Unsolved Case

Unsolved Case is a compact, two-player cooperative puzzle game that serves as a free prequel to the Cryptic Killer series and places you alongside detectives Ally and Old Dog as they race to open a mysterious locked box. The app delivers a single focused session of 30–60 minutes of escape-room style gameplay across hand-illustrated noir locations, with no ads or microtransactions, and is designed to test communication, code‑breaking and teamwork in a portable package.

Key features and what to expect

Unsolved Case provides split-screen-style cooperative puzzles where each player sees different clues and pieces of the same mystery; progress depends on the back-and-forth exchange of information. The game includes an in-game notebook and pen that let players jot observations, sketch connections and annotate the illustrated environments. Sessions are intended to feel like a single, intense playthrough rather than a long campaign, so the design favors tight puzzle loops and a clear narrative beat that ends with the locked box reveal. Because both players need their own copy—on mobile, tablet, PC or Mac—and a live voice connection to trade clues, the social element is central to the experience.

Gameplay and controls

Gameplay centers on observation and communication rather than reflexes. On touch devices, players tap to inspect objects, drag to connect symbols, and use simple gestures to rotate or combine items. Desktop and laptop controls mirror this with point-and-click and click-drag interactions. The in-game notebook behaves like a physical pad: you can select pen thickness, mark items, and organize notes into pages that persist through the session. Because the puzzles require constant exchange, voice chat between players is recommended; the game does not provide its own built-in voice service, so players should use a third-party voice app of their choice.

Progression and level structure

The progression in Unsolved Case is linear and session-focused. Players move through a handful of interconnected noir locations—each illustrated and scripted to present different puzzle types, such as cipher decoding, pattern recognition, sequence reconstruction and contextual deduction. Puzzles build on one another, so earlier discoveries unlock later interactions and the final puzzle is a synthesis of information gathered across locations. There are no persistent levels or unlock trees beyond the single prequel narrative, making the title ideal for an evening of cooperative puzzle solving without long-term progression commitments.

Visual style, audio and immersion

The game uses hand-illustrated noir environments to create atmosphere: inked line work, muted palettes and spot lighting set a tense investigative mood without relying on heavy animation. Background audio and ambient soundscapes support focus during puzzle solving, while clear UI elements keep attention on clues rather than flashy effects. Visual clarity is prioritized so that important details stand out for both players; the art is crafted to encourage careful inspection and note-taking rather than quick scanning.

Notebook, customization and replay value

The in-game notebook is more than a convenience—it shapes how teams approach puzzles. Players can toggle pen colors, add multiple pages, and organize notes to try alternate theories. While the core session follows the same narrative each time, replay value comes from different communication strategies, experimenting with how clues are described, and improving coordination to solve puzzles faster or with fewer hints. The game does not promise randomized levels, but the emphasis on collaborative problem solving means each attempt can feel fresh depending on player pairing and playstyle.

Accessibility, user experience and limitations

Unsolved Case aims to be approachable: the control scheme is simple, text is legible, and UI targets are sized for touch play. Players should expect clear feedback from interactions and an in-game help system that explains basic mechanics. Important limitations are upfront: two players are required for the intended experience, each must own a copy of the game, and an active internet connection plus external voice chat are necessary for full functionality. Offline play is not supported because the cooperative design depends on live, synchronous communication.

Compatibility and system notes

The game supports mobile phones, tablets, and desktop platforms (PC and Mac) with matching feature sets; input maps adapt to touch or mouse and keyboard. Because the experience is short and focused, device performance requirements are modest, but a stable network connection is recommended to avoid dropped communication during a session. If you enjoy tightly designed cooperative mysteries that reward careful listening, note-taking and teamwork, Unsolved Case delivers a compact, ad-free introduction to the Cryptic Killer universe.
