Sonic the Hedgehog Mobile, also referred to as simply Sonic the Hedgehog,[1] is a port of the 2005 Sonic Cafe version of the original Sonic the Hedgehog. It was released to J2ME mobile devices through the Sega Mobile service offered by Sega. It later came bundled with certain Panasonic cell phones in Europe and Japan.

Depending on the service provider, the game is either provided as one full game or in two parts: Sonic the Hedgehog Part 1 and Sonic the Hedgehog Part 2. Part 1 only provides the first three levels of the game while Part 2 contains the final levels.

There has also been a second, not as widely known version of the game for Verizon and AT&T phones that has everything that the original version did, except has strangely removed all of the sound effects.



This port of Sonic the Hedgehog closely mimics the Sega Mega Drive version, but some features have been removed, most notably the Special Stages. Once the player leaps into the Giant Ring, they are automatically rewarded with a Chaos Emerald. Enemies no longer release small Animals when defeated. Graphics have also been re-sized and the palette of flowers at Green Hill Zone is different. Several graphics that were unused in Sonic the Hedgehog remain hidden in the port including the famed Marble Zone UFOs. Some of the levels have minor tweaks, such as the removal of a see-saw from the Egg Spiker encounter, and the removal of a crusher from the Final Zone boss room.

Despite the numerous removals, some things were added to the game to make it easier, such as unlimited continues and a save feature. A scoring system was also added and the top five scores will be saved, alternately they can be uploaded to an online high score ranking. Three levels of difficulty were also added: very easy, easy and normal. Very easy mode is completely lacking of enemies and only the boss of the Zones are present.
