Key takeaways
- Push order — which block you commit first, because the first push often eliminates the option to move the other block past it.
- Portal sequencing — using a portal before or after a block clears the mouth, never during.
- Anchor points — walls and fixed pillars that a pushed block will stop against; these are free brakes, not obstacles.
- Reserve space — leaving one empty tile beside every block you plan to reposition more than once.
HSR Janus Maze Solutions: Complete Guide
The Janus Maze in Honkai: Star Rail is a rotating puzzle activity built around portals, blocks, and traversal nodes, and the fastest way through it is to follow the short checkpointed routes below: clear each room in order, walk through free-standing portals rather than trying to push blocks through gaps, and reset the room immediately if a movable block ends up against a wall you still need. Every section here is reversible — the activity lets you restart a single chamber without losing progress on the ones you have already cleared.
This guide covers the full route logic for each Janus Maze section, the exact order of operations that stops you from soft-locking a chamber, and the reset rules for when a puzzle does wedge itself. Route names below describe the puzzle layout rather than any single patch’s naming convention, since the activity has been reissued across versions.
How the Janus Maze Works
Each Janus Maze chamber is a small grid containing three interacting pieces: a pawn node (the character or device you are moving), one or more free portals that teleport whatever enters them to a paired exit, and pushable blocks that slide in a straight line until something stops them. The whole system is deterministic, which is both the good news and the trap: nothing is random, so a chamber is always solvable, but any block you push into a corner stays there until you reset.
The rule that trips up most players is that portals and blocks handle differently. A pushable block that enters a portal does not travel through it — it stops at the portal’s mouth and the portal becomes unusable from that side. Your pawn node passes through freely. So the order in which you move blocks relative to portals is the single most important variable in every chamber, and it is why a “wrong” route usually looks correct right up until the last move.
The four things every chamber tests
- Push order — which block you commit first, because the first push often eliminates the option to move the other block past it.
- Portal sequencing — using a portal before or after a block clears the mouth, never during.
- Anchor points — walls and fixed pillars that a pushed block will stop against; these are free brakes, not obstacles.
- Reserve space — leaving one empty tile beside every block you plan to reposition more than once.
Quick reference: chamber type, key move, and reset risk
| Chamber type | Pieces to move | Key first move | Typical reset risk | Approx. time when solved cleanly |
|---|---|---|---|---|
| Single-portal corridor | 1 block | Push block away from portal mouth first | Low — only one dead-end | 30–60 seconds |
| Twin-portal room | 2 blocks, 2 portals | Clear both mouths, then route the pawn | Medium — blocks can seal each other | 1–2 minutes |
| Anchor-grid chamber | 2–3 blocks, 1 portal | Use the far wall as a stop for the longest push | High — corner trapping is common | 2–3 minutes |
| Loop chamber | 1 block, chained portals | Identify which portal is the exit, not the entry | High — misinformation from the loop itself | 2–4 minutes |
| Multi-stage relay | 3+ blocks, overlapping portals | Work backwards from the goal tile | Very high — mistakes compound across stages | 4–8 minutes |
The time estimates assume you already know the chamber type. On a first blind run, expect roughly three times those figures, because the discovery phase is where the resets happen.
Route Solutions, Section by Section
The route logic below is written as an ordered sequence of moves, because Janus Maze chambers are order-sensitive — a “correct” move made in the wrong position in the sequence produces a soft-lock. Read the whole sequence before you touch anything.
Section 1: Single-portal corridor
Route: Enter the chamber and identify the portal’s paired exit before moving. Push the single block one tile along the axis perpendicular to the portal mouth — this parks it against the chamber wall and opens the mouth permanently. Then walk the pawn node straight through the portal and into the goal tile.
Why it works: the block’s only failure state is sitting on the portal mouth, which blocks passage for your pawn. Pushing it perpendicular guarantees it lands against a wall, and a block against a wall can never drift back over the mouth.
Checkpoint: after the push, the portal should be visibly unobstructed and the block flush with a wall. If the block sits one tile off the wall, you pushed the wrong direction — reset and re-read the room.
Section 2: Twin-portal room
Route: Clear block A from the nearer portal mouth first, pushing it away from block B. Then clear block B from the second mouth, pushing it toward the wall you just anchored block A against. Only once both mouths are clear do you send the pawn through the first portal, exit at the paired point, and cross to the goal.
Why it works: the two blocks can seal each other if you clear them in the opposite order, because the space you need to stand in to push B is the same tile block A wants to occupy. Clearing A first keeps that standing tile free.
Checkpoint: both blocks should be on the same side of the room, at least two tiles from either portal mouth. If one block is within one tile of a mouth, stop and reconsider before pushing anything else.
Section 3: Anchor-grid chamber
Route: This is the chamber where you use the walls as tools. Identify the longest continuous push available — usually a three-tile slide along the outer wall. Push the longest-slide block first, using the far wall as a hard stop so it lands exactly where the next stage needs it. Then handle the remaining two blocks in order of distance from the goal tile: farthest first.
