About

Read full description

build a city, guided by sightlines. rooftops is a chill, beautiful take on the classic skyscrapers (towers) logic puzzle. every row and column holds each building height exactly once, and the circled clues tell you how many rooftops an observer can see down the line — taller buildings hide the shorter ones behind them. tap to raise towers until every sightline agrees. your city stands. fair by design. every board has exactly one solution — no guessing, ever. the generator proves it before you ever see the puzzle. it explains itself. tap any clue and an eye appears, tracing its line of sight across your city. a gentle two-minute tutorial teaches the whole idea hands-on, with no walls of text. two ways to play: · classic — every clue shown. pure skyscrapers logic. · mystery — some clues are dug out, replaced by standing towers and inequality hints. same logic, new texture. today's board. one fresh puzzle per size, per mode, every day — the same board for everyone worldwide. a streak too, if you like keeping one. chill on purpose. soft skies, glossy isometric tiles, optional lo-fi music. the clock counts up, never down — beat your own time or ignore it entirely. no lives to lose. boards from a friendly 3×3 village to a brutal 6×6 metropolis. works offline. a logic puzzle you can breathe in.
