Immune Match Every microbe wears a marker — tap the antibody that fits like a key, and watch memory cells learn it. 
Immune Response Put the body’s calm defense in order — barrier, helpers, memory — and see why the second time is milder. 
Microbiome Lab Pick a place — gut, mouth, skin, or soil — and grow a balanced community of friendly microbes. 
Growth Curve Lab One germ doubles, then doubles again — predict the colony size before the growth curve reveals it. All activities

Immune Match Tap the antibody that fits each microbe’s marker — memory cells recognize it faster next time. Immune Response Order the body’s quiet defense — barrier, then helpers, then memory. Microbiome Lab Tend a living microbiome in the gut, mouth, skin, or soil and keep it in balance. Microbiome POE Predict whether the beneficial share of a community will rise, fall, or hold steady under a care choice — then the same simulator runs the days and reveals the trajectory. Growth Curve Lab Predict how big a colony gets — see why doubling races past a straight line. Teach the Cast Teach a microbe idea to a cast member still learning it — teaching makes it stick.
Practice & play
Mixed Practice A short round across the kits you have played — brought back to make it stick. MicrobeLab Sprint Race your OWN best on what you already know. Timer optional, no penalty for a miss. Trick Questions Brain-teasers with a twist — spot why the obvious answer is a trap. MicrobeLab Duel 2–4 players take turns on one device — same questions, highest first-try score wins. Or open an online room. Progress Your levels, streak, and how each skill area is coming along — saved on this device. Progress report For grown-ups — a private on-device snapshot mapped to the skill areas. Export a CSV or print.

Meet the cast — the characters who teach this
-
Lacto Lactobacillus + helpful-bacteria — 'Friend in your food. Friend in your gut.' -
Yeast Saccharomyces + helpful-fungi — 'I make air inside bread.' -
Photo Cyanobacteria + photosynthetic-microbes — 'Sunlight. Then air. Then everything else.' -
Net Mycorrhizal-fungi + nitrogen-fixers — 'Forests talk through me.' -
Spore Pathogens (opt-in gated) — 'Some friends. Some not. All real.' -
Guard Immune cells (T-cell / macrophage / B-cell) — 'I check IDs. Patient + careful.' -
Crumble Decomposer microbes that break down dead leaves and scraps into rich soil, so nothing is wasted and everything begins again. -
Thrive Extremophile microbes that make a home in the hottest, coldest, saltiest places, showing life finds a way almost anywhere. -
Shimmer Bioluminescent microbes that turn energy into their own soft glow, lighting ocean waves and partnering with animals like tiny lanterns. -
Colony Microbes that build biofilms together, cooperating and protecting each other, because they are far stronger as a community than alone.
