Timing note: This guide is being published on October 7, 2026, one day before the planned October 8 release. The full game is not yet available on Steam, so verified advice about its hardest full-game puzzles and their solutions is not available yet. For now, use a spoiler-aware method to reason through unfamiliar rooms; the walkthrough information currently available applies to the demo only.
What is known about the puzzles so far?
Thekla describes Order of the Sinking Star as having more than 1,000 interconnected, handcrafted puzzles. Its Steam description presents four distinct worlds, each with its own mechanics, characters, and stories, and says their puzzle systems intertwine as the worlds merge. It also explains that puzzles build on one another, introducing mechanics that reward curiosity and persistence.
That structure suggests a useful way to approach a difficult room: first understand the rule in front of you, then consider whether the room changes or combines it with something learned elsewhere. It does not establish which puzzles are hardest or provide verified solutions for the full game.
A spoiler-aware method for getting unstuck
The following is general reasoning guidance based on the game’s official description, not tested gameplay or a set of verified full-game solutions. Work through the steps in order, and stop once you have a useful new idea.

#1 Best Overall
- State the immediate goal. Identify what needs to change for the puzzle to progress. Note the objects, characters, or mechanisms that appear able to affect that outcome.
- Recall the most recently introduced mechanic. Ask what the current area has taught you, then check whether this room uses that rule unchanged, varies it, or pairs it with another system.
- Test one assumption at a time. Make a small change and watch what responds. Changing several things together can make it harder to tell which rule you have learned.
- Ask for a nudge before a move sequence. A good first hint names a relevant mechanic or relationship without solving the room for you.
- Escalate only if needed. If the nudge does not help, seek a partial hint, then a complete solution. Prefer help labeled for the specific demo room when relying on currently verified walkthrough material.
Choose the right level of help
An independent, fan-made walkthrough for the demo uses three levels of disclosure. Treat them as a practical spoiler ladder, not as an official hint system for the full release.
| Help level | What to look for | When to stop |
|---|---|---|
| Nudge | A clue about a mechanic, object, or relationship to reconsider. | Stop here if it gives you a new experiment to try. |
| Partial hint | A more specific pointer that narrows the next action without laying out the whole solution. | Stop here if you can now work out the sequence yourself. |
| Full answer | The complete solution for the named puzzle. | Use it when preserving the discovery matters less than moving on. |
The walkthrough is unofficial and demo-specific; it cannot establish answers for full-release puzzles. Its author reports more than 100 demo puzzles across three explorable worlds and a hub, but that is the walkthrough’s account, not an official statistic for the game.

How to use demo walkthroughs without confusing their scope
Check that a solution names the demo room you are playing before following it. A hint for a different room—or for a later combination of mechanics—may not apply. The fan-made Order of the Sinking Star Wiki walkthrough is the available guide covered here; it should be treated as a source of demo help, not as an authoritative ranking of the full game’s hardest puzzles.
The release is planned for October 8, 2026, according to Thekla’s official site and the Steam listing, which showed the game as not yet available when checked on October 7. Until full-game information can be verified, no particular puzzle should be labeled the hardest or assigned a definitive solution.
