Sonic Jump 2 is a mobile phone game released as part of the Sega Mobile service offered by Sega. This game is a sequel to Sonic Jump. Like the first, Robotnik is out to destroy the planet, and to stop him, the player as Sonic must jump from platform to platform, rising up the screen to the top. If Sonic hits the bottom of the screen, he loses a life - collecting 50 Rings gains one back. There are 7 levels of increasing difficulty. New to this game is a fragment of Chaos Emerald in each level - to collect it, you must finish the act with at least 50 Rings.
