This Motel page is a full Detective Duck case walkthrough for players searching detective duck motel answers: search order, puzzle codes, suspect logic, and the final accusation. Crime setup: Lobby register forced overnight; a guest also claims jewelry theft.

| Fact | Detail |
|---|---|
| Case | Motel |
| Crime | Lobby register forced overnight; a guest also claims jewelry theft. |
| Correct culprit | Dentist (Room 2) |
| Keypad | 0146 |
| PC login | night shift / late checkout |
| Crime window | About 2:00–4:00 a.m. |
| Wrong-accusation trap | Believing the dentist is a victim because he reports a stolen necklace — the log proves the claim is false cover. |
| Next | Museum case |
Unlock every guest room and the pool PC before you trust anyone’s story.
After each major unlock, glance at suspect roles and alibis. Detective Duck cases are built so the map puzzles and the accusation are two halves of one loop — finishing locks without reading statements is how players soft-lock themselves into a guess.
If you play co-op (up to five on a public server), split “search left / search right” and call out room names so nobody double-clears the same drawer row.
Any time the prompt hints at tiny marks — footprints, wall ticks, stains, keypad smudges — equip the Magnifying Glass before you move on. Several Motel clues only exist at that zoom level.
Mobile players should pinch-zoom the Case File text after big finds; small alibi contradictions are easy to miss on a phone screen.
Backtrack one room and re-check posters, toilets, corkboards, and “staff only” doors. Motel almost always hides the next tool one interaction behind an object you already passed.
Also re-open the case brief on the phone. Detective Duck briefs quietly restate the crime window, the missing object, or the “no alarms” detail that later proves an inside job — players who skip the brief invent theories the map never supports.
Solo clears are slower but safer for reading every note. Co-op (up to five public, ten on private servers) shines when one detective calls codes while another watches the Case File — never let two people enter different keypad guesses at once or you will burn attempts and confuse which string was correct.
Private servers help when a friend is learning Motel for the first time: pause at each checklist item, confirm the tool is in inventory, then move. That teaching loop is faster than wiping a wrong accusation badge later.
These are in-game puzzle codes for the Motel map, not Roblox redeem codes. Use Copy, then paste on the keypad. For the full cross-case list see the codes page.
| Code | Where it is used | How you learn it |
|---|---|---|
0146 | Room 4 painting keypad | Digits sorted lowest to highest |
night shift | PC username | Night log / pool computer |
late checkout | PC password | Pairs with night shift |
Confirm you are still on Motel, clear the field, and re-enter digits only. Some doors share a UI with other cases but use different strings.
Passwords that rotate per run (inbox-style) are marked in the table — copy what your monitor shows, not a guide example string.
Puzzle codes unlock doors inside Motel. Roblox promo codes — when the developer posts any — are tracked separately on the Detective Duck codes page so this walkthrough stays spoiler-focused.
He is seen near the pool around 3 a.m. inside the 2–4 a.m. window, and his stolen-necklace story contradicts check-in records that show he declared no valuables.
| Clue | Where | What it proves |
|---|---|---|
| Pool sighting ~3 a.m. | Notes / PC | Dentist inside robbery window |
| Stolen necklace claim | Dentist statement | Contradicts check-in “no valuables” |
| Check-in log | Reception records | Shows he traveled light |
| Other guest alibis | Case File | Line up with timestamps |
A single suspicious prop is never enough on Motel. Wait until the physical clue, the document/log, and the Case File role line up on the same person — that is Dentist (Room 2).
If two suspects still look plausible, re-read opportunity: who could plant a tool, open a gate, or appear on camera at the crime window?
Most players land here from queries like detective duck motel walkthrough, code, suspect, or answer. Skim At A Glance for the culprit, jump to puzzle codes if you are soft-locked on a door, then read the clue table before you vote.
When you need the redeem-code list or other maps, bounce to codes and the cases hub instead of mixing puzzle digits with Roblox promo strings.
Open the phone → END INVESTIGATION → select Dentist (Room 2).
Continue with Museum case, or jump back to the case hub and the chapter walkthrough. For accusation habits across every map, keep the tips page open.
Detective Duck tracks wrong accusations per case. If you already misfired, re-run Motel with this checklist instead of guessing a second name.
Success screens usually confirm you caught the right suspect and may list charges — screenshot that if you are tracking badges, then move to Museum case while the loop is fresh.
