Quick answer
Tidy Up History has 25 Steam achievements, confirmed by the official Steam information recorded in the project brief. The collected gameplay also confirms that achievements can unlock for first-time restoration actions, collecting all Knowledge Books, assembling a complete dinosaur, completing rooms, and fully restoring the museum. However, the current project files do not contain a verified official list with every exact name and condition. This guide therefore organizes an achievement-safe route around confirmed systems and marks the complete title-by-title table as awaiting confirmation rather than guessing hidden requirements. For the cleanest run, complete every room system, keep the game updated, and avoid recovery cheats until you know whether they affect your version's achievement behavior.
What is confirmed
The official total is 25 achievements. Gameplay in the research shows notifications tied to placing an artifact, placing or assembling fossil content, performing repairs, completing knowledge collection, finishing a dinosaur skeleton, restoring individual rooms, and reaching full museum restoration. These observations establish broad categories, but a video caption or spoken paraphrase is not enough to publish an exact Steam title as fact.
Until the current official achievement list is captured in the project research, exact names, descriptions, hidden status, and per-room counts remain to be confirmed. This boundary prevents a plausible-sounding checklist from sending players toward conditions that do not exist. Use Steam's own achievement panel for the precise title visible in your account.
- Confirmed total: 25 Steam achievements.
- Confirmed category: early placement and restoration actions.
- Confirmed category: Knowledge Book collection.
- Confirmed category: complete dinosaur assembly.
- Confirmed category: room and full-museum restoration.
- Exact official title-by-title conditions: to be confirmed from Steam.
Prepare an achievement-safe playthrough
Update the game before beginning a completion-focused save. The project material includes patch notes and player reports about achievements not unlocking on some systems, including Windows reports after earlier save issues. Those reports do not mean the problem affects every player, but they make version checking and save protection important.
Use normal progression when possible. Clean, repair, place artifacts, read books, assemble fossils, apply labels, and open rooms through found keys. The built-in codes 21122124 and 42144432 can recover Level Up or the Egypt Key, but the research does not confirm achievement behavior after every cheat-assisted route. Keep an unaffected save before testing them.
Capture early action achievements naturally
Do not rush past the first gallery while carrying every object elsewhere. Perform at least one confirmed example of each core action as it becomes available: place an identified artifact, attach a fossil piece, complete a repair, remove available dirt or webbing, and interact with the progression systems. Collected footage shows achievement notifications during these basic milestones.
Because the exact official names are not yet verified in the files, this guide avoids mapping each action to a fabricated title. Instead, watch the Steam overlay or achievement panel after the first successful action. If a clearly completed milestone does not register, stop before investing hours in a broken run and consult official discussions.
Cover collection and exhibit milestones
Knowledge Books, artifacts, labels, and fossils should be treated as separate audit categories. Gameplay confirms a milestone when all books were collected, while artifact and label work contributes to room completion. Dinosaur assembly has its own confirmed achievement behavior. Keep a manual room record so one missing system does not hide behind an apparently tidy exhibit.
For each open gallery, record condition work, knowledge, artifacts, labels, and special fossil assembly. Do not enter a guessed collectible total. A checklist based on room state is safer because it relies on what the game visibly confirms. When every accessible room is complete but an achievement remains locked, compare the Steam description with your record rather than repeating random actions.
Handle room and museum completion
A room can require more than object placement. Recheck dirt, water, cobwebs, walls, floors, lights, display slots, labels, and any special exhibit assembly. Later abilities can reveal or enable work missed in the opening hours. Use a final perimeter pass and the game's helping features only after completing the normal visual inspection.
Full museum restoration should be attempted after every key-accessible wing has been opened and every system has been audited. Collected footage confirms a final restoration milestone, but the precise trigger should be read from the current Steam achievement description once captured. Avoid claiming that a single percentage, cutscene, or room count is universally sufficient.
Troubleshoot an achievement that does not unlock
First confirm that Steam is online, the overlay recognizes the running game, and the achievement is still locked in the official panel. Re-enter the relevant room, verify its condition and displays, and allow the game to save. Do not repeatedly use a guessed trigger. If a milestone is clearly complete, note the game version, operating system, save history, and exact action that failed.
Check official Steam discussions for current developer guidance and patch notes. The research contains reports of achievement problems on Windows and earlier save-related behavior, so a reproducible report is more useful than speculation. Back up the save before retesting. This site does not promise an unsupported console command or file edit.
Final 25-achievement audit
When the official panel shows only a few locked entries, sort them by the wording Steam provides: action, collection, room, fossil, or museum completion. Match that category to the corresponding guide and verify its visible game state. This narrows the search without inventing secret conditions.
The full title list and any hidden descriptions remain to be confirmed from an authoritative capture. Until then, the responsible completion route is to finish every documented museum system and troubleshoot only against Steam's live achievement text. Use the 100% guide as the cross-system checklist and the walkthrough to revisit progression in order.
