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.

Parolix is a relaxing crossword word game you solve with one finger: swipe the letters on the wheel and every word you find drops into the crossword grid. Play offline, wherever you are, no internet connection needed. No lives, no game over: play at your own pace and train your brain. PLAY OFFLINE ⢠Levels work without internet from the very first launch: on the train, on a plane, on holiday. ⢠Your progress stays on your phone and syncs by itself as soon as you're back online. ⢠Only the Daily Grid, Daily Missions, the chest, leaderboards, Renovate and purchases need a connection. HOW TO PLAY ⢠Swipe across the letters to form a word, and it lands in the crossword. ⢠Find all the words to finish the level. Extra words outside the grid count too and earn coins. ⢠Stuck? Reveal a letter or a whole word, or shuffle the wheel whenever you like. ⢠From 3 letters at the start to a wheel of 9: an easy start that grows into a real word puzzle. NEW: YOUR OWL AND BONUS LEVELS ⢠After a few levels an egg hatches: name your owl and feed it with the worms you find in levels and chests. ⢠The more it grows, the more it helps: a small bonus to coins and points, plus the "Find treasure" and "Reveal a letter" skills. ⢠Surprise bonus levels on the map: Treasure, Ice, Blitz, Tower, Secret word and Star. YOUR EXHIBITION HALL ⢠Collect paintings piece by piece: pieces wait on the level map, hide in grid cells and come with daily missions. ⢠Three collections (the deep sea, the night sky and ancient giant trees), each painting with a true story. ⢠Finished paintings hang in your hall. Rehang them the way you like. ⢠Renovate: change walls and floors, add furniture, lamps, plants and curtains in six styles. EVERY DAY ⢠Daily Grid: one crossword for all players, one attempt and a daily ranking. ⢠Daily Missions: small goals with rewards. ⢠Daily streak: the reward grows every day in a row; a freeze saves a missed day. ⢠Daily chest: pick one of three. ⢠Reminders when your chest is ready or your streak is about to end. LEAGUES AND SEASONS Every level earns points in the season leaderboard. Climb from the Vanilla league to Master: the best players of the season get rewards. MORE ⢠Hundreds of crossword levels with steadily rising difficulty. ⢠16 animated themes: unlock them with levels, coins and seasons, plus a theme pack and Pro themes. ⢠Word history with definitions: look up any word you have found. ⢠6 languages: English, Italian, French, German, Russian and Ukrainian, each with its own dictionary. PAROLIX PRO A subscription: no banners or full-screen ads, video rewards without watching videos, and 3 exclusive themes. Love crosswords, word puzzles and brain teasers?
