What’s new
New settings (gear icon): system/light/dark theme and word definitions. The online lookup via de.wiktionary.org is now opt-in and off by default — the app never touches the network unless you enable it.
Quick answer
Daily German word puzzle — 9 letters, one pangram, fully offline
F-Droid repository metadata
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).
