Quick Answer
Yes, if you love whodunits. Case Closed is one of the best pure mystery manga around, with clever, fair-play puzzles and a fun hook. But it's enormous and episodic, and the overarching plot moves very slowly, so it's better as a series you dip into than one you marathon for the main story.
Quick Verdict
“Hundreds of clever, play-along mysteries wrapped around a glacial main plot — built for dipping into, not bingeing.”
Best for: Mystery fans who want clever, fair-play whodunits and don't mind a huge, episodic series.
Not for: Readers who want a tight, fast main plot or a story they can finish quickly.

Case Closed, known in Japan as Detective Conan, runs on one of the great hooks in mystery manga. Shinichi Kudo is a high-school detective who's already famous for cracking cases the police can't. Then a shady crime syndicate forces an experimental poison down his throat. Instead of killing him, it shrinks him into a grade-schooler. He hides his identity under the name Conan Edogawa, moves in with his childhood friend Ran and her bumbling private-eye dad, and keeps solving murders while quietly hunting the people who did this to him. (VIZ's English release swaps in Americanized names like Jimmy Kudo, but it's the same series.) Gosho Aoyama has been drawing it since 1994, and it's still going.
The cases are the point, and they hold up. Most of them play fair: you get the clues, the timeline, and the suspects, and a sharp reader can take a real crack at the solution before Conan lays it out. That fair-play approach is harder than it looks, and Aoyama has kept it up across an absurd number of stories without running dry. The alibis, the locked rooms, the little inconsistencies stay inventive even hundreds of chapters in.
The central gimmick does a lot of quiet work too. A genius adult stuck in a kid's body lets the series run mystery, comedy, and slow-burn tension at once. Conan has to solve the case and then find a way to point the adults at the answer without blowing his cover, usually by knocking out Ran's useless dad and "channeling" the deduction through him. It's a reliably funny engine that never really gets old.
And it's welcoming. Because almost every case is self-contained, you can open just about any volume and get a complete story. You don't need to memorize a hundred plot threads to enjoy an afternoon's reading, which is rare for a series this long.
The size is the obvious catch. This is one of the longest manga ever made, and the case-of-the-week rhythm that's so easy to dip into can feel repetitive if you try to marathon it. The bigger issue for some readers is the main plot: the syndicate Conan is chasing, and his hope of turning back, advances at a glacial pace, so if you're reading for that payoff you'll be waiting a very long time. Relationships and character growth are mostly frozen for the same reason, since a series that never ends can't let its cast move on. None of this stops the individual mysteries from being good, but it does shape how you should read it.
Case Closed is one of the best pure whodunit manga there is, and the clever, fair-play cases are why it's lasted this long. Treat it as a series to dip into for great standalone mysteries rather than one to binge for the overarching story, and it's an easy recommendation. If you want a tight plot you can finish, or fast movement on the main mystery, the sheer scale will test your patience.
Strengths
Weaknesses
A deduction-driven cat-and-mouse where the fun is watching smart people outthink each other.
A sharp lead solving self-contained mysteries rooted in clues and social rules.
A slower, darker mystery-thriller for when you want one long case instead of many short ones.

Not strictly. Most cases stand alone, so you can sample almost anywhere, but the syndicate plot and character beats reward reading in order.
No. It has been running since 1994 and is still ongoing, with well over 100 volumes.
VIZ's English release, Case Closed, Americanizes the names (Shinichi Kudo becomes Jimmy Kudo, for example). It's the same story.
