Design for focus
No flashing rewards, no frantic timers. A calm dark interface keeps your attention on the puzzle, where it belongs.
About the studio
Sangeetha Softwares is an independent mobile game studio. We started with a simple idea: puzzle games can be calm, beautiful and genuinely good for you.
Most mobile puzzle games are built to hold your attention as long as possible. We build the opposite — games that respect your time and reward a few minutes of focused thinking each day.
That philosophy shaped everything about SudokuZen: a calm dark theme, no punishing timers, gentle hints, and progress systems that measure improvement instead of just playtime.
The idea
Sudoku is one of the world's most-loved logic puzzles — perfect for a daily brain workout. We set out to make a version that is genuinely helpful to learn from.
The build
We wrote every puzzle generator, every animation and every screen in Flutter, obsessing over feel — from the satisfying fill sounds to the golden glow when you solve a row.
SudokuZen
SudokuZen launches with 500 handcrafted classic levels across five difficulties, a Daily Challenge with streaks, and unlimited quick games — all free, all offline, with optional ads to fund development.
Next
We're already exploring new puzzle genres in the same spirit — thoughtful, calm and quietly addictive.
No flashing rewards, no frantic timers. A calm dark interface keeps your attention on the puzzle, where it belongs.
Stars, streaks and a brain profile turn daily practice into something you can watch yourself get better at.
Your progress stays on your device. No accounts, no profiles on our servers, no personal data collected by our apps.
SudokuZen is our first release — a daily brain-training ritual in a calm, dark package.
