The Summer Camp case in Detective Duck drops you at Forest Hills Camping Site with one job. A teacher was hurt by a rigged rock trap at an off-limits abandoned house, and you need to gather clues, solve four locked puzzles, and name who set it. The catch is that the game will not let you end the investigation until every suspect profile is filled in, which is why so many players get stuck at the finish line.
Quick answer: Enter 1573 at the reception locker, shoot the archery targets in the order 1 → 2 → 3 → 4 → 5, match the grid colors (Duck = Green, Log = Brown, Arrow = Blue, Fire = Red), enter 844 at the back gate, then vote for Liam at the end.
All Summer Camp codes and puzzle answers
If you only need the solutions, here they are in one place. The rest of the walkthrough explains where each one comes from and the items you need to reach it.
| Puzzle | Answer |
|---|---|
| Reception locker code | 1573 |
| Archery target order | 1 → 2 → 3 → 4 → 5 |
| Symbol grid colors | Duck = Green, Log = Brown, Arrow = Blue, Fire = Red |
| Back gate code | 844 |
| Correct suspect | Liam |
Starting area: rock, charger, and the 1573 locker
1573. Enter it on the locker to open it and take the Gate Key.
Archery targets and the raised rock
Symbol grid color puzzle
The poster on the cabin porch tells you which color belongs to each symbol. Read it, then return to the color grid panel beside the cabin door and place each color in the same spot the hidden grid showed.
| Symbol | Color |
|---|---|
| Duck | Green |
| Log | Brown / Orange |
| Arrow | Blue |
| Fire (Campfire) | Red |
With the positions and colors matched, the puzzle opens the cabin door. Inside, search the suitcase to get the Special Toy Knife. This search also unlocks new suspect files, so do not skip it.
Collect all six notes and unlock the 844 gate
The six investigation notes are scattered across the camp. Your inventory holds only nine items at once, so if it fills up, head back to Reception, drop notes on the board, and keep collecting.
- Note 5 sits in the grass behind the cabin.
- Note 6 is on a shelf inside Reception.
- Note 4 is on the large rock, and Note 3 is on a cabin porch.
- Note 2 is on a picnic table near the front gate.
- Note 1 is inside the locked red trailer in the parking lot.
Read the Reception Book on the desk first. It tells you the Special Toy Knife opens the red trailer, which is how you reach Note 1. Use the knife on the trailer, grab the note, then finish gathering the rest.
Once all six notes are placed on the investigation board, the code 844 appears at the bottom. Enter 844 at the locked back gate to open the cave path toward the campsite.
Campsite: Burnt Note and the last suspect profiles
Abandoned house and naming Liam
Travel to the graveyard area, open the wooden gate, and kick down the door of the abandoned house. Inside, a heavy rock is rigged to the ceiling with rope over a fallen chair, which is the trap that injured the teacher. Inspecting it completes the investigation area.
The evidence all points one way. Simon states that Liam planned something at the abandoned house as revenge; the restored Burnt Note references that same house, and another profile notes the teacher went searching for Liam and was hurt. Other suspects mostly clear themselves, so Liam is the culprit.
Equip the phone, select END INVESTIGATION, then in the voting room choose Liam (Student) and confirm your vote. You will see “Liam (Student) was most voted,” followed by Liam shown behind bars with a court document listing his charges. That screen confirms you solved the case correctly.
If the END INVESTIGATION option is greyed out, you are missing suspect information. Go back and search anything interactive you skipped, especially the Reception Book, the campsite book, and the suitcase, since each one unlocks profiles you need before the game lets you accuse anyone.
