The cards are comprised with artwork or sprites from a group of 35 different Sonic the Hedgehog series games. The whole application is in Japanese.

Official Description
Sonic Tweet is nothing more than a free app for Twitter. SOJ is calling it a “Game-included Twitter Client”

The objective of the game (or app) is to collect 500 cards characters from Sonic’s history.

To play you have to tweet something using the app, and try to chain combos.

The tweet will be separated into single words, one of them will be randomly selected and assigned points. Apparentely words like 20th or Sonic will receive more points. Then, the app will connect that word with words from other users and generate a combo. The higher the score, the more powerful Sonic’s attack will become.

Tweeting short sentences or tweeting the same sentence many times won’t be made into combos.

By attacking Eggman and making his HP go to 0, you will receive a card.

To dash and attack Eggman you will have to wait some time, but this can be bypassed by using the cards you earn.

By defeating Eggman you will receive exp points that will be used to achieve higher levels. The maximum attainable level is 10.

It will be possible to exchange cards with other twitter users, however to do this both users will have to be using this app and be followers of each other. Card trading is limited to 3 times per day, up to 5 cards per time.

There are three types of rankings, and going up to the third place will earn you extra cards.
