A brain teaser that blends number-grid logic with the vocabulary of word games — completely free, right in your browser. No account, no download, no nonsense.
What is Puzaku?
Puzaku is a word logic puzzle with a twist. Instead of filling a number grid, you fill it with letters — and those letters spell a hidden word. Complete the grid and you enter Phase 2: an anagram challenge where you unscramble the letters against the clock.
1
Fill the Grid
Place letters so every row, column, and box contains each letter exactly once — the same logic as a number grid, but with the letters of the hidden word. A category clue above the grid gives you a hint about the word.
2
Crack the Anagram
The timer keeps running. Unscramble the letters from the grid to spell the hidden word. Fastest fingers win.
It's part logic puzzle, part word game, part speed challenge. Work through unlimited levels — each brings a new word and gets progressively harder.
What Makes Puzaku Different
🧩
Two-Phase Gameplay
Most letter-grid games stop at the grid. Puzaku adds the anagram phase — the real challenge starts after the grid is done.
📏
Three Grid Sizes
4×4 Novice, 6×6 Classic, 9×9 Master. Each uses a different word length with its own difficulty curve.
🔥
Streak & Cheaper Hints
Play every day to build your streak. Every player gets a free hint bundle each game — your streak reduces the time penalty on any hints beyond that. Hit 30 days for minimum penalty.
⭐
Unlimited Levels
Each level unlocks the next with a new word. Levels get harder as you go — there's always another challenge waiting. Your progress is saved permanently.

Fully responsive — plays great on phones, tablets, and desktops. No app download required.
Same puzzle, same level, everyone.
Every player gets the same word at each level. Level 1 on 6×6 Medium is the same for you as it is for everyone else. Leaderboard times already include any hint penalties — so the fastest honest solver always comes out on top.
Free to Play
Puzaku is completely free. No account required, no paywalls, no features locked behind a subscription. Open the site and play. The game is supported by non-intrusive advertising that only appears when ads are available — you'll never see a blank placeholder.
No Account Required
Puzaku doesn't have logins. When you first play, a random anonymous ID is generated in your browser — that's your player identity. Your streak and best times are tied to that ID. If you want to move your progress to a new device, enable cloud save in ⚙️ Settings, copy your Save Code, and paste it on the new device.
