The Order of the Sinking Star guide you are about to read consolidates everything we know about Jonathan Blow’s massive puzzle adventure, from the four colliding worlds to the hidden mechanics that most players miss on their first pass. Whether you are looking for a full walkthrough, practical tips, or a community-driven wiki-style reference, this page is built to save you hours of trial and error. Since the game launches on October 8, 2026, across PC, Steam Deck, Nintendo Switch 2, and PlayStation 5, having a solid foundation before you dive in matters more than you might think. This guide will help you understand the core systems, avoid common early mistakes, and approach each world with a clear strategy.
Understanding the Core Puzzle Mechanics
Mirror the Undo and Push Vector in the Mirror Isles
In the Mirror Isles, the undo system has no limit, but every undo flips the mirror, reversing the direction of your next push. This makes undoing a dangerous tool: to correct a misaligned block, you must undo, then push in the opposite direction. Compare to the first world, where undos are capped at 3 and have no side effects. A typical Mirror Isles solve requires 5–7 undos, but each undo changes the push vector, so you must re-evaluate the entire board after every rewind. Use the undo to test a push, then undo it to apply the mirrored correction.
Before diving into the mechanics, here is a quick snapshot of what players have been searching for most around the game's demo and launch window.

The heart of the Order of the Sinking Star guide lies in understanding how the game blends Sokoban-style block pushing with environmental observation puzzles that recall the best moments of The Witness. Jonathan Blow’s design philosophy here is that every rule is taught through play, so the game never explicitly tells you the rules, but the world itself communicates them through patterns, lighting, and geometry. The four worlds—Mirror Isles, The Sunken Archive, The Observatory, and The Drowned City—each introduce a distinct mechanic that then combines with the others in later puzzles.
The most important early concept is Casting Distance, which determines how far your character can project a light beam across gaps. This beam is not just for illumination; it activates Tidal Gates, which are the primary door-opening mechanism in the first two worlds. The beam also reveals Echo Stones, hidden collectibles that unlock lore entries in your journal. According to the official Order of the Sinking Star website, the game features over 200 puzzles across all four worlds, and the demo alone contains roughly 15 of them, which gives you a sense of the scale.
| Core Mechanic | Primary Function | First Introduced | Difficulty Curve |
|---|---|---|---|
| Casting Distance | Projects light to activate gates and reveal hidden paths | Mirror Isles | Low, but scales with world complexity |
| Sokoban Block Pushing | Move blocks to create platforms or redirect beams | Sunken Archive | Medium, requires spatial planning |
| Chrono Tides | Reverses water flow and alters gravity zones | The Observatory | High, requires timing and sequencing |
| World Collision | Overlaps two worlds to create hybrid puzzle spaces | Hollow City | Very High, combines all prior mechanics |
Because the game uses a non-linear world order, you can tackle the first three worlds in any sequence, though the fourth world only unlocks after you have completed at least two of the others. This design choice means that your Order of the Sinking Star walkthrough experience will vary depending on which world you choose first, which is a deliberate nod to the game’s theme of colliding realities.
Essential Tips for Your First Playthrough
If you are looking for Order of the Sinking Star tips that actually move the needle, the most valuable advice is to treat every environment as a tutorial. The game rewards careful observation over brute-force trial and error, and players who rush through the first area often miss the Far Water region, which is an optional but highly rewarding sub-area that teaches the Chrono Tides mechanic early. According to player reports, the demo’s most common complaint is that players did not realize they could interact with the Sunken Bell in the Mirror Isles, which is the key to unlocking the hidden ending.
The hint system is another underrated tool. If you are stuck for more than five minutes, the game will subtly shift the camera angle to point you toward the solution, but this only works if you are standing still. Moving around too much resets the hint timer, so the best strategy is to stop, observe, and let the game guide you. This is a design choice that rewards patience, and it is one of the reasons the game has been compared to the best puzzle titles of the last decade.
