Free Biology Games Online
Explore living systems through play. This collection of free biology games turns real concepts into mechanics: command immune cells against pathogen waves in Immune Rush, sort dividing cells through their checkpoints in Mitosis Manager and match drugs to diseases in Pharma-Fix.
You can edit DNA in CRISPR Snipe, defend your gut microbiome in Microbe Midway, watch allele frequencies drift in Drift King or roll into a cryptobiotic tun in Tardigrade Tun. Every game runs instantly in the browser with no download or sign-up, ready for classrooms, homework and curious minds.
Clockwork Cell
Master the 24-hour molecular clockwork cycle by translating PER and TIM proteins, shuttling dimers into the nucleus to repress transcription and triggering the Cryptochrome dawn flush.
Pheromone Highway
Guide foraging ant swarms using chemical recruitment trails and alarm repellents to solve emergent shortest paths through stigmergy.
Tardigrade Tun
Shift between active swimming and cryptobiotic tun state to withstand lethal solar UV flares, flash freezes, boiling acid and cosmic vacuum.
Wood Wide Web
Guide mycorrhizal fungal threads through subterranean soil, barter nutrients for glucose with trees and dispatch pest warning signals.
MicroRNA Patrol
Control Argonaute complexes to regulate mRNA translation. Balance cellular homeostasis through exact catalytic cleavage and partial seed dimmer braking.
FoldCraft
Snap secondary backbone motifs, trigger hydrophobic core collapse and sculpt catalytic active site pockets.
Immune Rush
A fast-paced arcade game about the immune system.
Microbe Midway
A frantic shooter about defending your gut microbiome.
Tolerance Titans
A tower-defense style game about immune tolerance.
The Transcriptionist
A typing game where you transcribe DNA to RNA, one base at a time.
Memory Load
A memory-matching game about how sleep consolidates memories.
Mitosis Manager
A fast-paced sorting game about the cell cycle and cancer prevention.
Differentiation Director
A puzzle game about differentiating stem cells by matching signal pathways.
Bone Marrow Madness
A fast-paced resource management game about creating blood cells.
Gene Juggler
A fast-paced puzzle game about discovering gene sequences.
Pharma-Fix
A drag-and-drop game about drug effects and side effects.
Containment Crew
A fast-paced reaction game about applying public health interventions to stop outbreaks.
Chemo Crossroads
A fast-paced shooter about chemotherapy. Target cancer cells and spare healthy cells.
Toxin Takedown
A fast-paced game about biomagnification. Catch fish but avoid the concentrated toxins!
CRISPR Snipe
A physics-based slingshot game about CRISPR gene editing and chromatin navigation.
Epigenetic Painter
A fast-paced chromatin remodeling game. Stamp methyl tags to silence transposons and brush acetyl marks to express genes.
Phage Hunter
A fast-paced physics and docking game about bacteriophages and antibiotic-resistant superbugs.
Stomata Sprint
A valve balancing reflex game. Pump potassium ions to swell guard cells open for carbon dioxide intake and clamp shut against dry heat waves.
Hydrothermal Haven
A fast-paced deep-sea marine ecology arcade game. Manage a hydrothermal vent ecosystem, channel sulfide plumes and shield tubeworms from volcanic eruptions.
Gross Anatomy Lab
Master human donor dissection techniques, swap surgical tools to expose thoracic organs and identify vital landmarks without cutting delicate nerves.
Triage Rush
A fast-paced clinical diagnosis game where you triage acute symptoms, stabilize fluctuating vitals and deliver targeted treatments before patients crash.
Patho-Scan
Investigate patient blood smears and tissue biopsies, adjust optical focus depth, swipe differential stains and tally cell ratios against time.
Petriquarium
Nurture Pichia yeast, Spirulina algae and Streptomyces fermenters, harvest insulin and phycocyanin tokens and defend bioreactors against lytic podoviruses in this microbial arcade game.
Trophic Frenzy
Guide microscopic swimmers through pelagic freshwater food webs, graze cyanobacteria as a ciliate, swallow ciliates as a rotifer and evade hydras as daphnia in this science arcade game.
Epitope Striker
Type peptide epitope sequences to synthesize monoclonal antibodies and neutralize invading pathogens before they breach the endothelial barrier.
Chloroplast Citadel
Defend leaf veins against invading aphids, spider mites and caterpillars using thylakoid photon harvesters, guard cell turrets and ABA emergency abscission valves in this botany strategy game.
Lab Dash
Dash across the wet lab bench, manage experiment orders, pipette reagents, spin centrifuges and deliver certified test results before researcher patience expires in this laboratory time management game.
Drift King
Steward an island herd of Driftites through pure genetic drift: feed carrying capacity, weather bottleneck storms, seed founder colonies and ride runaway mate fads while allele frequencies lurch by luck alone.
Spin Echo
Run a real MRI pulse sequence: fire 90 and 180 degree RF pulses, refocus dephasing proton spins into an echo and encode k-space with gradient coils to diagnose tumor, fat, fluid and edema from their T1 and T2 signatures.
Peppered Pursuit
Hunt peppered moths as a hungry flycatcher across generations: soot darkens the forest, lichen restores it and every catch steers the allele frequency bar in this Kettlewell natural selection arcade game.
Punnett Pen
Run a breeding farm under contract: pick parents with hidden genotypes, watch real Punnett squares fill at Mendelian ratios and prove carriers with test crosses before the season drains.
ATP Avenue
Sprint a glucose molecule through glycolysis, lap the Krebs cycle wheel and ride the electron transport chain to the ATP synthase jackpot in this cellular respiration platformer.
Rhodopsin Relay
Pilot a fiber-optic implant inside a living brain: fire blue light to excite relay neurons and yellow light to silence seizures on millisecond timing.
Sanctuary Tycoon
Rebuild a rundown reserve: fence habitat-matched enclosures, pair founders by genetic distance, dodge poachers and rewild endangered species.
Acre Algebra
Grow crops by balancing N-P-K, soil pH and organic matter while keeping fertilizer runoff out of the creek.
