Words Sorting Logic in Bubble Word Jam Level 731
Each puzzle in Bubble Word Jam is solved by grouping words that share a common theme. Some categories contain direct words, while others (like STUDIO ARTS) include a nested subcategory with its own set of words. The key is to recognise the meaning or domain that ties the words together. Below is a detailed explanation of every category.
PERSONALITIES
This group collects words that describe traits or types of people’s character.
- BAD BOY belongs here because it is a term for a rebellious, often charming person.
- BOOKWORM describes someone who loves reading and studying.
- BRAVE refers to a person who shows courage.
- OUTGOING means a sociable and friendly personality.
All four words label different kinds of human personalities or temperaments.
OBSERVATORY EQUIPMENT
These are devices or tools used in an astronomical observatory to study celestial objects.
- SPECTROGRAPH is an instrument that separates light into spectra for analysis.
- SPECTROMETER measures the intensity of light at different wavelengths.
- DETECTOR captures light or other signals (e.g., CCD cameras).
- COMPUTER processes data collected by the other equipment.
Together, they form a set of essential hardware in a modern observatory.
DIGITAL FILE TYPES
This category includes common file extensions used for digital documents, images, audio, and portable formats.
- DOCX is the file format for Word documents.
- JPEG is a standard image compression format.
- MP3 is a popular audio file format.
- PDF is a portable document format for sharing text and graphics.
Each word represents a distinct type of digital file.
COVERT ACTIVITIES
These words refer to actions or concepts that involve secrecy, deception, or hidden motives.
- CONSPIRACY is a secret plan by a group to do something illegal or harmful.
- DISGUISE is a way to hide one’s true identity.
- HIDDEN AGENDAS are undisclosed motives behind actions.
- SECRECY is the practice of keeping information hidden.
All relate to activities done in a concealed or underhanded manner.
STUDIO ARTS
The main idea is artistic practices that take place in a studio setting, especially those involving hands‑on creation. This category has three direct words and one nested subcategory.
- PHOTOGRAPHY is the art of capturing images using a camera.
- WEAVING is the craft of creating fabric by interlacing threads.
- CERAMICS is the art of making objects from clay.
These three are broad studio‑based arts. Within ceramics, there is a specialised sub‑domain.
POTTERY
Pottery is a subset of ceramics focused on making objects like pots, bowls, and vases. The words under POTTERY are technical terms used in the pottery process:
- BODY refers to the clay mixture used to form the object (the “clay body”).
- FIRING is the process of heating the clay in a kiln to harden it.
- BURNISH is a technique of polishing the clay surface before firing.
- COILING is a hand‑building method where clay is rolled into long coils and stacked.
These four words belong under POTTERY because they are specific steps or materials in pottery making, all part of the larger STUDIO ARTS category.
EYEGLASS PRESCRIPTION
This category contains terms that appear on a standard eyeglass prescription, used to correct vision.
- AXIS indicates the orientation of astigmatism correction (in degrees).
- CYLINDER measures the amount of astigmatism.
- OD stands for oculus dexter (right eye).
- PRISM is used to correct double vision or eye alignment.
All are key components of a written prescription from an optometrist.
GO-OUT ESSENTIALS
These are items of clothing that people typically wear when leaving the house.
- FOOTWEAR includes shoes, boots, etc.
- JACKET is an outer garment.
- JEANS are casual trousers made of denim.
- PANTS are a general term for trousers.
Each word represents a basic part of a going‑out outfit.
TELESCOPE
This group covers words related to telescopes and their use in astronomy.
- HUBBLE is the famous space telescope (the Hubble Space Telescope).
- MIRROR is a key optical component in reflecting telescopes.
- APERTURE is the diameter of the telescope’s main light‑gathering lens or mirror.
- OBSERVE is the action of using a telescope to study the sky.
All are directly connected to telescopes and astronomical observation.
ELECTRIC FIXTURES
These are common components or devices found in electrical systems for lighting and power.
- DIMMER is a switch that adjusts the brightness of a light.
- LIGHT BULB is the source of light.
- SWITCH controls the flow of electricity (on/off).
- WIRE conducts electricity between components.
Together, they form a set of basic electric fixtures used in homes and buildings.
This explanation covers all nine categories and their nested subcategory for Level 731. Understanding the shared meaning behind each group helps you see why the words are placed together.
