"I had not thought that a word game could be so beautiful. Beautiful to see and hear, but also the stern, unyielding beauty of logic." - Matt Thrower, GameZebo

"Another week, another new word game., if anything, better than Letterpress." -- Shane Richmond, The Telegraph

"COMPELLING" ... "It’s a very simple idea, but a good one. QatQi offers a different type of word game challenge, and flourishes for it. All the better for being free to download, and exceptionally easy to dive into for short or long sessions." - Jennifer Allen, 148Apps

"Just when you think there can't be much more new ground to be broken in the word-games genre, along comes something like QatQi with an inventive take on letter-based puzzling." - The Guardian

Lose yourself in the world of QatQi (pronounced “cat-key”), a gorgeous and meticulously crafted word game that pleases the senses and tests the limits of your lexicon. Frustrated with the lack of innovation in other word games, indie designer Chris Garrett developed QatQi to freshen up the genre with never-before-seen gameplay, an elegant interface, dazzling art, and otherworldly music that changes as you play. In a word, it’s INSPIRED (161 points.)

QatQi offers more than just laying down tiles and reaping the rewards. Game puzzles form a “map” for players to explore, uncovering bonuses and avoiding barriers as they link letters together. It’s easy to learn, but offers a new kind of strategic depth for the genre. Bolstered by robust statistics and enticing social features, QatQi is a complete package for word game lovers eager for something new.

Beyond the innovations in gameplay and scoring, QatQi is an audiovisual tour de force with art and music that can be appreciated even without words. The game’s puzzles will have you racking your brain, but its ethereal aesthetics will leave you in a state of zen.
QatQi features:

Novel “map” mechanics — Explore each puzzle by laying out tiles to spell words across increasingly intricate rooms and corridors. Special squares offer big bonuses, but require some smooth wordsmithing to reach.

Smart, scaling difficulty — Sunday levels can be brutal, but QatQi eases players in with simple puzzles and an intuitive tutorial. If you’re backed into a corner — sometimes literally — take another try with an Undo.

Size up your spelling — Compare your performance with players in your city or across the globe using QatQi’s cater-made scoring system. Post automatically and view full breakdowns — all without disruptive logins or passwords.

Vaunt your vocab — When you top the charts in your area or drop a high-scoring word like MOUNTAINEERING (461 points), QatQi will make a personally framed screenshot for you to boast over Facebook, Twitter, email or SMS — all from within the game.

Data to die for — To boost your scores, explore a beautiful interactive stats page that provides key metrics after each puzzle. Even as a novice word-slinger, QatQi’s granular breakdowns will give you something to aim for.

Fresh content, always — QatQi offers new levels every day of the week, scaling up in difficulty from Monday to Sunday. Past levels are archived for access anytime.

Audiovisual bliss — Artist Kun Chang, who created the artwork for the hit game Osmos, lends a striking sensibility to the game board and menus. Complementing the looks is an original, spectral score that builds in complexity as you move through more difficult puzzles.

Continuously raises level of 'inner' competition

My personal use of this 'app', and time spent engrossed in its obvious and subtle challenges compel me to rate QatQi as one of the very best 'brain games' available. I subscribe to 6 (or more- I lose count😂) 'ed' related/cognitive training 'apps'. Lumosity, Elevate, Peak, Brainwell, Mindgames, and- most recently- Neuron... (cannot recall exact title) all offer enjoyable, intriguing 'strengths'.
Yet- consistently, for over 2 years now- I access and play QatQi because the 'rules' remain simple, the visualization is beautiful and engaging, the challenge for success is attainable and rewarding, and the progress in language expression, spelling, context, and usage is real, and relevant.
As a career special educator (42 years of teaching, with an earned Ph.D. In the 'field'), I highly recommend this game to all language 'learners' who love the idea of self-improvement in spoken/written English.
To the 'creators'...kudos!
Please attend to other critiques/comments related to random letter assignation, difficulty- at times- in building 'longer' words, and access to easier 'restart' if truly perplexed near 'end game'. Attention to these worthwhile suggestions- I agree- would further popularity.😘
A wonderful application! Thank you.


Beautiful and enjoyable

This game is a guilty pleasure. It is extremely clever in conception and beautiful in execution. I like many features: the various levels, the amazing power tiles, the mysterious layout which takes shape as you explore, the rising values as you get further on. It's a challenge to build when you don't know what's coming next, and the undo and restart systems are clever ways to let you try things out. Of course, that means you can waste hours on a game that otherwise might take fifteen minutes. And it's just so aesthetically pleasing! I hope that it is a financial success so that it can continue.

Great game with poor usability

I'd love to give this game five stars. It plays well. The interface is beautiful. The problem is the pretty interface makes it really hard to play on an iPhone 5s. The "play" buttons to start a game are hard to hit, and it frequently misplaces letters then wants me to spend an undo to put it where it was supposed to have put it in the first place.

The game is also marred for me by a bunch of inscrutable rules that don't add anything to the game for me and I don't see what it's doing for the developers either. What's up with having different games locked based on which previous day's puzzles I have completed? It's not a level thing. It's not a progress thing. I just spin the stupid dial until I find one at the level I want to play and that happens to be unlocked.
