SudoEarth
Read full descriptionHide full description
SudoEarth is a calm, zen-aesthetic sudoku game. No ads. No trackers. No notifications. Just sudoku, painted in watercolor across five real geographies ā Iceland, Kyoto, Tuscany, Norway, and Scotland. A SUDOKU WORLD TOUR Each chapter is a place. Iceland's aurora-lit fjords. Kyoto's bamboo grove. Tuscany's honey hills. Norway's cold-blue waterfalls. Scotland's misty highlands. Solve 30 puzzles in each chapter to complete the journey. 150 hand-tuned puzzles in version 1.0, every one verified to have a unique solution. MIRA ā A GENTLE COACH Stuck on a puzzle? Mira, your in-game guide, offers three-tier progressive hints ā direction first, then technique, only the answer if you ask twice more. The hint flow respects your pace: nothing is given before you've asked. Mira's tier-3 ground-truth gate means the answer is always correct, never an AI guess. WILDLIFE COLLECTION Each chapter has a hand-painted anchor wildlife ā Arctic fox, Japanese macaque, Tuscan owl, Norwegian reindeer, Scottish wildcat. Complete a level to unlock the painting. Walk into the Wildlife tab anytime to see your collection. DESIGNED FOR CALM SudoEarth's design language is rice-white paper, soft watercolor washes, italic serif chapter titles, hand-drawn ink icons. No saturated alarming red anywhere ā even the "out of hints" state lands on warm gold, not shouty red. The whole app is locked to light mode for now, deliberately, to match the airy notebook feel. OFFLINE-FIRST Every puzzle works offline. The rule-engine fallback means even Mira's hints work without a network ā your hints just route locally instead of through our server. Your puzzle progress is saved locally first, then optionally synced to your other devices via Apple Sign-in. PRIVACY-FIRST We do not track you. We do not sell your data. We do not show ads. SudoEarth uses Apple Sign-in's anonymous identifier ā we never see your name or email. Crash diagnostics use Firebase Crashlytics with no personal information attached. Full details at sudoearth.app/privacy. PREMIUM SUBSCRIPTION Free play comes with 3 Mira hints per day. SudoEarth Premium unlocks unlimited Mira hints. Two plans ā Monthly and Yearly. Both are auto-renewable subscriptions and renew unless cancelled at least 24 hours before the period ends; you can cancel anytime in iOS Settings ā your name ā Subscriptions. The yearly plan offers the best per-month value.

Verdict
The clearest difference is ads: SudoEarth at none against Glowfall's shown. SudoEarth also leads on update cadence (weekly vs every 4 months). On price, in-app purchases, device support and iOS requirement there is nothing between them.
