Last Updated: August 2026 | Cases, shop and codes checked against the live game.
Detective Duck makes you a duck in a hat with a magnifying glass. You get dropped at a crime scene, search the rooms, pick up anything useful and question the suspects. Then you name the one who did it and find out whether you were right.
It opened in October 2025 and has passed 52 million visits. This page has every case, the shop, and something you will not find anywhere else: exactly how many people solved each case, and how many arrested the wrong duck.

How to Play Detective Duck
Every case works the same way. The map changes, the job does not.
- Pick a case and drop into the map. Start by walking the whole place once.
- Pick up anything that can be picked up. Half the answer is usually an object.
- Question every suspect, including the boring ones.
- Compare what they told you. Two stories that do not match is the usual giveaway.
- Make your arrest. Get it right and you get the solved badge for that case.
- Get it wrong and you get a badge for that too. Millions of people have it.
Detective Duck Gameplay: The Modes
The cases are the main game, but they are not the only thing in here.
| Mode |
Who |
What it is |
| Cases |
1 to 5 players |
The main game. A map, a crime, a handful of suspects and one of them did it. |
| Chapter 1 |
Finished |
Twelve cases and a finale called The Hideout, which has a good ending and a bad one. |
| Chapter 2 |
Coming |
The first case is called The Bakery. Its badges are in the game already. |
| Duck Battles |
Side mode |
A fighting mode with tools and its own currency called quacks. |
| Deception |
Side mode |
A social mode where somebody is guilty and everyone else is trying to finish tasks. |
The side modes have their own money, called quacks, and their own leaderboards. They are much quieter than the cases. Only ten players have ever held the badge for owning the most quacks.
Every Case, And How Many People Solved It
This game hands out two badges per case. One for solving it, one for arresting the wrong duck. Badges are given once per player, so these are headcounts of real people.

Start at the top. About 13.8 million people have played this game and 7.9 million finished the first room, so a bit more than half get past the opening.
Then look at the wrong arrests column next to it. That first room has 3.8 million of them. For every two people who solved it, one has the badge for getting it wrong first.
The Jewelry Store is the odd one out and the easiest case in the game by a mile. Sixteen people solve it for every one who gets it wrong. Nothing else comes close.
The Hardest Cases, And The Game Agrees
Two cases stand out for the wrong reasons. Suburbs and Train both have nearly one wrong arrest for every solve, which is worse than any other case here.
Here is the good bit. The badge for the Train case says on it that the case is extremely difficult to solve. The Suburbs badge says the case is difficult. The developers wrote that themselves, and the numbers back it up exactly.
So if you are stuck on those two, that is the game working as intended. Save your clue for them rather than burning it on an early case.
The Case Nobody Has Solved Yet
Look at the last row of that table. The Bakery is the first case of Chapter 2, and both of its badges already exist in the game.
Neither has been handed out. Not once. Zero people have solved it and zero people have arrested the wrong duck in it, which is the giveaway, because wrong arrests pile up within hours of a case going live.
The badges were made on 12 August 2026. So the next case is built and waiting, and nobody outside the studio can say when the door opens.
How Far Most People Get
Chapter 1 ends with a case called The Hideout, and it has two endings. 83,135 players got the good one and 60,242 got the bad one.
Only 126,863 players have the badge for finishing Chapter 1 at all. Against 13.8 million players that is about 1 in 109.
Coming back is rarer than you would think too. About 8 players in 100 have the badge for returning the next day. The badge for a seven day streak has 1,563 holders, which is about 1 player in 8,900.
What The Shop Sells
Seventeen passes, 1,964 Robux for all of them, and only three make any difference to a case.
| Pass |
Price |
What it does |
| Ask Unlimited Questions |
139 Robux |
Ask any suspect as many questions as you like, forever. |
| Premium Pass |
199 Robux |
A bail bond, a question and a clue handed to you every day. |
| Heartbeat |
49 Robux |
Stops you getting lost while you search a map. |
| Skins and bundles |
39 to 199 |
Eleven of them. Alien ducks, angels, monsters, a duck in a pizza box. |
| Themes and an emote |
49 to 99 |
Menu themes and one suspicious little animation. |
| Side mode tools |
39 to 99 |
A soccer hand, a power glove and double quacks. These only work in the battle modes. |
Nothing here unlocks a case or names a culprit. The three useful passes give you more questions, a daily clue and a way to stay found. The rest is how your duck looks.
Codes
This game has no reward codes and no box to type one into. The codes people search for are the answers inside the cases, which is a different thing. Our Detective Duck Codes page explains the difference and what the game gives you for free.
Who Makes Detective Duck
It comes from a verified group called Protocol: Anomaly, run by a developer called CookleDeveIoper. The group has more than 390,000 members.
They make one kind of game and nothing else. All four of their games are puzzle or escape games, including two more escape rooms and a puzzle game about bringing the sun back. This one is about 63 percent of everything they have had visited.
There is a badge for meeting each of two developers in game. One has 6,236 holders and the other has 2,673, so they really do turn up in servers.
Tips for New Detective Duck Players
- Search the whole map before you accuse anybody. Nearly every wrong arrest is a clue somebody walked past.
- Bring friends. The game holds five in a normal server and ten in a private one, and clues get spotted faster with more eyes.
- Do the cases in order. The early ones teach you what to look for and the later ones assume you learned it.
- Ask every suspect something. The quiet ones are in the case for a reason.
- Write names and times down. Most of these cases turn on one small difference between two stories.
- Expect to be wrong sometimes. The wrong arrest badges have been handed out more than six million times between them.
- Come back tomorrow. Only about 8 players in 100 ever do, and the game hands out a badge for it.
- Nothing in the shop unlocks a case. If you are stuck it is because of a clue, not because of Robux.
