Ultimate Flash Sonic is a fan-made Sonic game that seeks to replicate the gameplay experience of officially licenced Sonic games. Similar to the official games, the objective is to collect rings and evade adversaries while moving at high speed. The game is regarded as one of the best Sonic Flash games because to its responsive controls and inclusion of characters from the Sonic universe.
The game can only be played in web browsers that support Adobe Flash. The keyboard controls allow players to move Sonic using the arrow keys and make him jump with the space bar. The spin dash can also be performed by holding the down arrow and pressing the space bar. You can pause the game at any time by pressing the enter key.
