HyphoSphere

Grow. Expand. Transcend.
HyphoSphere is a fungal idle game where you build a mycelial empire from a single filament to a cosmic singularity. Click to harvest nutrients, construct living organisms, and watch your network spread across the planet ... and beyond.
From Hypha to Singularity
Start with a single Simple Hypha and unlock 10 distinct organisms, each with its own identity on the living canvas:

Rhizomorphs : robust cords that explore new substrates

Mycorrhizae : symbiosis with tree roots, feeding both you and the forest

Carpophores : the visible mushroom, a spore factory in full bloom

Forest Network : you control the Wood Wide Web

Cordyceps Parasites : infect insects, make them work for you

Fungal Consciousness : the network thinks, optimises, expands

Mycelial Singularity : you have transcended biology. The cosmos is your substrate


A Living Network
The central canvas is alive. Your mycelium pulses, filaments grow outward, particles drift and burst. Random events appear at any time :

Bioluminescent Spore : catch it for ×7 production or 15 minutes of nutrients in an instant

Spore Storm : gather drifting spores across the canvas

Bacterial Invasion : repel the attack before your network is damaged

Cosmic Mycorrhiza : rare, radiant, extraordinary

Sporulation — The Prestige System
When your empire grows large enough, trigger Sporulation: reset everything and earn Primordial Spores. Each spore grants a permanent +5% production bonus. The cycle begins again : faster, richer, deeper.

100 Achievements

From your first harvested nutrient to billions of clicks and cosmic transcendence : 100 achievements track your journey and power up Symbiotic Vitality, a bonus that scales with every milestone you reach.
