## Description

Every row, every column and every coloured region of the night sky hides the same number of stars – and stars never touch, not even diagonally. Reason out where they are, and watch them join into a constellation with its own name.<br><br>Constellations is a calm, clever star-placing logic puzzle. There is no luck and no guessing: every sky has exactly one solution, and you can always reach it by deduction.<br><br>HOW YOU PLAY<br>• Tap a cell once for a dot (no star here), twice for a star.<br>• Drag across cells to dot many at once.<br>• Auto-dots marks the cells a star rules out, so you can focus on the thinking.<br>• Rule breaks light up at once: touching stars, a crowded row, a region with no room left.<br>• Undo and redo any move.<br>• Every sky you solve joins your sky atlas, with its constellation and name.<br><br>HINTS THAT TEACH<br>Stuck? The hint first shows you where to look, then explains the reasoning – and only makes the move if you ask. The first time a new idea comes up, the hint explains it in general, so you learn the trick instead of just getting the answer.<br><br>280 SKIES, FOUR DIFFICULTIES<br>• Easy – small skies and a five-level tutorial that teaches every idea you need<br>• Medium – bigger skies and your first counting tricks<br>• Hard – 9×9 skies that need you to look at two rows at once<br>• Expert – 10×10 skies with two stars in every row, column and region<br><br>All 40 Easy levels and the first 10 levels of Medium, Hard and Expert are free. More levels come in one-time packs, or unlock everything at once. No subscriptions, no ads, no account.<br><br>MADE FOR THINKERS<br>• Plays fully offline<br>• No account, no ads: only anonymous usage stats and crash reports, which you can turn off<br>• Your progress and best times stay on your device<br>• A quiet night-sky look with soft chimes<br><br>If you enjoy logic puzzles, Sudoku, nonograms or star-and-queen placement puzzles, Constellations is your next favourite.
