“Ultimate Flash Sonic” is a fan-made Sonic game that tries to recreate the excitement of playing officially licenced Sonic games. The goal is to collect rings and avoid running into opponents while moving at a high speed, just like in the official games. Because of the good controls and the presence of various characters from the Sonic universe, the game is regarded one of the better Sonic Flash games.
Internet browsers that support Adobe Flash are required to play the game. Players manipulate Sonic with the arrow keys and make him jump with the space bar using the keyboard controls. Sonic’s spin dash may also be done by holding down the down arrow and pressing the space bar. By pressing the enter key, the game can be paused at any time.
