You really wouldn't think this would work as well as it does. Taipei-type tile puzzle, but as you solve it you get randomly-generated "clues" to logic out who done it. One time a guy was murdered by three women who were each missing a leg, acting together.

The minigames are optional (they give more clues) but they're fun; there's a memory game, Fake Tetris and some kind of speed thing that isn't particularly difficult. Still, it's a lot of terrible ideas that, all put together, make a really good, compelling whole. Way better for that Mahjongg itch than most of the ones with over-the-top pseudo-Asian themes.

It's a game of Majhong and I've been really into the game since I played it years ago on my Gameboy. But here, contrary to many other games, tiles are used to collect clues about a crime, the suspects, etc.. The scenarii are always different and like the game Criminal Cases on Facebook, with these clues, it's up to you to arrest the right people.

The soundtrack is good, the gameplay is good, the graphics are decent and the game is right balanced. But why do you sense that I will bring a problem?

Well, you have minigames with it. A sort of Dr. Mario clone to check DNA, a pursuit, interrogations that are matching pairs... And it's these minigames that are a weak link:
- The Dr. Mario clone is controlled by the arrows and not the mouse. I had an hard time to adjust.
- The pursuit, while easy, is at least bugged. One tile stayed, I saw the suspect's car pass through the police one and disappear of my screen on the left while the police kept going to the right. I had to stop the pursuit because I was kinda stuck in limbo

And I still didn't understand the paper tile. I never saw anything going with the press for example. However, the clues are really hepful: you can clear people from a crime easily, even when you have 4 perpetrators (the hair color or the blood type are what you're searching the most). My only downside in that matter is the fact that weight and height aren't in my metric system, which means that I can't say if the suspect is of "average, short, light" etc.. So, unless you're familiar with both systems, you can kiss goodbye to these clues.

I'm enjoying it so far. However, given the fact that the game is nearly reaching the 10 years old mark, keep in mind that maybe, you'll have a problem to play this game (in other words, resolution).

Oh and it works under Windows 8.1 :).

I can't even remember how I ended up with this game, but I just tried it out, and I'm impressed. It's nothing flashy, but it's solid. As you solve Mahjongg boards (with non-traditional tiles), some tiles give you clues toward solving a mystery. Your goal is to make a Carmen Sandiego/Guess Who-style identification of the suspect(s) based on identifying details and obtained clues.

I enjoy Mahjongg, and I enjoyed this. It's a fun game, with straightforward puzzle gameplay and tutorials to gradually introduce you to your crime-solving tools.

MI:US is a cross between Mahjongg solitaire and "clue".

I wish it was back in the 90s, when 800x600 was a good resolution for a 14" monitor. I would have loved this game then. As it stands now, I have the choice of either "too small" (windowed on my 24" monitor), eye-bleedingly filtered/ pixelated at a full-screen resolution, or reducing my desktop to 1360x768 and playing windowed. The use of rendered background images instead of photographs or 2D art is also very 90s.

It's a good game, but unfortunately, unplayable for me.

Mahjongg Investigations: Under Suspicion is a really fun and interesting take on the traditional game of Mahjongg. As you match pieces, you unlock clues, uncover evidence, confirm alibies of various suspects and more, leading up to the moment you are ready to get a warrant against the perpetrator of whichever case you happen to be on. Each case begins with the initial crime scene where the timer begins. As you successfully complete each location, additional time is added to the clock. Once you have amassed enough clues and feel you are ready, you can review the clues, evidence and suspects, prior to requesting a warrant.

I thought this was a really good way of adding a new dimension to the classic game of Mahjongg. I consider games like this to be "Time Wasters", something one does when they are bored and looking for something to do, when you don't really want to get to involved in a game. It is a good game, and I am glad I picked it up. There is only one level of difficulty and the way the game is setup, you have an evidence bag which can hold a few tiles at a time making it almost impossible to not be able to clear a board. In any case it is still fun to play.

This is two games in one... part mahjonng and part whodunnit. The mahjonng part is what you'd expect, with traditional tiles switched out for modern tiles. However, the whodunnit part kicks in by adding clue discovery, facts about suspects, and suspect elimination as you progress through boards in different locations on each case. There's also an occasional car chase mode which involves matching tiles before the suspect gets away, as well as the interrogation mini-game, which is essentially the memory game. As you nab suspects, you gain rep and get promoted.

It's not terribly challenging, but it's not meant to be. It's a nice diversion that can become a little addicting.

Overall, Mahjonng Investigations isn't spectaular, and the graphics would have been unimpressive a decade ago. But, who cares? What it does it does extremely well, and it's one of those casual games that makes me want to do "just one more" before quitting.

All that said, at $9.99, I'm not sure you'll get value unless you specifically enjoy mahjonng. I got my game in a bundle... so keep an eye out in the usual places for that. I'm giving it a positive with no reservations, as I would have felt the price was okay if I had paid full for it.

