RuneWords is a word-puzzle adventure with two ways to solve the same crossword. Swipe letters on the wheel to build words, or switch to Clues and answer Across and Down prompts. Solved words stay in place when you change modes. CAMPAIGN Explore 1,000 bundled boards across 10 realms. Find bonus words for extra coins and use optional rune hints when you want help. If you used hints on your first clear, replay a campaign board without them to earn its rune-free crown. The crown bonus is awarded once per board. Game Center achievements are optional. DAILY PUZZLES Play 90 authored daily boards, scheduled from October 8, 2026 through January 5, 2027 (UTC). The schedule is separate from campaign progress, bundled for offline play, and gives everyone the same puzzle for each UTC date. RuneWords shows the next reset in your local time. Replay past dates from the archive for practice without another daily reward. FRIEND PUZZLES Share a specific campaign or daily board by link, or choose Friend Puzzle from the menu and enter its code. A friend plays that same board with free hints; challenges award no coins and do not change campaign progress. Friend puzzles require RuneWords 1.2 or later. If you need to install or update RuneWords, do that in the App Store, then open the shared link again or enter its code in the app. HINTS AND PURCHASES RuneWords is free to download. Ads may appear during play. Optional purchases are Small, Medium, and XL Coin Packs, The Starter Bundle, and Remove Ads. Coin packs add spendable coins and cannot be restored through Apple. The Starter Bundle is a one-time coin offer. Restore Purchases can recover Remove Ads and recognize a Starter Bundle you already bought; it does not refill spent coins. Prices are shown in the Store before you buy.

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 — 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. 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 — 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 → your name → Subscriptions. The yearly plan offers the best per-month value. REQUIREMENTS - iOS 26 or later - iPhone or iPad - Optional: Apple Sign-in for cross-device sync LINKS - Privacy Policy: https://sudoearth.app/privacy - Terms of Service: https://sudoearth.app/terms - Support: support@sudoearth.app Auto-renewable subscription terms and conditions: SudoEarth Premium subscriptions automatically renew unless turned off at least 24 hours before the end of the current period.

Verdict
The clearest difference is ads: SudoEarth at none against RuneWords's shown. On price, update cadence, in-app purchases and device support there is nothing between them.
