## Description

Gemdoku is Sudoku, played with gems instead of numbers.

The rules you already know: fill the 9x9 board so no gem repeats in any row, column, or 3x3 box. Nothing about the logic changes. What changes is how it feels to look at — nine distinct gems your eye can scan without reading, on a board built to be calm rather than loud.

A DAILY PUZZLE WORTH RETURNING TO

Daily Spark is one date-seeded board a day, the same puzzle for everyone who plays it. Solve it and your streak grows. Miss a day and you keep every gem, every level, and every best time you have earned.

Prefer to play at your own pace? Start a standard puzzle at Easy, Medium, Hard, or Expert whenever you like.

YOUR SOLVES BECOME A GARDEN

Every completed board feeds the Gem Garden. Gems unlock, then polish through levels as you keep solving, so a month of quiet puzzles adds up to something you can actually see. Achievements track the harder stuff — solves with no mistakes, solves with no hints, daily streaks, and breadth across difficulties.

BUILT FOR A CALM SOLVE

- Notes mode for candidate marking, with matching gems highlighted as you select
- Undo, a running timer, and mistake tracking
- Hints when you want them: 3 free on Easy and Medium, 2 on Hard and Expert
- Relaxed mode, which holds back conflict highlighting until the board is full
- Your puzzle saves itself — leave mid-solve and pick it up again from the home screen

PLAYS THE WAY YOU NEED IT TO

- A high contrast board option: stronger borders, bolder cell highlights
- Light and dark themes, or follow your system setting
- Full screen-reader support — the board announces itself as a 9x9 grid, cells describe their state, and every control has a purpose-oriented label
- Honours your system reduced-motion setting
- Adjustable music and sound effects, independently

PROGRESS THAT FOLLOWS YOU

Your puzzles, history, and settings sync to the cloud automatically — no account, no email, no sign-up. Reinstall and your garden is still there.

Leaderboards are opt-in by nature: pick a display name if you want to appear, or don't.

ABOUT ADS AND PREMIUM

Gemdoku is free, supported by ads, and deliberately conservative about them. No full-screen ad interrupts you mid-puzzle on its own: the only uninvited one appears after a board is finished, never on your very first solve, and never more than a few times a day. If you want an extra hint beyond your free ones, you can choose to watch a short video for it, up to three per puzzle.

Gemdoku Premium is a one-time purchase that removes banner and full-screen ads and adds bonus hints once your free ones run out. There's no subscription and nothing else is locked behind it — every puzzle, difficulty, gem, and achievement is available without paying.

Gemdoku is intended for players aged 13 and over.
