The mobile version of Crash Nitro Kart is a simple racing game released for old Java-enabled phones. Besides one or two similarities with the console game, it's mostly a quick distraction from a bygone era when phones had much more limited technology.
The game uses basic 2D graphics, and other than the Crash Bandicoot 3 theme playing in menus, the game is mostly silent besides some bleeps and bloops.
There are 2 modes to choose from: Single Race and Tournament. Single Race is self-explanatory, and Tournament lets you drive through all 4 tracks of an environment in succession, accumulating points based on your position. Get more points than everyone else and you'll win the tourney, unlocking a new environment in the process. There is a total of 3 environments: City (based on Android Alley), Beach (based on Inferno Island) and Castle (based on Clockwork Wumpa).
Each track is very simple with small allusions to the console version: there are turbo pads, holes to avoid, and 4 different kinds of power-ups. As for the playable roster, you can race as either Crash, Cortex, Coco, or Crunch, and each character has unique stats.
