A quieter kind of nonogram — where every puzzle you solve becomes a constellation in a night sky that is entirely your own. Noctagram is a picture-logic puzzle game (nonogram / picross / griddler) wrapped in a calm, star-lit world. Read the number clues, fill the grid row by row — but here the finished picture doesn't just vanish. It ignites. A single line traces through your solved cells, a constellation takes shape, and you name it and seal it into your sky forever. Solve enough, and the darkness fills with stars only you have lit. — WHY NOCTAGRAM IS DIFFERENT — A sky you build, not a gallery you clear. Most nonogram games hand you a pixel picture and move on. Here, each solution is a named constellation added to one living, growing night sky. Your progress isn't a percentage — it's a map of light. 248 constellations, every one named by hand. No random shapes. Each puzzle was designed and christened in the style of a real star chart — unique, quietly poetic, waiting in the dark for you. Made to be calm. No timers. No lives. No pressure. Just clean logic, soft light, and a gentle soundscape. Play a single grid to unwind, or lose an hour among the stars. — HOW IT PLAYS — • Classic nonogram rules — deduce the picture from the number clues. • Puzzles from small and cozy to large and deep (5×5 up to 20×20). • A warm coral fill and a cool marking cross — easy on the eyes, clear at a glance. • A hand-crafted "sealing" ceremony every time you complete a puzzle. • Auto-save and one-tap continue — pick up exactly where you left off. Fill the grid. Light the stars. Name your sky. Noctagram — picross beneath the night.
