MONOMOON Puzzles

Count four-way crossings

The line board wants a count of crossings, not a vibe about “how busy” the drawing is. A crossing counts when four line ends meet. Include joints that are skewed, thick, or not a textbook X. A T-junction has three ends and is a different shape — do not fold those into the four-way total unless the page in your Tome says the rule is wider.

Two community totals, 6 and 16, are both in circulation. Both are Unverified. They come from people counting different joints. Mark every four-way meet on your own door, once, and use that count. If your count matches neither rumor, keep yours.

Pair the symbols

Another board shows a mark above a mark, sometimes beside a familiar digit such as 0, 1, or 2. Read the column as a pair. The top symbol and the bottom symbol combine. Players have mistaken one mark for an equals sign. Which mark that was is Unverified. Treat a familiar-looking operator as its own symbol until the Tome shows it.

Write the pair, then the digit it sits with. Entering the first number you recognize, alone, drops the operator. The page that teaches the combination is the book from the opening room. The first page is symbols in a script you do not know yet — that script is the key, not flavor.

Test one segment

A later panel looks like a digit built from strokes, close to a seven-segment figure. A dot sits on one stroke. The question is only whether that stroke exists on the digit you are testing. Positions are the usual seven: top, upper left, upper right, middle, lower left, lower right, bottom.

A digit drawn with all seven strokes answers present for any dot. A digit drawn with only two strokes on one side answers absent for the top bar. Those are examples of the rule, not a code. You answer present or absent per dot, on your panel. A finished digit string from outside your save is Unverified, even when the segment rule is the right method.

Read triangles like mines

The triangle board behaves like a mines grid. The moon reveals dots. The number of dots is tied to how many edges of the triangle light. A high count forces nearby edges on. A zero-style count forces them off. Work from a corner where the count leaves only one legal pattern, then move inward.

Draw the grid yourself. A filled solution copied from someone else’s panel is Unverified, and a rotated triangle makes that copy land on the wrong edges. If the moon is not showing dots, you are not on this method yet — park the light the way the moon guide describes, then recount.

Extract digits from an earlier box

The last red-door family points back at answer boxes you already earned. The new panel repeats those shapes and lights specific positions. Copy only the digits that sit under the lights. Leave the unlit digits out.

A community note describes the grouping as 1, then 2, then 1, and calls the result a four-digit code. Both the grouping and the length are Unverified until your panel shows them. The method does not change if the length differs: extract the lit positions, in the order the panel reads, and enter that. A code that reuses an entire earlier answer is the common miss.

When you can name which of the five methods is on screen, use the fork in the next section before you mix a line count into a segment dot.

Where the row sends you

Elevator digits are the case that looks like “a code someone should have posted” and is actually your map. That cursor is next. Sliders and the diamond grid are boards, not doors, so they sit after the clam. The right-edge row is a patch check, and it is the last section.

What a copied melody gets wrong

A melody from a thread skips the rotation you actually have. If your cracks join in a different spin, the upright direction changes and the notes change with it. Build the shape, then read. The creature that holds the puzzle is listed on creatures. Sliders and the diamond grid are the boards that fail for a blocked exit or an odd symbol, which is next.

Purple 4×4 sliders

The purple puzzle is three sliding blocks on a 4×4 grid, with two extra cells on the right. One block has to leave the puzzle area through that side. The other two have to rest on buttons. Plan the exit before you slide. A block parked in the extra cells can seal the only way out, and the board will look unsolvable when it is only clogged.

If you cannot see a path that frees one block and parks the other two, undo to the start. Forcing the exit block into a corner is the usual stall. No minimum-move list is verified for this page, so a posted step count stays Unverified. The goal shape is the check: one block gone, two blocks on buttons.

Diamond grid, slots 1 through 18

The diamond grid takes symbols from the diamond-map pages and puts them in slots numbered 1 through 18. Most symbols match a slot by the mark printed on the page. One page can show a symbol that shares a border with its neighbors and still sits in the odd position. That highlight is the exception you place by hand. Confirm the odd mark on your own pages before you treat a neighbor as the answer.

Community notes call this the fourth Tome chest. That index is Unverified. Your chest count is whatever your save shows. Do not fill slots 1–18 from a string you remember from another page — a shared border is exactly how that string lands one slot off. Pages, including the far-right leaves, are catalogued on the Tome.

If neither board is on screen and the right edge of the map still will not open, the next section is the patch check.

Knowledge gate versus a real stick

A knowledge gate still has doors, floors, and a way back to a checkpoint. You are missing a symbol, a telescope, or a page. Public notes put two late Tome pages on the far-right telescope path. That placement is Unverified. Check the Tome against the leaves you actually hold. Players have reached that edge with observatories already done and still needed a clue sitting in the current room. Search the room before you leave it.

A real stick is different: a lilypad edge you cannot walk off, a pressure plate that stays down, or a body wedged in collision. Those are the 1.0.08 and 1.0.10 cases. Update, reload the checkpoint, and only then repeat the puzzle method. Region layout for the swamp, the purple zone, and the right side is on areas.
