feels fresher and more satisfying to unravel.
