Sonic Speed a clever title for a card game

Sega’s main mascot is appearing in everything he can get his gloved hands on. After starring in a hoverboarding game Sonic decides to take a break and play some cards. Sonic Speed for cell phones in Japan is a digitalized version of the card game selling for the price of 100 yen ($1). The object of the game is to get rid of all the cards in your hand by placing your cards on top of the two center cards. You can only lose a card if it is 1 more or 1 less than either of the face up cards in the center. Other Sonic stars like Tails, Knuckles and Robotnik appear as in game opponents.
