Tidy Up History Museum Rooms & Exhibit Halls

The inherited museum in Tidy Up History is a patchwork of specialized halls. Casual Human’s single-player sim spreads content across dinosaur collections and world-history galleries, unlocking them through keys as you restore. This page is your room roster and theme guide — what each area is about, how to approach it, and how it ties to cleaning, labels, skeletons, and Complete [room] achievements. Exact unlock order can vary with exploration; for a campaign sequence use the Walkthrough.

How to use this roster

For every hall:

1. Clean dirt, clutter, and repairs — Cleaning and Repairs.
2. Study knowledge tied to the theme — Knowledge Books.
3. Place artifacts or fossils correctly — Artifacts and Labels.
4. Finish signature mounts if prehistoric — Dinosaur Skeletons.
5. Sweep for keys before calling it done — Keys and Wings.

Mark a room complete only when those five feel honest. That standard supports Complete [room] trophies and Museum Owner progress — Achievements.

Prehistoric halls

Cerapoda

Expect cerapod-focused fossil work and mounts. Prioritize floor clears so small bones appear, then assemble part by part. Treat this as a core Assembler playground.

Theropods

Theropod halls lean into bipedal carnivore silhouettes and dramatic mounts. Watch your carry trips; theropod parts add up. Highlight abilities help when ribs and limbs scatter — Abilities and XP.

Ornithopods & Thyreophorans

A combined theme space: ornithopods and armored thyreophorans. Keep sets separated while staging so you do not mix plates and bipedal limbs on the wrong armature.

Non-Dinosaurian

Not every prehistoric star is a dinosaur. This hall reminds you to finish marine reptiles, pterosaurs, or other non-dinosaurian displays the museum owns. Skipping it stalls When Dinos Ruled the Earth style completion even if classic dinosaurs look done.

Launch roster note: Casual Human’s Steam Deck Ready announcement said sauropods were replaced by non-dinosaurian creatures at launch, with a dedicated sauropod room planned for a future update. Treat Non-Dinosaurian as required launch content—not optional filler while you wait for long-necks. When that future room arrives, it will appear on the Updates Hub; until then, do not leave this wing half-finished.

Human-history galleries

Stone Age

Early tools, lifeways, and foundational human exhibits. Great early practice for labeling discipline. Keep fossils that wandered here moving back to prehistoric wings.

Mesopotamia

Cradle-of-civilization artifacts — tablets, ritual objects, early urban material culture. Knowledge books matter; motifs can confuse newcomers. Stage unknowns until identification lands.

Ancient Egypt

High visual recognizability (and high wrong-placement temptation). Confirm labels anyway. Case lighting repairs make hieroglyph-heavy displays readable.

Ancient Greece/Rome

Classical sculpture, daily life, and civic artifacts. Watch for lookalike ceramics from nearby eras — knowledge first.

Ancient China

A deep material culture wing. Batch placements by case to reduce walking. Do not park Japanese/Korean pieces here “temporarily.”

Ancient India

Distinct sculptural and cultural vocabulary. Use study materials before forcing seats; cross-contamination with neighboring Asian halls is a common mistake.

Ancient Japan/Korea

Shared wing energy with careful internal sorting. Stage Japan vs Korea subsets if the layout offers distinct cases — read labels twice.

Medieval Europe

Armor, faith, and medieval daily life props. Heavy clutter sometimes hides keys; clean thoroughly.

Islamic World

Science, art, and cultural artifacts spanning a wide geography. Treat the hall as its own syllabus; do not dump generic “old world” leftovers here.

Subsaharan Kingdoms

Kingdoms and cultures of sub-Saharan Africa with rich art and regalia. Give this wing equal curation care — it is not optional flavor.

Mesoamerica/Andean

American antiquity spanning Mesoamerican and Andean civilizations. Keep these distinct from Indigenous North America materials when staging.

Indigenous North America

Nations and cultures of North America with their own exhibit logic. Finish this hall with the same Complete [room] seriousness you give Egypt or Theropods.

Cross-wing traffic rules

• Misplaced objects are normal after years of neglect — walk them home.
• Stage by destination door to cut errands.
• After unlocking a new wing, do a reverse sweep of old halls for pieces that now have a home.
• Alternate prehistoric and human sessions if burnout hits; palette shifts refresh attention.

Completion checklist template (copy mentally)

• Dirt cleared
• Clutter gone
• Repairs done
• Knowledge in this wing read
• Artifacts / fossils correctly placed
• Skeletons complete (if applicable)
• Key search done
• Achievement popup or room-complete status noted

How rooms connect to the 25 achievements

Many of the 25 Steam achievements are room-complete variants plus systemic trophies (Curator, Handyman, Keymaster, Archivist, Knowledgeable, Master Cleaner, Assembler, When Dinos Ruled the Earth, Museum Owner). You cannot finish systemic trophies while skipping half the roster above. Use this page as a living checklist beside Achievements.

Pacing tips

Do not open every door the moment you hold a key if three halls already sit at 60%. Depth beats breadth for cozy satisfaction and for XP efficiency. When you do open a room, run the five-step approach at the top before bouncing elsewhere.

Final curator note

The grand opening fantasy only works if every listed wing could welcome a visitor. Tidy Up History on Windows Steam is single-player — you are facilities, registrar, paleontologist, and director. This roster is your org chart of spaces. Restore them with equal respect, from Cerapoda to Indigenous North America, and the museum earns its name again.
