the ultimate sonic flash game

back to the gameing

The very first Flash-based game in my site, here's Ultimate Flash Sonic! A game that any Sonic fan who grew up with a computer and internet will remember.
Since Flash stopped being a thing back in the end of 2020, this game is running through Ruffle, an open-source Flash emulator! Ultimate Flash Sonic should run flawlessly on Ruffle.
Anyhoo, the game should be ready to play. You need a keyboard to play this. If you've played 2D Sonic before you should already know the basics! Specially if you've played the Sonic Advance games, as this game is based in those. Your controls are the arrow keys and the spacebar.
Remember, the game uses a password-based save system. Keep note of your passwords.

And remember, enter "595313131313131" in the password section to unlock everything!
