Two rules every rung keeps

The Fade Rule. Every game ends on a plain screen: the same numbers with the skiing words gone, so the maths leaves with you.

The Own-Lane Rule. Your numbers are compared only with your own past, never with anyone else's, and they stay on this device.

Problems built on something you love help most when the context carries the maths, not when it decorates it. These ladders are a design, not a promise.

Ask a grown-up tonight: “Which run would you choose again tomorrow, and why?”
