Darkle

Every night, one building. Tap a window and it flips off — but its four neighbours flip with it. Sounds easy the first time. Then comes the second window.

Everyone in the world gets the same building each night, and every building has a par: the fewest taps possible. Match it and the night counts as perfect. Two minutes in the evening, then it's done.

Meanwhile people move into the lit windows — a cat on the sill, someone with a guitar, a flickering television. On weekends the building grows taller. At Halloween it turns purple.
