Dusk Sudoku

Dusk is Sudoku made calm.

A quiet, meditative sudoku with one promise: it never pushes you. No countdowns, no loss-aversion guilt, no flashing red. Soft feedback, generous whitespace, and a warm dusk palette make this free number puzzle feel like a quiet room to focus.

CALM BY DESIGN
• Warm paper tones and low-saturation color — never harsh.
• Conflicts are shown gently (a soft underline, not an alarm).
• Slow, breathing motion. Reduce-motion is fully respected.
• Colorblind-safe: meaning is always carried by shape and weight, not color alone.

A SUDOKU FOR EVERY LEVEL
• Four difficulties: Easy for beginners, Medium, Hard, and Expert for logic veterans.
• Pencil notes, number-first input, undo, and a 50/50 cell highlight.
• Learn sudoku techniques with coaching hints (Naked Single, Hidden Single, Locked Candidates, and more) — a gentle teacher, not just the answer.
• Cell-reveal hints when you want a nudge.

A DAILY SUDOKU CHALLENGE
• A new daily puzzle every day — the same puzzle for everyone, worldwide.
• Each daily challenge can be completed once. Watch your monthly calendar fill up, day by day.
• Missed a day? Open it from the calendar and complete the picture.
• A gentle streak with Rest Days: miss a day and your record carries over, no shaming.

QUIET PROGRESS
• A score for every solve — difficulty, time, and a clean board all count.
• Levels that grow with you, at your own pace.
• Three small daily missions with hint rewards — never a chore.
• Personal bests per difficulty: fastest time and highest score.

HONEST AND QUIET
• Play offline, anywhere — no connection needed for your daily brain workout.
• Ads are clearly labeled. Rewards say exactly what you get ("Watch a video for 1 hint").
• No forced or interrupting ads. Close is always available.
• Optional, opt-in reminders — off by default.

Dusk — a calm sudoku, a quiet room that helps you focus.
