MONOMOON guide, map & puzzle help

MONOMOON combines platforming and point-and-click interaction in a small open world. Knowledge opens up your options: the symbols you encounter are useful information, not simply decoration. This guide starts with a practical skill you can reuse across the map, book pages, and the Red Temple. The number reference below reveals part of the game's discovery process; skip to the notebook if you prefer to decipher it yourself.

Read MONOMOON digits from 0 to 9

The ten MONOMOON symbols represent ordinary decimal digits. Match each shape to the reference, then read the symbols in order. On coordinate displays, the first symbol is the tens digit and the second is the units digit. Two symbols do not mean that you should add the values: a 1 followed by a 4 means 14, while a 0 followed by a 7 means 07.

Some MONOMOON digits look similar at a glance. Compare the direction of the branches and whether a line is horizontal, vertical, or diagonal. The 0 has an upright stem and a bottom bar; the 2 places its bar at the top and has a diagonal branch. Use the complete shape, rather than treating every crossed line as the same symbol. The book uses the same digit system for its page numbers.

Reveal your MONOMOON map coordinates

1. Open the map after unlocking it near the start of the game.
2. Light the moon at the map's top edge.
3. Read the coordinate symbols that appear along the bottom edge.
4. Convert the symbols to digits using the reference above, keeping each pair together.

The MONOMOON map has 29 columns and 18 rows. X increases from left to right; Y increases from bottom to top. The bottom-left cell is (01,01), and the top-right cell is (29,18). This bottom-up row numbering matters: counting down from the top gives you a different location. A coordinate identifies a map cell, not a precise position within that screen.

Worked example: the MONOMOON Red Temple approach

The Red Temple entrance is at (15,08). Read that as column fifteen from the left and row eight from the bottom. The approach described in our Red Temple entrance and puzzle guide starts at (13,07), with a save point at (13,05). Those cells share a column, but they are not interchangeable. Use the locator below to distinguish them before following the lift instructions.

Turn a coordinate into a useful MONOMOON note

Keep the coordinate in the location field alongside a short landmark name, such as “Red Temple entrance (15,08)”. Record the obstacle separately from its proposed solution. If you leave the area, the coordinate helps you identify the same screen again; it does not imply that the shortest geometric path will be accessible. Save points, lifts, and room connections still determine your route through MONOMOON.

Find, edit, and back up MONOMOON notes

Search matches the location, observation, and next-step fields. The progress filter narrows those results to open, revisit, or solved notes. Choose Edit to change an existing entry; Cancel edit preserves its saved version. These controls organize your own records and do not change anything inside MONOMOON.

Export downloads every saved note, including entries currently hidden by a search or filter. Keep that text file before clearing browser storage or switching devices. Export is a readable backup, not a game save or an import file. Notes on this website are separate from notes entered on another browser or address.
