Variable-dimension Sudoku from 4×4 to 25×25 — no ads, no tracking, no accounts, fully offline. One purchase forever.
Sudoku Atlas is a premium, distraction-free Sudoku app for iOS, Android, Windows, and Linux. It ships five grid sizes — 4×4, 6×6, 9×9, 16×16, and 25×25 — generated deterministically from seeds so friends can race the exact same puzzle. There is no ad SDK, no analytics, no crash reporter, and no account system; the app never makes network requests. Mobile is free to try (daily puzzle plus demo bank) with a one-time unlock; on Steam the complete game is $4.99 with no in-app purchases.
Sudoku Atlas will never run ads. It will never collect or transmit data about you. It will never introduce a subscription or lock previously free features behind a paywall.
These are not promises from a marketing team. They are structural decisions. There is no ad SDK in this app. No analytics framework. No account system. No server that knows you exist.

For the entire month of July 2026, the developer is personally donating all profits from Sudoku Atlas to UNICEF for the Venezuela earthquake response (quakes of 24 June 2026). Store payouts arrive after July ends; the donation receipt will be posted on the website once proceeds have arrived. This is a personal commitment by the developer, not a corporate campaign.
