Dossier: Detective Game is a new iOS and Android app that drops a brand-new murder mystery every single day — with unique victims, suspects, and killers you've never seen before. Unlike static whodunit games that run out of content, Dossier uses AI-generated cases to deliver infinite replayability, real suspect interrogations, and a one-shot accusation system that makes every decision matter.
If you love Wordle's daily ritual, true crime podcasts, and Cluedo-style deduction, Dossier was built for you. Here's our full review.
What Is Dossier: Detective Game?🔗
Dossier is a daily murder mystery game launching April 2026 on iOS and Android. Its tagline says it all: "A new case. Every day." The game combines the ritual structure of Wordle and NYT Games with the depth of classic detective fiction — giving true crime fans a fresh whodunit to crack every 24 hours.
The free daily case is always available. No energy walls. No waiting. No "watch an ad to continue." Just open the app, read the case file, and start investigating.

How Dossier Works (3-Step Gameplay)🔗
Every case follows the same three-step loop — but the content inside is different every day.
1. Open Your Case File🔗
You start with a fresh crime scene. The case file includes:
-
The crime scene report — where the murder happened, what was found
-
Victim profile — who they were, relationships, routine
-
Autopsy report — cause of death, time of death, forensic details
Read carefully. Every detail matters.
2. Interrogate the Suspects🔗
This is where Dossier separates itself from every other mystery game on the App Store. Instead of tapping through pre-written dialogue trees, you have real conversations with suspects. Ask them anything — but choose carefully, because you only get 5 free messages per suspect.
- Where were you at the time of the murder?
-
Did you know the victim, and how?
-
What's your relationship to [another suspect]?
-
Why did we find your fingerprints at the scene?
Suspects respond dynamically. They lie. They deflect. They contradict themselves. Your job is to catch them — with just 5 messages each, making every question a strategic decision.
3. Make Your Accusation🔗
One chance. No going back. Face the truth.
You pick the killer and commit to your answer. Get it right and you climb the ranks. Get it wrong and the case goes cold — forever.
Difficulty Tiers: From Rookie to Cold Case🔗
Dossier scales with your skills through four difficulty tiers:
| Tier | Suspects | Clues | Time | Best For |
|---|---|---|---|---|
| Rookie | 3 | 4 | ~5 mins | New players, daily free case |
| Detective | 4 | 6 | ~10 mins | Regular puzzle fans |
| Inspector | 5 | 8 | ~20 mins | Experienced sleuths |
| Cold Case | 6 | 10 | ~35 mins | True crime obsessives |
The free daily case is always a Rookie tier. Upgrade to Detective Pro or Chief Inspector for access to harder cases.
What Makes Dossier Different🔗
Most detective games on mobile suffer from the same problems:
-
Static hand-written cases that run out after a weekend binge
-
Energy systems that force you to wait hours (or pay)
-
Hidden object tapping instead of actual deduction
Dossier flips all three:
- Infinite unique cases — never the same twice
-
No energy walls — play when you want, as much as you want
-
Real interrogation — open-ended questions (5 per suspect), not pre-set dialogue
-
Daily free case — no purchase needed to play every day
Progression: XP, Ranks, and Leaderboards🔗
Every solved case earns XP. Stack wins to climb from Rookie Detective to Chief Inspector. Higher ranks unlock:
-
Harder case tiers
-
Cosmetic case file themes
-
Leaderboard bragging rights
-
Streak multipliers for consecutive solves
It's the same dopamine loop that made Wordle go viral — but with the narrative depth of a detective novel.
Pricing: Free-to-Play With Optional Pro Tiers🔗
