About Puzaku

A daily brain teaser that blends the logic of Sudoku with the vocabulary of word games — completely free, right in your browser.

What is Puzaku?

Puzaku is a unique puzzle game that puts a twist on classic Sudoku. Instead of numbers, you fill the grid with letters. But here's the catch: those letters spell a hidden word. Once you complete the grid, you enter Phase 2 — an anagram challenge where you unscramble the letters against the clock.

It's part logic puzzle, part word game, and part speed challenge. Every day brings a new puzzle, and there are unlimited levels for players who want more.

What Makes Puzaku Different

🧩

Two-Phase Gameplay

Most word sudoku games stop when you fill the grid. Puzaku adds an anagram phase — the real challenge starts after you complete the grid.

📏

Three Grid Sizes

4×4 for beginners, 6×6 for the daily workout, 9×9 for masters. Each uses a different word length with its own challenge.

🔥

Daily Streaks

Play every day to build your streak. Miss a day and it resets. Simple, addictive motivation to keep coming back.

⭐

Unlimited Levels

Finish today's puzzle and Level 2 unlocks with a new word. Keep going — there's always another puzzle waiting.

🏆

Weekly Challenge

The same puzzle for an entire week. Play it multiple times, beat your best time, and compete with friends via shared results.

💾

Auto-Save

Close the browser mid-puzzle? No problem. Your progress is automatically saved and waiting when you come back.

🌙

Dark & Light Themes

Play in whichever mode suits your eyes. Your preference is remembered across sessions.

📱

Works Everywhere

Fully responsive design that plays great on phones, tablets, and desktops. No app download required — just open the browser and play.

Same puzzle, same day, everyone.