Why it works: a block pushed into a wall cannot overshoot, which converts an uncertain move into an exact one. Players who push the short-distance blocks first typically run out of standing room for the long push and have to reset.
Checkpoint: before the final move, there should be exactly one empty tile between the goal tile and the last block you intend to move. No tile of slack means your earlier pushes were one step too aggressive.
Section 4: Loop chamber
Route: The loop chamber contains two portals that feed into each other, which makes the visible exit misleading. Trace the chain mentally before moving: portal 1 exits at portal 2’s location, and portal 2 exits at portal 1’s location — so entering either one returns you to the other side of the room, not forward. The actual exit is the third, unpaired portal near the goal tile. Push the single block off that third portal’s mouth, then walk through the loop portals deliberately to reach it.
Why it works: the loop is a transit system, not a dead end. It exists to move your pawn across the room without crossing the block’s push lane.
Checkpoint: count the portals before you start. If you can only find two, you are in a different chamber type than you think, and the route above does not apply.
Section 5: Multi-stage relay
Route: Work backwards. Start at the goal tile and ask which piece must be adjacent to it on the final move. That piece’s staging tile tells you which block has to move out of the way, which tells you the first push. In practice this inverts the “obvious” opening move roughly half the time.
Why it works: in a three-stage relay, an early mistake is invisible for two full stages and then becomes permanent. Backwards planning front-loads the constraint instead of discovering it at the end.
Checkpoint: after stage one, the second stage’s push lane should be completely clear of other blocks. If it is not, the first push was wrong even though the stage-one goal is technically met.
Reset Rules and Recovery
Resetting is not a failure state in the Janus Maze — it is one of the mechanics. The activity resets a single chamber without touching clearance on any chamber before it, so a mid-run reset costs you the time in that room and nothing else.
When to reset immediately
- A block is in a corner you did not intend. Corners are two-walled anchors; a block there needs two separate pushes to move and a three-wide channel to do it, which most chambers do not have.
- A block is sitting on a portal mouth with no perpendicular push available. The mouth is sealed for your pawn and the block cannot be moved sideways.
- You have no empty tile adjacent to a block you still need to move. Without standing room, the push does not exist.
- You have made more than six moves without clearing a stated checkpoint. Past that point in a small chamber, the probability that the position is still good is low enough that a reset is faster than further diagnosis.
When not to reset
If a block is against a single wall, mid-chamber, with an open lane behind it, the position is almost certainly still solvable. Walls are the cheapest thing to push off, so a wall-anchored block is a held resource, not a mistake. Resetting here usually just repeats the same moves.
Common Mistakes That Cause Soft-Locks
- Pushing before scouting. Walking the perimeter once before the first push prevents most resets. It costs ten seconds and saves a minute.
- Treating paired portals as one-way. In most chambers they are bidirectional, and re-entering without a plan puts you back where you started.
- Using the nearest block first. Distance from the pawn is irrelevant; distance from the goal tile is what determines push order.
- Forgetting that a block on a portal mouth disables that portal. This is the single most common cause of an otherwise inexplicable dead end.
- Rushing the multi-stage relay. Chambers with three or more blocks punish speed harder than any other type because errors are silent for stages at a time.
Frequently Asked Questions
Do I lose progress if I reset a Janus Maze chamber?
No. The reset applies to the chamber you are currently in and leaves previously cleared chambers completed. You return to the start of that one room with all pieces in their original positions. The only cost is the time already spent in the room.
Why does my block stop moving when I push it into a portal?
Pushing a block into a portal stops it at the portal’s mouth rather than sending it through — only your pawn node travels through portals. That also disables the portal from that side, so the standard fix is to push the block perpendicular to the mouth and park it against a wall instead.
What is the correct order for a two-portal chamber?
Clear block A from the nearer mouth first, pushing away from block B, then clear block B and anchor it against the wall you used for A. Clearing them the other way seals B, because the tile you need to stand on to push B is the tile block A wants.
How do I tell a loop chamber from a normal twin-portal room?
Count the portals before moving. A loop chamber has two portals wired to each other plus a third unpaired portal near the goal tile; a twin-portal room has exactly two portals, each exiting at a fixed point. If there are only two portals, you are in the simpler room type.
How long does the full Janus Maze take?
Cleared cleanly, the five chamber types in this guide run roughly 30 seconds to 8 minutes each, with the single-portal corridor at the fast end and the multi-stage relay at the slow end. A first blind run typically takes about three times those figures because of discovery resets.
Is there a way to solve multi-stage relay chambers without trial and error?
Yes — plan backwards from the goal tile. Identify which piece must be adjacent to the goal on the final move, then which staging tile that piece needs, then which block must clear out of the way to allow it. This front-loads the constraint that would otherwise only become visible two stages later.
