Word Sudoku swaps numbers for letters. New puzzle every day, global leaderboard, four game modes. Play free on Android.

Hi everyone! 👋 I'm the maker behind Word Sudoku. I’ve always loved the pure logic of classic Sudoku, but I also really enjoy the daily ritual of modern word games. I wanted to see what would happen if I combined the two—swapping out numbers for letters to give a fresh twist to a familiar grid. The hardest part was making sure the logic held up while keeping it fun. That's why I built four modes: a global Daily Challenge, a progression Level system, Practice, and my personal favorite—Wildcard mode, where you can type in any word and the board builds itself around it. It’s completely free to play on Android. I’d love for you to try out today’s daily puzzle and let me know how the letter-based logic feels compared to numbers. All feedback is hugely appreciated! 🙏

The letter twist makes the puzzles feel fresh even if you've played regular sudoku a hundred times. Ranks give me a reason to stick around past the first puzzle.

would love an offline mode so i can play on the subway without losing my streak. also, can you add a hint system for the harder modes

Loving the letter twist so far. One thing that would help me a lot: a small dictionary lookup or hint button for any letter I forget, maybe limited to a few uses per day so it does not kill the challenge.
