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
• ~2800 puzzles built in — works fully offline
• Scoring based on German Scrabble letter values, with a pangram bonus
• Optional: tap a found word for its definition (from de.wiktionary.org — the only online feature, off by default)
• Light/dark mode selectable (follows the system otherwise)
• No tracking, no ads, no accounts, no Google services

The INTERNET permission exists solely for these Wiktionary lookups, and they are opt-in: unless you enable word definitions in the settings, the app never touches the network. Without a connection it says so in place of the definition; the game itself works fully offline.

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).
