Sonic Cafe was Sega's mobile phone game service in Japan. For a fee of ¥315 a month (after tax), the user received access to the entire library of currently available games and could download them as many times as they wanted to. The service was available on NTT DoCoMo's i-appli phones.
The service was only available in Japan, however, select few of these games became available in the United States and Europe on the Sega Mobile service.
The list of available games was relatively large, with a number of ports of classic games (such as Sonic the Hedgehog for the Mega Drive), along with several new ones. The list below contains only the Sonic related games that had been released.
