Buildings

Buildings do not mine on their own, they multiply what the drill produces. Every level of any building adds +20% mining speed, and the levels of all four add up into one multiplier.

Building multiplier = 1 + 20% × (sum of all building levels)
The cap is 20 levels per building. All four at maximum give +1600% speed, so mining grows 17x. Fully upgrading every building costs 491,926 CROWN.

Prices per level

Levels 1–10 (tier I): base price × level number. Levels 11–20 (tier II, since 15 September): base price × 5 × 1.35 to the power (level − 11), so every next level costs 35% more than the previous one. Each building has its own base price. At tier II the building changes its look.

How the warehouse differs

The warehouse gives more than speed: it also sets how much ore and gold you can hold, and each of its levels doubles the capacity. Details are in the Warehouse section.
