When you are playing with our online games, the first step is to Login. Your iPhone/iPod Touch hooks up to Twitter (or Facebook) using its API and SOAP authentication. This is it to ensure you are who you say you are and gives us the solution not to save your Twitter or Facebook login names and passwords to our server. Please note that we do not store personal informations.

Your iPhone gets to Twitter and Facebook through secure connections using SSL technology. Your Twitter creditentials are handled in a safe way. Due to the choosen technology you can play online games only with Twitter or Facebook account holders: Sign Up to Twitter here

After the Login we must find your friend who you want to play with. He or she may be connected to a cellular network, or hides behind a firewall and has a wifi connection. Your friend may be 10,000 miles from you but we try to find him/her for you anyway. Do not forget that your opponent must know in advance that you want to play online sudoku.

During these steps, our SQL Database server is also connected to provide instant game messages between the two devices and to keep track of scores and rank. You can receive and send messages to check if your opponent is available or not. You will receive messages from our game server as well. The connection is noticeably faster over Wifi, but we’ve optimized the program to work fast over 3G and even Edge.

Our sudoku engine can produce over 6 quintillion (6 * 10^18) unique games. That means you could play for 32 billion years if you play a new game every second. If you achieve that feat, shoot us an email and we’ll give you a special prize.

Theorically we can connect unlimit number of gamers to the master's table. Master is who starts the session and invite his/her friend(s) to the table. We believe that you invite only one friend to a session. In practice, there may be many devices all running our application, but the supported heads-up game connections (ie. sessions) will always be established through paired devices. We can serve unlimited number of separated sessions.

Sudoku Social is compatible with Sudoku Vario.

Twitter is one of those websites with very little room for functional nuance. Its limit of 140 characters per post forces users to be simple and to actually be useful. Others see unbridled freedom inside and embrace it like a poetic device.

Regardless of how you feel about it, Twitter is a great place to start your online experience.
