The Ladder · From a Basement Wheel to a Tear in SpaceRarity here is not a label — it is the machine. Seven tiers, and the step between neighbours is exactly ×3: 10 W at the bottom, 7 290 W at the top, 729× apart.
Power is the output, not a score. One watt mines 1 kWh a day, so the number written in a machine is what it brings in — no rate to look up, no curve to read. The grid splits one fixed daily pool by power, which is why a merge cannot print energy: it only changes whose share is bigger.
The ladder is walkable. 2 machines of the same tier burn into one a tier higher, paid for in mined energy, and 32 common machines become a single mythic. Supply is exact and not a target: 4 000 machines, laid out in advance.
