A DOOR, NINE PUZZLES, YOUR CHOICE OF SPOILERS
MONOMOON Red Temple puzzle solutions
Reach the entrance, decode the door, and solve all nine panels.
The Red Temple tests several different rules: counting lines, finding digits inside shapes, combining segments, and reusing earlier answers. Select a puzzle below to see its hint, then open the answer only when you want the code. The entrance route and every solution are included on this page; you do not need to leave the site to finish this area.
Community-documented solutions checked November 14, 2026. Not a claim of our own playthrough. Puzzle numbering follows the sequence below.
How to reach the Red Temple entrance
The entrance sits at map cell (15,08), near the bottom-center of the world. Before attempting the route, you need to be able to reach the starting cell (13,07) and teleport to the save point at (13,05). If these numbers are unfamiliar, use our MONOMOON number symbols and map instructions first. X counts from the left and Y counts from the bottom.
- At (13,07), find the lift entrance. The other entrance is button-blocked; this route uses the lift instead.
- Activate the lift fully using the relevant left-mouse-button interaction.
- Quickly teleport to the save point at (13,05).
- Move up one screen and board the lift before it departs.
- Ride it to reach the Red Temple approach, then examine the entrance door.
The key is changing how you reach the lift after activating it. You do not need to walk the entire way while continuing to hold the mouse button. If the timing fails, return to the starting setup and repeat the activation and teleport sequence. The coordinate reference identifies screens; it does not imply that you can move directly through every intervening wall.
Open the Red Temple symbol door
The wheel uses number symbols. Arrange them in ascending order, 0 through 9 clockwise, using the dot counts as your reference. This is a sequence around the wheel, not a three-digit code like several of the panels inside.
Use the number-shape chart if you cannot yet distinguish the digits. Match the entire symbol before rotating it into position: a top bar and a bottom bar are not interchangeable. Once the numerical order is correct, the Red Temple door opens. The panel guides below assume that you have passed this door.
Red Temple puzzle 1: horizontal lines
Hint: Treat the three figures separately. The chalk clue associates one horizontal line with the value one; it is not asking you to count every segment regardless of direction.
Reveal puzzle 1 method and code
Count only the horizontal strokes in each figure, then enter the three totals in figure order. Vertical and diagonal strokes do not contribute under this rule. The Red Temple code is 503. The zero in the middle is a real digit: retain it rather than shortening the answer to 53.
Red Temple puzzle 2: turns between circles
Hint: Compare the chalk example's zero with the paths in the puzzle. Count what changes along the connecting path, rather than the circular endpoints.
Reveal puzzle 2 method and code
Follow the lines between circles and count their twists or turns. Counting circles gives the wrong quantity. Enter 12 for this Red Temple panel. Keep this rule separate from the previous puzzle's horizontal-line count: the visual clues establish a new operation, even though the input still uses number symbols.
Red Temple puzzle 3: intersecting lines
Hint: Inspect the input buttons as well as the figures. The chalk example indicates two intersections, and the partially shown second figure should be considered symmetrical.
Reveal puzzle 3 method and code
Count the intersecting lines in the figures. The documented result is six for the first figure and sixteen for the second, using its symmetry: eight doubled gives sixteen. Enter 616. Do not reinterpret that as three independent figure totals of six, one, and six. This Red Temple puzzle is why the number of buttons alone is not a reliable guide to how many separate quantities you are counting.
Red Temple puzzle 4: digits inside squares
Hint: Compare the four square-based figures with the number symbols you learned at the entrance. Look for recognizable digits embedded in the surrounding lines.
Reveal puzzle 4 method and code
Identify the hidden digit in each figure and preserve their order. The Red Temple answer is 5297. This time you are recognizing shapes, not totaling intersections or horizontal strokes. Keep a record of this code: the final puzzle refers back to this panel along with two neighboring puzzles.
Red Temple puzzle 5: exclusive-or segments
Hint: Each column combines a pair of symbols. Ask which line segments belong to only one member of the pair, rather than which appear in both.
Reveal puzzle 5 method and code
Compare corresponding segments. Keep a segment when it occurs in exactly one symbol; remove it when both contain it. This exclusive-or, or XOR, operation produces the digits 357. Work column by column so that lines from different pairs do not get mixed together. Save this Red Temple answer for the last panel.
| First symbol | Second symbol | Result |
|---|---|---|
| Absent | Absent | Absent |
| Present | Absent | Keep |
| Absent | Present | Keep |
| Present | Present | Remove |
Red Temple puzzle 6: the incomplete mural
Hint: You do not need to recover the missing piece. Return to the hidden-number idea from puzzle 4 and use the surviving parts of the figures.
Reveal puzzle 6 method and code
Find the digits embedded in the square-based shapes. The remaining information gives 64. A damaged mural does not automatically mean you are missing an inventory item. Record this Red Temple code with 5297 and 357; these three answers are the references needed at the final puzzle.
Red Temple puzzle 7: overlapping symbols and light
Hint: Shine light on the wall before interpreting the figure. The highlighted lines and the three side buttons help identify both the symbols and their input positions.
Reveal puzzle 7 method and code
Find three number symbols whose combined lines reproduce the original figure. Each must use a highlighted line, and those lines indicate the corresponding digit positions. Do not simply read the highlights from top to bottom: the top line points to the second digit. The Red Temple code is 523.
Red Temple puzzle 8: dots in triangular cells
Hint: Illuminate the wall and compare the cells containing one dot with those containing two. The incomplete third figure can be solved without finding its missing fragment.
Reveal puzzle 8 method and code
Imagine a number symbol drawn inside each grid. The dots describe how many of its lines border each triangular cell. Find the digit matching those local counts and repeat for the other figures. Enter 097, including the leading zero. This Red Temple answer has three positions; entering only 97 omits the first one.
Red Temple puzzle 9: reuse earlier answers
Hint: Shine light on the wall, inspect the input buttons, and compare the small rectangles with room shapes on your map. The large blank squares refer to earlier puzzles.
Reveal puzzle 9 references and code
The references are puzzles 4, 5, and 6 on the second floor. Their answers are 5297, 357, and 64. The final Red Temple panel uses selected digits from those answers, rather than asking you to concatenate all three codes. Enter 9374. The earlier solutions remain available above if you skipped taking notes or need to recheck a digit.

If a code does not match the panel you are facing, compare its visual rule with the descriptions above. Our numbering describes this guide's sequence, so identify the figure before applying an answer. Keep leading zeros and enter digits in the stated order.