Love this game. MY granddaughter loves to play too. I like how you are given vairous way to find using a tetris style gameplay, also by matching, and then of course mahjongg. If you like Mahjongg and problem solving. And don't want a game requires you to shoot anything, or build anything. This is your game.

The game was simple, but pretty fun when I first played it. It was buggy then, and I posted in the Steam Discussions page, and there's been no response ( ).

Several months later I tried it again, and it won't even start.

Don't get it unless the devs get their ♥♥♥♥ together.

A mildly entertaining game, though I'd recommend to get it on a sale / bundle instead of full price.

+ deductive gameplay
+ special tiles
+ interrogation minigame (memory puzzle)

- the basic gameplay gets repetitive very quickly
- somewhat annoying background ambient sounds
- there are only a handful of case types, which repeat a lot

6.3/10 - Murder Mystery Mahjongg

This is an interesting take on Classic Mahjongg. As you match tiles you uncover clues to determine the killer. You have about 25 minutes to collect enough clues and get warrants to perform searches. With multiple locations and tons of potential targets this game has a good replay value.

This would be a good game to end the night on or just to unwind. I personally wouldn't pay $10. If you like Mahjongg then $5 would be reasonable.

Others have described exactly what you do in the game, so I won't go into that.

What I will say is I enjoyed this game immensely and will probably return to it from time to time. The atmosphere is set well, there's a lot of different elements and a few minigames that all gel well together. Even though the countdown timer should never have been a concern to me, its presence did make everything feel more urgent (which is something that really annoys me in most games, but didn't in this one).

The one negative is the continuous pop-ups of each new piece of information (Ted Whatshisface weighs 122 pounds!) gets a little annoying towards the end, particularly since with four perps and 20-ish suspects, you don't (and can't) really care about each piece of information but what it all tells you when combined on the case info page. There really should be an option to turn that off.

Actually, I tell a lie. There is a second negative, if you're playing the minigame where you're chasing a suspect and you manage to clear all the tiles before the last one appears, it glitches and you can't catch the suspect. Solution is, when you get down to the last two tiles to wait for them both to appear at the bottom of the screen before clearing them.

I bought it on sale, and while I would pay for it at full price, this game probably isn't for everyone. I'd recommend waiting for a sale.

The idea sounds silly, but the game is surprisingly engaging. Combines some of the simple suck you in power of solitaire/mahjonng, but with a bit of a carmen sandiego twist, that combined with the atmospheric details such as the poilce scanner, keep me interested. I'm not someone who cares much for story in games, so the simple modular way of telling a "story" keeps the text light, but still makes you feel like some sort of weird detective. My only complaint is that I have NO idea what average height, weight, light build, etc means.

The Valu-Soft branding should be a warning here.

This is ostensibly a mahjong tile matching game but linked to some plot where you play mahjong to uncover evidence to get the bad guys.

Unfortunately the graphics are bad, overscan/DPI issues prevent fullscreen from working, it really misses the mark. There's better mahjong games.

You unearth clues by playing Mahjongg and use those to arrest criminals. Definitely not worth it for the full price, but on discount it's a fun Mahjongg game with a twist, especially if you enjoy the detective genre.

Absolutely excellent semi-casual game, gives a very good investigation feel and has decent variety. Each case contains:

*) Multiple locations to check out, each of which corresponds to a separate mahjong solitaire puzzle. Solve slightly-easier mahjong to get clues. Generally, more puzzles are available than you'll need, and you can try to solve the case at any point.
*) Use clues to identify suspects as perpetrators -- there's different kinds. You can discover new suspects or find alibis that rule out old ones, you might learn facts about the suspects, or the perpetrator, and perpetrator facts are solid enough but vague enough that you actually have to think about it. What is "average height"? Obviously the 4'11" girl can go, but what about the 5'9" one? It strikes a delicate balance.
*) Interrogate suspects for more clues -- which is a Memory minigame with yet more tiles. Turn over tiles two at a time, trying to find matches. The better you do, the more facts you get about that suspect -- or, they might even confess under pressure.
*) You have a phone, which occasionally gets anonymous tips or clues from the lab -- which tends to go off when you're busy doing something else, making it mildly (but not terribly) more difficult to concentrate on the puzzles.
*) Smooth and easy to use interface makes the logic puzzle segment a breeze to interact with, while the multiple suspects and the nature of the clues ("at least one suspect has bloodtype AB+" : if there's two suspects, you can't rule out other bloodtypes, but when one suspect has several suspicious traits...) keep things novel and interesting.

It fits a lot of genres I like together into one thing. Casual puzzles, tacked together with just enough narrative to make each one have meaning and context, and enough variety and inter-relatedness to keep it interesting.

My only critique is that it could possibly use more suspect portraits, or be more careful about which one gets assigned where (double-chin lady probably shouldn't be described as having a light build, for example), but that's minor.
