Nightfall

Nightfall is a calm, minimalist take on the classic Lights Out puzzle. A field of stars glows against the night sky, and your task is simple to grasp yet quietly addictive: turn them all off.

Tap a star and it flips, together with its four neighbours above, below, left and right. Every tap ripples across the board, so switching off the very last light becomes a gentle puzzle of order and parity. There is no timer pressure and no clutter, just you, the stars, and the satisfying moment the whole sky goes dark.

★ HOW TO PLAY
Tap any star to toggle it and its neighbours between lit and dark. Clear the entire board to complete the level. Easy to learn, with puzzles that quietly deepen as you go.

★ FEATURES
🌙 Endless, hand-tuned levels — every board is generated from its level number, so the supply never runs out and level 100 is the same for everyone. Difficulty rises smoothly from a 3x3 warm-up to intricate 7x7 grids, without a wall.
⭐ Always solvable — each puzzle is built to be winnable, and the game computes the exact minimum number of moves, so the challenge is always fair.
🏆 Three-star mastery — finish a level to earn a star, then match the optimal solution to earn all three. There is always a cleaner solve to chase.
↩️ Unlimited undo and restart — experiment freely, step back a single move, or reset the board whenever you like.
⏱️ Personal bests — your finest moves and time are saved for every level you clear, alongside overall stats for levels completed and stars earned.
🌌 Made to relax — a twilight palette, gentle star-glow animations, soft haptics and quiet sound effects. Everything is tuned to unwind, not to rush.
🔒 Fully offline and private — no ads, no analytics, no accounts, no network at all. Nightfall never asks for the internet and keeps everything on your device.

★ WHO IT IS FOR
Nightfall suits anyone who enjoys a thoughtful, low-stress puzzle, whether you want a quick five-minute wind-down before bed or a long, quiet session chasing perfect solves. If you like Sudoku, nonograms or classic logic games, the Lights Out mechanic will feel instantly familiar, with just enough depth to keep pulling you toward the next board.

Settings keep you in control: toggle sound and haptics, adjust the volume, and reset your progress whenever you want. The interface is clean and distraction-free, wrapped in a soft night-sky theme that is easy on the eyes in the dark.

No pressure, no noise, just a quiet sky full of stars waiting to be switched off, one level at a time.

Turn out every light. Sweet dreams.
