Blood Type Puzzle

This interactive 3D puzzle was designed as a hands-on educational tool to help students understand the principles behind the ABO and Rhesus blood group systems. The model provides a visual and tactile way to explore how blood types are determined, how antigens and antibodies interact, and why certain transfusions are compatible or not.The puzzle includes blood samples and patient cards that must be matched correctly based on the presence or absence of A, B, and Rh (D) antigens. Players test compatibility by simulating agglutination reactions and use logical reasoning to deduce each individual’s blood type.This model is ideal for biology students, healthcare trainees, or anyone interested in learning about blood typing in an engaging, memorable way. It’s now available as a downloadable 3D-printable file so you can print and assemble your own set.
