FAQ

Short answers for launch-day Paint My Keyboard planning.

How does the calculator rank upgrades?

It calculates income per minute, simulates each upgrade, then divides cost by the extra income per minute to get payback time.

What formula does the planner use?

Income per minute equals roller speed times cash per key times paint multiplier. Payback equals cost divided by the income increase.

Are expansion gains exact?

Expansion is modeled as a 30% cash-per-key gain for planning. Treat it as a launch-day estimate until more in-game tests are available.
