SudoEarth vs Theme Worlds

SudoEarth is a calm, zen-aesthetic sudoku game. No ads. No trackers. No notifications. Just sudoku, painted in watercolor across five real geographies — 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 — A GENTLE COACH Stuck on a puzzle? Mira, your in-game guide, offers three-tier progressive hints — 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 — 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 — 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 — 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 — we never see your name or email. Crash diagnostics use Firebase Crashlytics with no personal information attached.

Take a deep breath. Theme Worlds is the relaxing word game made for quiet moments. No timers, no lives, no pressure, ever. Swipe a wheel of letters to fill themed crosswords, and watch every word you spell bring a painterly world to life. Most word puzzles fill their grids with random words. Ours do not. In Theme Worlds the words belong to the place you are in: TIDE, PEARL and REEF beneath the Coral Reef, EMBER, MAPLE and HARVEST in Golden Autumn, LANTERN and STREET in London Mist. It feels like solving a tiny story instead of a grid. A CALM ESCAPE, BY DESIGN • Zen pacing: no clocks, no energy meters, no game over. Solve at your own speed. • More than 3,500 themed levels: 100 in every one of 28 worlds, plus 30 in each of 28 Day Trip towns. • Painterly scenery under a serene glass interface. Skies drift from dawn to dusk as you advance. • Music written for each world, so New Orleans sounds like New Orleans and Tokyo sounds like Tokyo. • Plays offline. No wifi needed on flights, commutes or quiet evenings. ELEVEN FREE WORLDS Sunrise Meadow, Redwood Fog, Coral Reef, Golden Autumn, Aurora Winter, Desert Canyon, Lavender Fields, Monsoon Jungle, Stormlight Coast, Observatory Peak and Midnight Library. Eleven hundred levels plus the daily puzzle, free forever. SIXTEEN PREMIUM WORLDS TO COLLECT Travel farther with one time unlocks you own forever.

Around the world: Neon Tokyo, Paris Lights, Kyoto Lanterns, London Mist, Rome Eternal, Sydney Harbour and Rio Carnival. And the deluxe Hawaii Island, a three act journey from dawn to torch lit night. Every premium world has bigger grids, its own music, and a friends leaderboard. TRAVELER CARDS Premium worlds award a Traveler Card every fifth level, twenty per world, and each Day Trip town adds six more. Finish a level flawlessly and the card turns gold. Complete a set for 1,000 coins, a gold set for 2,500, and a grand prize celebration. DAY TRIPS Every world has a small town beside it, and you earn your way in. Finish thirty scenes in a world and its ticket is yours, then the town opens for a small one time price: thirty more scenes and six Traveler Cards. Giverny from Paris, Rye from London, Kamakura from Tokyo, and twenty five more. WEEKEND GAMES Three small games open every weekend. Climb a word ladder, trace six hidden words in a grid, or turn over postcards to find every pair. Clear one for coins, clear all three for a bundle and a spare Day Trip ticket. FIND THE HIDDEN KEYSTONE A keystone word hides in the artwork of every level. Spot it for bonus coins. REWARDS EVERY DAY • A fresh daily puzzle with streaks, and Rest Days so one missed morning does not undo your progress. • Milestone chests and a bonus for finishing every world keep the coins coming. • Bonus words earn coins, so a big vocabulary is always rewarded. • Journey Album: a postcard for every world you complete. PLAY WITH FRIENDS • Invite friends with your six character code, and you both start with a bonus. • Game Center leaderboards for streaks, scenes and keystones. • A spoiler free share card for the daily puzzle. EARN YOUR WAY IN, OR PAY Nothing is locked behind money alone. Every world and every Day Trip town opens with coins you earn by playing, or with a purchase if you would rather not wait. Finishing a world earns roughly enough to open another. WHAT A PREMIUM WORLD GIVES YOU A third act: the scene carries on into night as you play, where free worlds close at dusk. Twenty Traveler Cards instead of five. Its own signature tile material. The ticket to its Day Trip town, included. A friends leaderboard, and a panorama when the set is complete.
