Sudoku Haven
A daily Sudoku you actually look forward to.
Four fresh puzzles every day, plus a library of 450,000+ hand-graded grids across five difficulties. Hints that teach the move before they make it, a Learning Academy to go deeper, and 20 calm themes. Free, offline, and the same on every screen you own.
Pick a difficulty in the morning, finish it on the train. Skip a day and the archive remembers. The board stays quiet so the puzzle can be loud.

The launch trailer
One hundred quiet seconds.
The full launch trailer: real gameplay, the daily rhythm, hints that teach, the Learning Academy, and twenty themes — set to koto and falling blossom. There's no voiceover, so it plays just as calmly with the sound off.
What it actually looks like
Calm interface. Real screens.
Every shot here is from the real game on a real device. The board doesn't get redesigned for the marketing page — what you see is what you'll be holding.
Four puzzles. One quiet morning.
Easy, Medium, Hard, Extreme — four fresh puzzles every day, the same on every device. They're waiting on the home screen each morning; no setting to pick first, and a random board whenever you'd rather play without the streak on the line.
Big numbers. Soft edges. No friction.
Tap a number, tap a cell, undo if your thumb slipped. Pencil-mark notes for the corners, optional auto-check, and a timer that doesn't shout. Undo, Redo, Notes, Hint, and Erase sit to the side and stay out of the way.
A hint that earns the tap.
Stuck on Hard? The hint says exactly enough. First a nudge, then the technique's name, then the why — Naked Single, Hidden Single, X-Wing — and only then a button to apply it. The longest path is one tap; the best path is the one where you read the why.
Go deeper than basics.
A whole Learn tab: Controls & Shortcuts, The Basics, a Technique Academy of 40 lessons, and 39 guided drill sets. Follow the path, practice the pattern, then bring it back to the board — or jump into free Practice at any difficulty with nothing on the line.
Twenty themes. One quiet table.
Morning Paper, Sakura, Midnight Glass, Ocean, Forest, Zen Garden, and more — twenty hand-tuned light and dark themes (six free) that change the table, the numbers, and the mood together. Follow your system theme so it switches with the lights.
Progress that doesn't shame you.
An archive that remembers every daily you finished. A stats screen with best times per difficulty, current and longest streaks, and stars that fill in as you go — plus cloud save, leaderboards, and achievements where your platform supports them.
A few things you might miss at first glance
The quiet stuff that makes it stick.
Sudoku Haven wants you to come back tomorrow. The small things below are how it earns that.
Hand-graded across five difficulties, Beginner to Extreme. A fresh daily four, a full archive, and endless random boards — all offline.
Hints name the technique and explain the why before you apply. The Academy adds 40 technique lessons and 39 guided drill sets.
Twenty hand-tuned light and dark themes, six free. Follow your system theme, or pick one and stay.
Phone, tablet, desktop, TV, watch, and spatial — with cloud save, leaderboards, and achievements where supported.
