HyphoSphere

HyphoSphere is a fungal idle game in which you grow a mycelial empire from a single filament toward a cosmic singularity. Click to harvest nutrients, build organisms and spread your network across the planet and beyond.

Grow your network

You begin with a Simple Hypha and can unlock 10 distinct organisms. They include Rhizomorphs, robust cords that explore new substrates; Mycorrhizae, which form symbioses with tree roots and feed both you and the forest; and Carpophores, visible mushrooms that produce spores. Other forms include the Forest Network, through which you control the Wood Wide Web; Cordyceps Parasites, which infect insects and put them to work for you; Fungal Consciousness, which lets the network think, optimise and expand; and the Mycelial Singularity, where the cosmos becomes your substrate.

Events on the canvas

Your mycelium pulses and grows across a dynamic canvas, with drifting and bursting particles. Random events can appear at any time:

• Bioluminescent Spore: catch it for ×7 production or 15 minutes of nutrients at once.
• Spore Storm: gather spores drifting across the canvas.
• Bacterial Invasion: repel the attack before it damages your network.
• Cosmic Mycorrhiza: encounter a rare, radiant event.

Sporulation and achievements

Once your empire is large enough, you can trigger Sporulation, resetting your progress in exchange for Primordial Spores. Each spore permanently increases production by 5%. The game includes 100 achievements, from harvesting your first nutrient to reaching billions of clicks and cosmic transcendence. Achievements also power up Symbiotic Vitality, a bonus that scales with each milestone.

Play with Twitch chat

Twitch integration lets viewers interact with your game using chat commands. Viewers can click the mushroom with !click, vote for ×3 NPS for 20 seconds with !boost, vote to trigger a bacterial invasion with !invade, or vote to purchase an organism with !buy. The game has no rankings or competition; its fungal empire is built together.
