The dig
Hit the rock. Bones fall off. They land where they land and stay there.
Bone Orchard is a singleplayer idle game. You run a company of skeleton monks excavating a fossil buried under the rock. Every hit knocks bones loose, and every bone ends up somewhere on the ground.
Reach
How far a bone flies decides who can carry it home. Your first workers only pick up what lands close. Anything further out sits where it fell until you hire something that reaches it. So you spend the game hiring things that reach further.
Collapse
When the heap gets tall enough it collapses, and everything you own is worth four times more.
Do that ten times and the monks can start building something.
Remember
When an orchard stalls, remember it. You start over with nothing, but you keep your memories, and each one buys a talent at the memorial. Vows make an orchard harder on purpose. Keep one to its tier and its reward stays for good.
The moon
A hundred memories and three kept vows wake her. A steady player gets there in about eight hours, and the orchard keeps going after she opens her eyes.
