🏢 Lights

What is Lights

Lights is Deduza's take on Binairo (Takuzu): the grid is the front of a building at night. On every floor and in every column, half the windows are lit and half are dark, never three alike in a row, and the = and ≠ clues link matching or opposite windows. Solve it and you meet the building of the day and one of its residents. A new building every day, in three levels.
