Doku - Sudoku with Friends

By Math Game House LLC

Open iTunes to buy and download apps.


DOKU is the Sudoku-inspired App that you've been waiting for to play with your friends.

1. Doku Duel : real time versus mode via Game Center.

2. Dokugram : share finished puzzle via Facebook or email to engage friends in virtual duels. Tweet SOS when you are stuck.

3. No more barrier for number-phobes. Unlock all gorgeous skins that include traditional numbers and gemstones.

4. Unlimited on-board generation of fresh puzzles.

5. Cloud-synced stats, Game Center leader boards.

6. Most ergonomic user interface including the innovative "Tap 'n Rub" action mode

7. Calm, atmospheric soundscapes, smartly managed music loops and 3rd party music patch-through

Distinctive features of Doku as the solo sudoku

* Multiple skins based on number or symbols. Those of you number-phobes may finally join the ranks of sudoku masters.
* Intuitive, time-saving input methods (innovative direct-input on iPad!), non-repetitive musical and ambient sound effects.
* Cloud-synced stats management across multiple iOS devices.
* On-board generation of fresh puzzles (virtually infinite, unique puzzles at six difficulty levels)
* Full Game Center integration. Global ranking systems based on the Doku Index and the average time for each of the six difficulty levels and across the board ranking.
* Posting SOS (with puzzle image) to twitter; stats-boasts to Facebook
* Beautiful sound landscapes and non-intrusive background music

Game-changing Features to start the Global Doku Party

YET, we didn't stop there. Check out these innovative features that are new to the Sudoku community:

* Chess has speed-chess. Why not for sudoku? Play a time-race on the shared puzzle in real-time with an invited friend or random opponent via Game Center.
* Post a finished puzzle (along with your moves-history) as a "Dokugram" to "share" with your friends. By "sharing", we didn't mean just sharing the puzzle…

The "Dokugram" brings these ground-breaking features:
* email the dokugram to friends (and yourself) so that they can play the same puzzle against you (in real time, as Doku will reproduce your moves faithfully in the duel mode!)
* post the dokugram to your Facebook timeline so that all your facebook friends can tap on it to play the same. Each players stat will automatically accumulate in the original post's comments. So, finally, a meaningful way to party with your facebook friends and figure out who is the smartest!

Invitation to the Global Doku Party

Surprise yourself with the visual cognitive skill that had been locked inside. Who, among your friends, is the smartest? Who is the wicked one in a duel? Who turned out the most loyal in your times of need? Let Doku help you discover the true nature of your friendship.

You are invited to join the party,
If you love puzzle, but were afraid to try sudoku because you simply hates numbers
if you were getting tired of those social network apps that forgot that you have a brain
if you are a veteran Sudoku player and were looking for a fresh challenge

Best Sudoku app I've tried

I've played many Sudoku apps. Some are better than others; however, this is the best Sudoku app I've ever tried. It allows you to touch the square first and then your number/color selection. Or, if you prefer, you can touch the number/color selection first and then the square where you want to place it. Awesome app! Good job!

I hope the number font will be changed in the future to be more legible. It is difficult for me to distinguish between 3s and 5s.

I love this game.

I like the interface, the different ways to place the numbers/colored blocks, and the difficulty levels. Also excited to try the duel mode, but am trying to practice with solo mode in order to improve my time. It's a good game, I would recommend it. Hope you all like it too. :)
