Mycelia — Idle Merge Grove

An idle game played on a board. Sprout glowing caps, drag matching ones together, and arrange your grove so neighbors feed neighbors.

Under the leaf litter, something is thinking.

Mycelia is an idle-merge hybrid: your spores buy sprouts, sprouts merge into brighter caps, and WHERE you place things matters. Every cap grows faster next to caps its own size or bigger — so the grove rewards tending, sorting, and the quiet satisfaction of a well-arranged board.

• A living hex board, 19 cells growing to 61 • Drag matching caps together to merge — twelve levels, lime-glow to white-hot • Adjacency bonuses turn placement into strategy • Merging two Mother Caps releases an hour of spores in one burst • Fairy Rings: complete the circle, reset the board, keep the essence (+10% each, forever) and spend it at the Fairy Court • Auto-sprouting, deep roots, Heartwood and more court gifts • The grove grows while you're away (up to 14 h) • Entirely on-device: no account, no internet, nothing collected

Tend it for a minute or an hour. The mycelium doesn't mind. It remembers.
