Are you stuck on the Pizzeria Weekly Case in Roblox Detective Duck? This investigation includes locked doors, hidden lockpicks, keypad puzzles, and evidence that you must collect before identifying the culprit. If you know where to look, you can solve the case without spending too much time searching every corner.
The tricky part is that the weekly case can have different puzzle combinations. Sometimes you need to copy a pattern onto a keypad, while other times you must collect rotten tomatoes and use a blender to make acidic juice. The general objective remains the same, but the items and codes can change between rounds.
Detective Duck Pizzeria Weekly Case Walkthrough – All Puzzles, Codes, and Suspect Solutions
In this guide, I will explain how to unlock the kitchen, find the required items, solve the different keypad puzzles, and collect all the evidence. We will also cover the recorded codes and show you how to identify the correct suspect using the refrigerator fingerprint.
How to Unlock the Kitchen in Detective Duck
When you enter the Pizzeria case, start by looking around the room. You should search for a locked door, a keypad clue, and a box that may contain a lockpick.
You cannot open the locked door without the required item, so your first job is to solve the nearby puzzle and obtain the lockpick.
Solve the First Keypad Puzzle
Look for a clue displaying several highlighted positions. You need to reproduce the same arrangement on the white keypad found elsewhere in the room.
Follow these steps:
- Inspect the pattern clue and remember the highlighted positions.
- Find the white keypad in the room.
- Click the positions that match the pattern.
- Double-check the arrangement before finishing.
- Open the box and collect the lockpick.
The pattern may differ between rounds, so follow the clue available in your current investigation rather than entering a random combination.
Use the Lockpick to Open the Door
Once you have collected the lockpick, return to the locked door and interact with it.
The lockpicking challenge has three stages. You must complete all three successfully to open the door. If you miss one, try again until you finish the sequence.
After opening the door, enter the kitchen or storage area and start searching for the next lockpick and code clue.
Find the Second Lockpick and Unlock the Next Area
The kitchen contains more items and puzzles that you need to complete before moving on to the investigation.
Search the room carefully for another lockpick. Check the nearby surfaces and accessible areas instead of rushing straight to the next door.
Once you find it, interact with the lock and complete the three lockpicking stages again.
After opening the lock, look for a book or another object containing a numerical code. The code is needed to complete this part of the puzzle.
First Code: 3831
In one of the puzzle setups, the code is found inside a book.
<box border radius=”lg” padding={3} gap={1}> <text color=”secondary” size=”sm”>Recorded keypad code</text> <title size=”2xl” color=”success”>3831</title> <text size=”sm”>Enter this code into the correct keypad when it matches your in-game clue.</text> </box>
Enter 3831 into the keypad and confirm your answer. If the code is correct, the game will accept it and allow you to continue.
Keep in mind that this code belongs to one particular setup. If it does not work in your round, search for the numerical clue in your own game.
Second Code: 7068
Another setup uses a different keypad pattern and numerical code. Solve the pattern, collect the lockpick, and open the required door before searching for the code.
The recorded code for this setup is:
<box border radius=”lg” padding={3} gap={1}> <text color=”secondary” size=”sm”>Alternative keypad code</text> <title size=”2xl” color=”success”>7068</title> <text size=”sm”>Use this combination only if it matches the clues in your current round.</text> </box>
Both 3831 and 7068 worked in the setups covered by this guide. Since the weekly case can change, always check the clues before entering either combination.
Blender Puzzle: How to Make Acidic Juice
Not every round follows the same lockpick and code sequence. In another setup, you will find a blender in the kitchen.
When you see the blender, search for rotten tomatoes scattered around the room. You need four tomatoes to prepare the acidic juice required for the next puzzle.
Collect Four Rotten Tomatoes
Look around the kitchen and collect all four rotten tomatoes. Check the counters, nearby objects, and corners if you are having trouble finding the last one.
Once you have collected all four, return to the blender.
Make the Acidic Juice
Follow these steps to complete the blender puzzle:
- Interact with the blender.
- Place all four rotten tomatoes inside.
- Wait for the mixture to be prepared.
- Collect the acidic juice.
- Take the juice to the special box that requires it.
The acidic juice allows you to open the box and continue the puzzle. Depending on your setup, you may find a lockpick or a clue for another keypad inside.
