Red Temple Puzzle Solutions & Codes

The MONOMOON red temple sits near the bottom center of the map, and its nine puzzle rooms stop more players than any other area in the game. If you are staring at a wheel of unfamiliar symbols or a wall of chalk drawings with no idea what to count, you are not alone — and you do not need a guide open on a second screen to finish it. This MONOMOON red temple walkthrough gives you the entrance route, the exact code for all nine rooms, and the reasoning behind each answer so you can check your own reading instead of blindly copying digits.

The Red Temple — also called the Red Door area — is optional-feeling but central to progression. The game is a Metroidbrainia: it hands you no instructions, and every clue lives somewhere inside the world. Some rooms here require knowledge you pick up elsewhere, so a code you cannot decode today may click after one more Tome page.

Finding the Red Temple and Opening the Door

The temple outline is visible near coordinates (15,08) at the bottom center of the map, long before you can get inside. The entrance puzzle starts from (13,07).

Two routes present themselves: one is blocked by a button and looks like a shortcut, while the other involves a lift you can send down. The real question is where that lift travels and whether you can reach the landing point while keeping your left mouse button held.

Entrance Steps

The trick most players miss is releasing LMB rather than trying to hold it across the whole sequence. Once the lift is running, fast travel does the work: warp to the save point, step up one screen, and hop on before the platform leaves.

At the front door you meet a wheel covered in symbols. If the number system still looks like nonsense, leave and come back later — the door is a reading test, not a dexterity test.

Door Solution

Rotate the wheel until the symbols sit in clockwise order from 0 to 9. Count the dots on each symbol to identify which digit it represents. The door opens on the correct sequence, and you are into the first chamber.

Number Symbols: The Skill Behind Every Red Temple Code

Almost every MONOMOON red temple puzzle is secretly a number puzzle. The game uses ten symbols for the digits 0–9, and every number is written with two symbols — tens first, units second. That single rule explains why some answers look like three digits and others like two.

If you want a dedicated refresher on reading the digits and how tens and units combine, the breakdown of map coordinates and number symbols covers the full set. Practicing on coordinates is the fastest way to internalize the symbols, because you read them constantly while exploring.

All Nine Red Temple Puzzle Codes

Below are the answers in the order you encounter them, with the logic that produces each one. Use the hint column first if you want to solve it yourself.

Puzzle 1: Count the Lines

Treat the combination as three separate digits, not one big number. The chalk drawing tells you each horizontal line is worth 1, so tally the horizontal strokes in each figure. That gives 5, 0, and 3.

Puzzle 2: Measure the Gaps

Do not count circles. The chalk drawing shows a value of 0, which is your warning that quantity is irrelevant. Instead compare the horizontal positions of the circles and add the gaps: 1 + 2 + 2 + 1 + 2 + 2 + 2 = 12.

Puzzle 3: Intersections and Symmetry

Inspect the three buttons for anything unusual, then count intersecting lines in each figure. The first gives 6. The second is symmetrical, so its 8 lines double to 16 — entered as the two digits 1 and 6. The code is 616.

Puzzle 4: Numbers Hiding in Plain Sight

Four figures, four buttons, four digits. Each design conceals a numeral inside its square. Identify the embedded number in each and enter them in order for 5297.

Puzzle 5: The XOR Trick

Draw each pair of symbols side by side, then separate shared segments from unshared ones. Keep only the segments that appear in one symbol but not the other — an XOR operation. Each of the three columns yields one digit, producing 357.

Puzzle 6: Same Method, Missing Mural

Part of the wall is gone, and you do not need it. This room repeats the hidden-number logic from Puzzle 4, so read the embedded numerals in the figures you can see. The answer is 64.

Puzzle 7: Overlapping Symbols

Shine your light on the wall first. Three number symbols overlap to form the figure, and the highlighted lines tell you which digit each corresponds to — the top line, for instance, belongs to the second digit. Find three symbols whose combined lines recreate the drawing and order them by those highlights: 523.

Puzzle 8: Dots and Adjacent Lines

Light the wall, then look at the triangular cells. A cell with one dot touches one line of a number symbol; two dots means two lines. The missing piece of the third figure is not required. Match dot counts to line placements to identify 0, 9, and 7.

Puzzle 9: Callback Room

This one breaks the pattern. Light the wall, study the buttons closely, and examine the three small rectangles of different widths that respond to your Moon — their shapes echo something else in the room. Open your map and look for a matching arrangement. The three large empty squares stand for puzzles you already solved: Puzzles 4, 5, and 6 on the second floor. Combine their correct digits in the required order and you get 9374.

For room-by-room verification of every chamber, the full set of Red Door answers is worth keeping handy while you work.

Practical Tips Before You Enter

• Learn the digits first. The door is unsolvable without them, and every interior puzzle builds on the same ten symbols.
• Light every wall. Puzzles 7, 8, and 9 hide critical information until you shine light on the surface.
• Read the chalk drawings as rules, not decoration. Each one hands you a value — 0, 1, or 2 — that tells you what to count or ignore.
• Trust symmetry. Puzzle 3 explicitly rewards assuming the second figure mirrors itself.
• Do not hunt for the missing mural piece in Puzzle 6. It is not needed.
• Revisit later if a room stalls. Some chambers need knowledge from elsewhere in the world; exploring another area often makes the answer obvious.
• Check inactive checkpoints and unexplored openings when you feel stuck between rooms. Progression is nonlinear, so a blocked puzzle is sometimes a signal to leave.

Frequently Asked Questions

Can I finish the MONOMOON red temple without learning the number symbols? No. The entrance door requires you to arrange the ten symbols in clockwise order from 0 to 9, and Puzzles 1, 4, 6, 7, and 8 all depend on reading digits. Learn the symbols through map coordinates first — it is the least painful route.

How long does the Red Temple take? The main game runs about 10 hours, and the temple is one concentrated slice of that. Most of your time goes into the door and the first few rooms while you are still learning the number system; later puzzles fall faster once the logic clicks.

What is the hardest puzzle in the Red Temple? Puzzle 9 tends to stall players because it abandons the standalone-number format entirely. It points back to Puzzles 4, 5, and 6, so keep those three codes written down. Puzzle 5 is the other common wall, since XOR on symbol segments is not a technique the game teaches explicitly.

Do I need external tools to solve these? Every MONOMOON red temple puzzle is solvable solo, and all clues exist inside the game. Treat any code list as a cross-check for your own reading rather than a replacement for it — the same symbol logic returns in later areas and in the elevator puzzle, where each elevator room's vertical coordinate goes into two grids.

Once the nine rooms are cleared, the temple stops being a wall and becomes a reference point: the number symbols you learned here make the map, the elevators, and the late-game coordinate puzzles far easier to read.
