Trailer
Real gameplay from the daily puzzles, the hints, the Learning Academy, and the themes, set to koto music. There's no voiceover, so it works with the sound off.
Screenshots
Every screenshot here comes straight from the game.
Easy, Medium, Hard, and Extreme. The same four puzzles appear on every device each day, right on the home screen. To play without risking your streak, start a random board instead.

Tap a number, then tap a cell. Add pencil marks, turn auto-check on or off, and undo any slip. The timer stays small and out of the way. Undo, Redo, Notes, Hint, and Erase sit to the side of the board.

Stuck? A hint starts with a nudge, then names the technique (Naked Single, Hidden Single, X-Wing), then explains why it works. Only then can you tap Apply. You can go straight to the answer, but reading the explanation is how you get better.

The Learn tab has Controls & Shortcuts, The Basics, a Technique Academy with 40 lessons, and 39 sets of guided practice. Learn a pattern, practice it, then use it on a real board. Practice mode works at any difficulty and doesn't touch your streak.

Morning Paper, Sakura, Midnight Glass, Ocean, Forest, Zen Garden, and more. Twenty light and dark themes change the board, the numbers, and the colors. Set it to follow your system theme and it switches between light and dark with your device.

The archive keeps every daily you've finished. The stats screen shows your best time for each difficulty, your current and longest streaks, and the stars you've earned. Cloud save, leaderboards, and achievements work where your platform supports them.
