Unsolved: Hidden Mystery Games

Review by eFreeware

The most distinctive thing about Unsolved is that it is not one mystery but a shelf of them. Artifex Mundi has bundled a set of its hidden object adventures into a single free Android app, so you pick a case, work through it, and then move on to another without installing anything new. The developer describes it as an expanding collection, with further titles promised inside the same application.

That structure shapes who the app suits. If you already enjoy searching cluttered, hand-painted scenes for a list of objects, and you like those searches wrapped in a story about a disappearance, a murder or a family secret, this is built for exactly that appetite. It is a free download with ads and in-app purchases, so there is no cost to see whether the format holds your attention.

It is also a sensible fit for players who want a mystery to carry across several short sessions rather than one long evening. The developer says the games are optimized for phones and tablets and suited to playing while traveling, which points to something you can open for ten minutes, find a few clues, and put away again.

Where the stories take you

The collection opens with the Eventide trilogy, which the developer presents as the starting point and includes an exclusive bonus chapter. You follow Mary Gilbert as she travels to eastern Europe and runs into Slavic folklore and an unearthly threat, learning about her heritage along the way. It is a specific, atmospheric hook rather than a generic ghost story, and it gives the collection a clear first destination.

Beyond that, the settings shift widely. The places you visit include a mystery manor, a city alley, a hotel and a dungeon, and the scenes you search include a crime scene, a haunted hotel and an enchanted forest. Some cases lean toward crime, others toward the supernatural, and the app asks you to decide which it is as you go.

The collection also draws on titles from Artifex Mundi's back catalog. Noir Chronicles: City of Crime puts you on detective cases, Crime Secrets: Crimson Lily leans into crime drama and character work, The Myth Seekers: The Legacy of Vulcan heads for ancient secrets in picturesque locations, and Grim Legends: The Dark City sets you the task of saving a city from an ancient curse. These are presented as examples of what sits inside Unsolved, and each brings its own tone to the shelf.

How a case actually plays

The core loop is detective work built on hidden object scenes. You explore illustrated locations looking for clues and useful objects, and finding them moves the investigation forward. The scenes are described as heavily detailed, which is the point: the challenge comes from picking small items out of busy artwork rather than from anything timed or reflex-driven.

Between searches, you work through puzzles. These are varied, and you lead the inquiry, document evidence and use deduction to get inside the minds of the people you are chasing. That framing suggests a mix of searching, assembling what you have found and reasoning about what it means, rather than pure object-hunting from start to finish.

The stories themselves carry the pace. The tales cover unexplained vanishing, murder and dark family secrets, with characters who are sometimes friendly and sometimes hostile. Whether a given case turns out to be a crime or something stranger is part of what you are meant to work out, and the collection is pitched as holding your attention from beginning to end.

Why the shelf keeps growing

The appeal of a collection like this is variety without friction. Instead of finishing one mystery and then hunting the store for another, you finish one and start the next from the same place. Unsolved is an ever-growing set, with new in-app releases planned for the future, so the value is meant to accumulate rather than sit still.

There is also a range of mood on offer. A crime drama, a cursed city and a folkloric journey through eastern Europe do not ask the same thing of you, and switching between them keeps the format from wearing thin. Players who like one style more than another can gravitate toward the cases that match it.

The scenes do a lot of the work here too. The scenery is hand-painted, and in a genre where you stare at the same location for a long stretch, the artwork has to reward that attention. The list of venues, from manor to dungeon, suggests the collection was built with that in mind.

What it costs and what comes with it

Unsolved is free to download and contains ads. It also offers in-app purchases. This is an ad-supported free app rather than a one-off paid title.

It is described as free hidden object adventures gathered in one place, with additional titles arriving over time, which is consistent with an app that grows and monetizes as it goes.

The content rating is Teen, which fits the subject matter: murder cases, unexplained vanishings and supernatural threats are the raw material here. It is not pitched at younger players, and the stories are meant to carry some weight.

A collection with a long history behind it

Unsolved arrived on Android in December 2019 and has been updated since, most recently in October 2026 with minor improvements aimed at smoother gameplay. That is a modest note, but it signals that the app is still being tended rather than left as it was at launch.

The install figures back up how widely the format travels. More than 10 million installs and a 4.7 average across 489,168 ratings put it in the company of apps that a great many people have tried and, on the whole, rated well. Those numbers describe the app as a whole rather than any single case inside it, but they are a reasonable indication that the core loop lands with a broad audience.

The developer's pedigree is part of the pitch as well. Artifex Mundi is behind the Enigmatis and Grim Legends series, and Unsolved gathers titles from that portfolio alongside the Eventide trilogy. If you have played any of those before, you know roughly what kind of pacing and presentation to expect.

A mystery shelf worth opening

Unsolved makes most sense for players who already like hidden object adventures and want a stack of them in one place. The combination of detailed scenes, puzzle work, detective framing and a rotating cast of stories is exactly what the genre does well, and bundling it means you are never short of a next case. The Eventide trilogy gives you a defined starting point, and the wider collection gives you somewhere to go afterward.

It is free with ads, it carries in-app purchases, and it is rated Teen. If you want a single self-contained story rather than a growing library, or you would rather avoid ads entirely, those are real considerations. For everyone else, this is an easy download to try, and the install and rating figures suggest plenty of people have found it worth keeping.