The Mirror Isles Walkthrough Essentials
The Mirror Isles is the most commonly recommended starting world because its mechanics are the most intuitive. The world is built around reflection puzzles, where you must align mirrors to bounce light beams across the map. The key is to remember that your character’s reflection in the water is not just cosmetic; it can interact with certain objects that your physical body cannot. This means you will often need to position your body in one place while watching your reflection perform an action in another.
The Tidal Gates in this world are the main progression blockers, and they require you to find the correct Anchor Points to raise the water level. Each gate has three anchor points, and you must activate them in a specific order, which is usually indicated by the size of the ripples in the water. The community wiki has documented that the order is always from smallest ripple to largest ripple, which is a subtle hint that many players miss. Once you understand this pattern, the Mirror Isles become significantly easier, and you can complete the world in about three to four hours.
Advanced Strategies for the Later Worlds
Once you have mastered the basics, the Order of the Sinking Star guide shifts to the more complex interactions between worlds. The The Observatory is widely considered the most challenging world because it introduces gravity manipulation, which means you can rotate the entire room to change the direction of the puzzle. This is where the Sokoban mechanics become truly demanding, because you must push blocks into positions that work in both the normal and rotated orientations.
The Chrono Tides mechanic in the Observatory is the most complex system in the game, and it requires you to record a sequence of actions and then replay them in reverse. This is a puzzle mechanic that rewards careful planning, and it is the main reason why the game is often compared to Braid. The key tip here is to always record your actions in short segments, because the game only allows you to rewind a maximum of ten seconds of recorded time. If you try to record a longer sequence, the game will automatically cut the recording, which can break your puzzle solution.
The Hollow City and Final Puzzles
The Hollow City is the final world, and it combines all the mechanics from the previous worlds in a single, massive puzzle space. The world is designed as a vertical labyrinth, and you must use the Casting Distance from the first world, the block pushing from the second, and the gravity manipulation from the third to navigate the city’s multi-level structures. The final puzzle of the game is a meta-puzzle that requires you to solve a series of smaller puzzles in a specific order, and the solution is not immediately obvious. According to community testing, the final puzzle takes an average of 45 minutes to solve, and it is the most satisfying moment in the game.
The Best Order to Tackle the Four Worlds
Since the game allows you to choose your path, the order in which you tackle the worlds significantly affects your experience. Based on community data and the official Steam page, the recommended order is Mirror Isles first, then the Sunken Archive, followed by the Observatory, and finally the Hollow City. This order is optimal because it introduces mechanics in a logical progression, and it ensures that you have the necessary tools to solve the later puzzles without backtracking.
| World | Recommended Order | Difficulty | Time to Complete | Key Reward |
|---|---|---|---|---|
| Mirror Isles | 1st | Beginner | 3-4 hours | Echo Paths (lore) |
| The Sunken Archive | 2nd | Intermediate | 4-5 hours | Chrono Tides (mechanic) |
| The Observatory | 3rd | Advanced | 5-6 hours | Gravity Core (mechanic) |
| The Hollow City | 4th | Expert | 6-8 hours | True Ending |
The Echo Paths you unlock in the Mirror Isles are not just collectibles; they are the key to the game’s true ending. If you collect all of them, you unlock a final cutscene that explains the origin of the four worlds and the reason they are colliding. This is a significant incentive for completionists, and it is one of the reasons why the game has a high replay value. If you are aiming for the 100% completion, you should follow the completion guide which details every collectible and hidden puzzle.
How Long Does It Take to Beat the Game?
The total playtime for the Order of the Sinking Star depends on your puzzle-solving skill and whether you are aiming for the true ending. Based on community reports, a standard playthrough takes between 15 and 20 hours, while a completionist run can take up to 30 hours. The demo, which was released earlier, contains about 15 puzzles and takes approximately 2 hours to complete, which is a good indicator of the game’s pacing. The game also features a New Game Plus mode, which re-mixes the puzzle solutions, so even a second playthrough will feel fresh.
