Sonic Jump

Sonic Jump is a 2005 vertical platform game developed by AirPlay and Sonic Team, and published by Sega for the digital distribution service Sonic Cafe, initially only available in Japan for mobile phones before being released in other regions in 2007. In 2012, the game was remade by Hardlight and also released for iOS and Android devices (later retitled Sonic Jump Pro), featuring updated graphics and new gameplay features, the remake received generally positive reviews for its extended length, being frequently compared favorably with Doodle Jump (2009). It was also a success, with the remake being downloaded nearly 9 million times by March 2013. Sega would later publish two sequels, both unrelated to each other, Sonic Jump 2 (2008) and Sonic Jump Fever (2014).

While games in the Sonic the Hedgehog series commonly involve running from side to side, Sonic Jump involves no running, but rather, Sonic jumping through the stages vertically to get to the top of the stage. The player controls Sonic by tilting the device left or right. Sonic jumps automatically, though a "double jump" move can be used upon tapping the touchscreen. Rings are collected throughout the stages, and protect Sonic from damage. In the original version, finishing an act with 50 or more rings would reward the player with a shard of a Chaos Emerald. In the remake, accumulated rings can be used to purchase further content in the game, such as items, upgrades, or additional playable characters. Players can "level up" by achieving certain objectives in each stage; increasing the player's level will allow access to new content for purchase.

The game contains two play modes; "Story Mode", which has preset stages with an end goal, and "Arcade Mode", which has randomly created stages that go on endlessly, with the purpose being to make it as far as possible through the stage.
