How to play Abrakadaver
Find the Mystery Bodypart by making guesses and using the anatomy that remains after each one.
- 1
Make your first guessEnter the name of any body part currently shown in the game.
- 2
Watch what remainsAn incorrect guess disappears. When it shares a useful anatomical area with the Mystery Bodypart, unrelated parts disappear too.
- 3
Find the answerUse the remaining model and the groups beneath the guesser to choose a more specific guess. Continue until only the Mystery Bodypart remains.
Try removing body parts
This example hides the left kidney and begins with every anatomy system represented. Use the button to remove the labelled part and watch the possible answers shrink.
When a guess and the answer share a more specific anatomical area, everything outside that area falls away. If the area does not change, only the incorrect guess is removed.

Read the clues
Every guess changes the model and adds another level to your guess history. Read both together before choosing the next part.
- Parts removed
- After each guess, the game reports how many parts disappeared. A large change usually means you found a more specific area.
- Anatomical groups
- Group names show the path from a broad area, such as the trunk, toward a more specific structure, such as the kidney.
- Previous guesses
- Incorrect guesses stay in the list under the group they revealed, even though they have disappeared from the model.
- Revisit a clue
- Select a group to reconstruct that area in the viewer, or select a previous guess to bring that removed part back for comparison.
Anatomy systems
Each body part is colour-coded by its anatomy system. The same colour and icon appear beside related groups and guesses.
| System | Icon |
|---|---|
| Alimentary systemThe digestive tract and accessory organs that break down food, absorb nutrients, and eliminate solid waste. | |
| Cardiovascular systemThe heart and blood vessels that circulate blood, delivering oxygen and nutrients and carrying away wastes. | |
| Endocrine systemGlands and hormone-producing organs that regulate processes such as growth, metabolism, reproduction, and stress responses. | |
| Genital systemThe reproductive organs and supporting structures involved in producing reproductive cells and enabling reproduction. | |
| Integumentary systemThe skin and related structures that form the body's protective outer covering and help with temperature control and sensation. | |
| Lymphoid systemLymphoid organs and tissues that support immune defense, house lymphocytes, and help filter lymph and blood. | |
| Muscular systemMuscles and their associated tendons that produce movement, maintain posture, stabilize joints, and generate heat. | |
| Nervous systemThe brain, spinal cord, nerves, and related structures that sense information and rapidly coordinate the body's responses. | |
| Respiratory systemThe airways and lungs that move air and exchange oxygen and carbon dioxide between the body and the environment. | |
| Sense organ systemSpecialized structures for detecting stimuli involved in sight, hearing, balance, smell, taste, and other senses. | |
| Skeletal systemBones, cartilage, joints, and supporting structures that provide shape, protection, stability, and leverage for movement. | |
| Urinary systemThe kidneys, ureters, bladder, and urethra, which filter blood, regulate fluid balance, and remove waste as urine. |
Daily and practice games
The daily game provides one shared Mystery Bodypart each day. Practice games can be replayed whenever you want and do not affect the daily result.
