Everything you need to know about playing Puzaku — plus a few tricks to sharpen your game.
Frequently Asked QuestionsPuzaku is a free browser-based word logic puzzle game. Each puzzle has two phases: first you fill a letter grid using logic (similar to how a number puzzle works, but with letters), then you unscramble an anagram to discover the hidden word. It works on any device with a browser — no download or account required.
No. Puzaku saves your progress locally on your device. You can play indefinitely without ever signing up. If you want to back up your stats or appear on the leaderboard, you can opt in to cloud save in ⚙️ Settings — but it's entirely optional.
Enable Cloud Save in ⚙️ Settings on your original device. This gives you a Save Code — a unique string of characters. On your new device, go to Settings, scroll to Restore Progress, paste your Save Code, and your stats will be restored.
Levels is the main progression mode. You work through an ever-growing set of puzzles, one at a time. Each level has a unique word, and your progress is saved permanently. Completing a level also counts toward your daily streak.
Weekly Challenge gives every player the same puzzle for an entire week (per grid size and difficulty). You can replay it as many times as you like to beat your best time. Weekly solves do not count toward your streak.
Your streak increases by one each day you solve at least one level in Levels mode. If you miss a day, it resets to zero. Playing on the same day twice doesn't double-count. The Weekly Challenge does not affect your streak — only Levels mode counts.
Maintaining your streak unlocks more free hints over time. See the tips section below for the full streak rewards table.
Every game starts with a set of free hints based on your current streak and grid size. Once your free hints are used, you can watch a short ad to earn two bonus hints. If no ad is available, you still get the hints for free.
Beyond that, additional hints are available with a time penalty added to your solve time. The longer your streak, the smaller the penalty. For full details, see the How to Play page.
Giving up during the grid phase will reveal the solution and unlock the next level — but it won't save a time, won't update your streak, and won't record a personal best. Your streak stays at whatever it was before the game. Think of it as a learning tool: you can study the solution and try again fresh on the next level.
Each hidden word belongs to a category — animals, nature, food, science, emotions, sport, and more. The category is shown as a clue during gameplay to help you narrow down the anagram. After solving, it also appears as a badge on the completion screen. You don't choose or filter by category — it's purely a helpful hint.
Yes, completely free. Puzaku is supported by occasional ads — a banner on the home screen and a short video when you need bonus hints. There are no paywalls, no locked levels, and no premium currency. Every puzzle is accessible to every player.
By default, nothing leaves your device. Your stats, progress, and a randomly generated player ID are all stored locally. If you choose to enable cloud save, your stats are sent to our server so you can restore them later. The full details are on our Privacy page.
We'd love to hear about it! Drop us a message at hello@puzaku.com with details about your device, browser, the grid size and difficulty you were playing, and what went wrong. Screenshots are always helpful. Your Player ID (bottom of Settings) can help us investigate, but it's optional. See our Contact page for more details.
The grid works like a number logic puzzle but with letters. Each letter appears exactly once per row, once per column, and once per box. Start with rows, columns, or boxes that already have the most letters filled in — these have fewer possibilities and are easiest to solve by elimination.
On 6×6 and 9×9, look for two cells in the same row or column that can only contain the same two letters. Once you identify a pair like this, those two letters can be eliminated from every other cell in that group — often unlocking several other cells in one go.
If you're confident about a cell, mark it with ✓ Sure as a visual anchor. If a cell could be one of two letters, mark it with ? Maybe and move on. When you solve another cell nearby, you'll often rule out one of the options automatically.
The category shown above the tiles is your biggest ally. If the category is "animals" and the letters are T, G, I, E, R, the answer is a lot more obvious than if you were staring at random letters. Always read the category first.
If you're stuck, try pronouncing the letters or rearranging them mentally into common English patterns. Words love combinations like TH, CH, SH, ING, TION, and IGHT. Start from likely beginnings or endings and work inward.
As you fill in the grid, start mentally rearranging the letters you've placed. By the time Phase 2 starts, you may already have the answer — or at least a strong guess. This is one of the biggest time savers experienced players use.
Don't rush — speed comes from recognising elimination opportunities faster. The more puzzles you solve, the more instinctive the logic becomes. On Easy, use the instant rejection to your advantage: try likely letters quickly and let the game confirm or reject them.
4×4 Novice — ideal for quick sessions and learning the mechanics. Games typically take a few minutes and there are only four unique letters to manage.
6×6 Classic — the sweet spot for most players. Complex enough to be satisfying but short enough for a coffee break. Six letters also make the anagram more interesting.
9×9 Master — the full challenge. Nine unique letters mean a much harder grid and a tough anagram. This is where experienced puzzle players will find the most depth.
Free hints don't carry a time penalty, so use them without guilt when you're stuck. But once you move into penalty hints, each one adds time to your final solve — which matters if you're competing on the leaderboard or chasing a personal best.
A good rule of thumb: use free hints early to keep momentum, then try to power through the last few cells on your own. The satisfaction of a clean solve is worth the extra thinking time.
The longer your streak, the more free hints you start each game with. Every milestone improves every grid size.
| Streak | 4×4 | 6×6 | 9×9 |
|---|---|---|---|
| 0–6 days | 2 | 3 | 3 |
| 7–13 days | 3 | 4 | 4 |
| 14–29 days | 3 | 4 | 5 |
| 30+ days | 4 | 5 | 6 |
To appear on the leaderboard, enable two things in ⚙️ Settings: Cloud Save (so your times are stored online) and Leaderboard Visibility (so other players can see your times). Both are off by default to respect your privacy.
The leaderboard shows the best times for each grid size and difficulty. Hint usage is tracked — a clean solve always looks better than a hinted one.
The Weekly Challenge gives everyone the same puzzle for seven days. Since you can replay it as many times as you want, the key is learning from each attempt. Your first run reveals the word and the general grid pattern — subsequent runs are about optimising your route through the grid.
Try to remember which cells gave you trouble on the first attempt. On your next try, tackle those tricky cells early while your mind is fresh. Many players shave 30–50% off their first-attempt time by their third or fourth try.
Puzaku is meant to be a relaxing daily brain exercise. There's no penalty for taking your time, and every puzzle has a solution. Keep your streak alive — even a quick 4×4 Easy solve on a busy day counts. Trust the logic, use the clues you're given, and enjoy the moment when everything clicks into place.
