Wortmühle

Daily German word puzzle — 9 letters, one pangram, fully offline
新版本 1.2
The app now requests no permissions at all — the network permission is gone too. Word definitions ship inside the app and work offline; tap the Wiktionary link to read more in your browser.

The puzzle pool was revised: unwanted solution words are gone, along with proper names and incorrectly generated word forms. As a result the daily puzzles shift once — a puzzle you already solved today may be a new one after the update.
Wortmühle ("word mill") is a daily German word puzzle: build as many German words as you can from the nine letters on the 3×3 mill board. Every word must use the center letter, and every puzzle contains at least one pangram — a word using all nine letters.

Features:

• One new puzzle every day, with the last seven days replayable
• 2500 puzzles built in — one a day for almost seven years, fully offline
• Scoring based on German Scrabble letter values, with a pangram bonus
• Tap a found word for its definition — bundled, no network needed
• Light/dark mode selectable (follows the system otherwise)
• No permissions, no tracking, no ads, no accounts, no Google services

The app requests no permissions at all and never touches the network. The definitions ship with it: they come from de.wiktionary.org, are licensed CC BY-SA 4.0 and are shortened to the first two senses. Each definition carries a link to its Wiktionary page — tapping it opens your browser.

Note: the game and its vocabulary are entirely in German. The word list is derived from free sources (igerman98 word list, de.wiktionary, OpenSubtitles frequency data).
