Galaxies – Spiral Symmetry

About

Enclose each star and divide the grid into point-symmetric "galaxies." Galaxies (Spiral Galaxies / Tentai Show) is a calm logic puzzle with one simple rule and surprising depth. Every board has exactly one solution, and you can always reach it by reasoning alone. ONE ANSWER. NO GUESSING. Every board is checked by a built-in solver before you see it: - it has exactly one solution - every cell can be worked out step by step You will never have to fill in the last few cells on a hunch. HOW TO PLAY Divide the grid into galaxies so that: - each galaxy contains exactly one star - each galaxy looks the same when rotated 180° around its star - every cell belongs to exactly one galaxy Tap a star to select it, then tap or drag across cells to color them in. Cells touching a star start out filled. FOUR LEVELS - Easy (8×8): learn the rule - Medium (9×9): enjoy reading the symmetry - Hard (10×10): think one step ahead (try a color, spot the contradiction, rule it out) - Expert (12×12): a big board to settle into REASONS TO COME BACK - Daily puzzle: the same board for everyone, with streaks and a calendar - Constellations: light up all 12 as you keep solving - Stats: puzzles solved, streak, no-hint rate and total time - Board themes: Nebula, Aurora, Sakura and Sunset EASY TO PLAY - Undo, Clear and Hint - Optional mistake highlight - A short tutorial with a small practice board - Works on iPhone and iPad, with a larger board on larger screens - Dark Mode, English and Japanese PERFECT FOR - Fans of number and pencil puzzles looking for a new logic puzzle - Solvers who want to reason it out, not guess - A quiet brain teaser before bed or on the go - Anyone building a small daily habit PRIVACY - No account needed - Your progress is stored only on your device - No personal data is collected, and there is no tracking - Puzzles work fully offline.