Make sure you collect all four tomatoes before returning to the blender. If you are missing one, the puzzle will not progress as expected.
How to Solve the Colored Keypad Puzzle
After using the acidic juice, inspect the box and look for any pattern clue inside. In one setup, the box reveals a pattern that must be entered on a colored keypad elsewhere in the kitchen.
The solution depends on the exact arrangement shown by the clue.
Here is how to solve it:
- Examine the pattern carefully.
- Find the matching colored keypad.
- Reproduce the highlighted positions from the clue.
- Check the bottom section for any additional marked positions.
- Submit the pattern and confirm that the puzzle is complete.
One of the recorded arrangements included three highlighted positions across the upper section and another position below. However, make sure you follow the actual pattern displayed in your game rather than relying on this description alone.
What to Do if the Keypad Is Difficult to Click
Some keypad buttons can be awkward to select, especially when the camera is positioned at the wrong angle.
If a button does not register, try moving closer or adjusting your camera until you can click it properly.
Also, double-check every position before submitting the pattern. Missing a single highlighted mark can cause the puzzle to fail, even when the rest of the arrangement is correct.
Once the keypad accepts the pattern, you can move on to collecting evidence.
All Evidence Locations in Detective Duck Pizzeria
Solving the puzzles is only one part of the investigation. Before you can identify the suspect, you must collect the required evidence around the kitchen.
You will need two tools to complete this task:
- UV light: Use it to reveal hidden evidence.
- Magnifying glass: Use it to inspect clues scattered around the room.
The evidence locations are generally consistent across the setups covered here, so remembering the main search areas can save you time.
Where to Find the Evidence
1. UV light area
Start by using your UV light to reveal the first hidden piece of evidence. Check the area carefully before moving on.
2. Cashier counter
Search around the cashier counter for additional clues. Check nearby surfaces rather than looking only at the center of the counter.
3. Table
Inspect the table and the objects around it. Evidence can be easy to overlook if you rush through the room.
4. Refrigerator
The refrigerator is particularly important because it contains fingerprint evidence that can help you identify the suspect.
5. Sink area
Check around the sink for another piece of evidence. Make sure you inspect the nearby surfaces as well.
6. Remaining kitchen surfaces
Search the other accessible areas of the kitchen, including nearby counters and corners. This final sweep can help you find any evidence you missed earlier.
I recommend checking each area before ending the investigation. Even after solving every puzzle, you still need to gather the necessary clues to complete the case.
How to Identify the Correct Suspect
Once you have collected the evidence, you need to determine who is responsible for the Pizzeria case.
One of the most useful clues is the fingerprint on the refrigerator. Inspect it carefully and check which character it belongs to before choosing your suspect.
The suspect can change between setups, so always follow the evidence in your current round.
Suspect Solution: Lucy the Cashier
In two of the recorded setups, the refrigerator fingerprint belonged to Lucy the Cashier.
If the fingerprint in your investigation identifies Lucy, follow these steps:
- Inspect the refrigerator fingerprint.
- Confirm that it belongs to Lucy the Cashier.
- Make sure you have collected the required evidence.
- End the investigation.
- Select Lucy as your suspect and submit your vote.
Lucy was the correct suspect in both of these setups.
Suspect Solution: Sophia
In another setup, the refrigerator fingerprint belonged to Sophia instead.
To finish this version of the case, inspect the fingerprint and confirm Sophia’s name. Once you have gathered the necessary evidence, end the investigation and vote for Sophia.
Do not automatically select Lucy because she was the correct answer in previous rounds. The fingerprint is the important clue, and you should always verify the name before submitting your answer.
Common Mistakes to Avoid
If you are having trouble completing the Pizzeria Weekly Case, check these common problems before starting over.
- The box will not open: Check the highlighted positions and make sure your keypad pattern matches the clue.
- The door remains locked: Confirm that you have collected the correct lockpick and completed all three stages.
- The numerical code does not work: Search for the code clue in your current setup. The combination may be different.
- You cannot make acidic juice: Collect all four rotten tomatoes before using the blender.
- A keypad button will not register: Change your camera angle or move closer to the keypad.
- You cannot finish the investigation: Search the kitchen again and make sure you have collected all the required evidence.
- Your suspect vote is incorrect: Inspect the refrigerator fingerprint and verify the character’s name before voting.
These small checks can save you from repeating puzzles unnecessarily.
