Quill Star Atlas

Open a parchment atlas under a deep indigo night sky and let the stars guide your reasoning. Quill Star Atlas is a calm logic-grid (Einstein) deduction puzzle game: each chapter gives you a handful of clues and asks you to pair the right star fairy with the right constellation and bloom. Tap lattice cells to mark possible or impossible, and the grid gently cross-eliminates as a row or column collapses to a single truth.

No timer pressure. No ads. No in-app purchases. Just you, a quill, and the celestial chart.

FEATURES • Pure logic-grid (Einstein) deduction across two or three categories per puzzle • Auto cross-elimination - the lattice gently propagates each row/column truth so you can focus on the next clue • Clue scroll on the side highlights the clue you're currently considering • Constellation Atlas progression - every solved puzzle inscribes a small star chart in your atlas; a full chapter unfolds into a navigable celestial map • Six theme packs unique to this app - star fairies, constellations, blooms, and more • Vintage cartography aesthetic - DM Serif Display typography, gold star-glow accents, brass astrolabe ornaments on parchment • Fully offline, no account required • No ads, no in-app purchases, no data collection • 4+ age rating, family friendly • Portrait, iPhone + iPad universal

WHO IT IS FOR A quiet evening read for puzzle lovers, mystery-solvers, and anyone who likes a calm mind challenge. Designed for the wind-down end of the day rather than the rush of the morning commute.
