Ultimate Flash SonicOr, Ultimate Flash Sonic, whatever you call it, it's still Sonic recreated in Flash. The 17-year old developer, Dennis Gid of Switzerland, claims no affiliation or sponsorship with Sega or Sonic Team, he is just a fan who loves Sonic games. And this remarkable version, his “Ultimate” Sonic, is his best to-date.

The game contains an extensive list of features including 4 playable characters: Sonic, Tails, Knuckles, and Cream, with 2 more to unlock. There are two modes of play, Main Game and Time Trial. Dennis has even included a password mechanism and a cheat code facility. Control is with the left and right arrow keys, space bar to jump, and enter pauses the game. To perform a spin dash: hold down arrow, press space bar, release down arrow.

Everything about this game is polished, right down to the initial selection menus with music and sound effect volume sliders. The mirror of the game linked here is hosted by the good folks at Newgrounds, an excellent site about media and games.

I am absolutely dumbfounded by this game. It's just superb. It looks to be just a pure Sonic game from back when the Genesis was the system to top during my younger years. Scary enough, things like this are now showing up on Nintendo-made handhelds; something I thought I'd never see happen. Next thing I know, my 10-year-old cousin will be trying to show me how to play the game. Now I feel old... I'm gonna go play more Sonic.

You can't enter in cheats, you have to win them, by beating the game with certain characters.

I think that's how it goes, because after my brother beat the game with knuckles, he got a cheat to go behind objects (well, appear behind them)making it harder

Getting a cheat as terrible as that makes me think they're all just visual effects

There are 2 new characters in Ultimate Flash Sonic. They're names are Amy Rose and Shadow the Hedgehog. And you can listen to the jukebox when you press the pause button. The jukebox let's you listen to the songs in the game even Amy's ending song by "Team Rose" and yes for the Boss music too.

Loved it, really good remake of Sonic, with all the features I like (ie.Slow Acceleration instead of the rediculous fast one as seen in later iterations and Grinding)

Hey i have seen this 1 b4... as i recall, sonic sucks, tails flies, knuckles climbs, and amy super-sucks. wtf? knuckles?

...If only this was even three zones...it WOULD be epic.

But it isn't. I've seen downloads with more work put in than this. 2/5 due to good potential, but wasted time. The reason it's 2 and not 3 is because I can't figure for the life of me how to actually get the characters' freaking special abilities to work...

CAUTION! THIS POST REVEALS ALOT ABOUT THE GAME
DO NOT READ OF U DONT WANT TO SPOILER

ok guys theres no super dark sonic.
no super sonic
the two unlockable characters are amy and SHADOW
knuckles cannot climb only real special abilitys on this game is cream and tails flying
rated down because of the lack of knuckles gliding abilitys and his climbing
rated down because of lack of amys hammer abilities
rated down because if the lack of shadows chaos control ability
other than that this is a preety decent game
code to unlock everything including the five cheats which are as follow

1:sonic run 2
2:tails follow
3:behind
4:big cheese
5:moon

effects of cheats

1: makes sonic signature circular feet spinn-thing activate (only with sonic)
2:tails flys behind ur character the whole time (dosnt work with tails)
3:makes your character walk behind all background objects (i do not reccomend turning this on)
4:makes cheese (the chao) bigger (only works with cream
5:makes your character jump higher and makes running different

the code is:

595313131313131

also people
THE OWNER OF THIS SITE DID NOT MAKE THE GAME
he is just showing us where a decent game is!
there is one extra unlockable which is:

the jukebox that makes it so when u pause the game u can change the music to whatever u like in the selection box

so yea this is completly accurate cause i completed the game not to long ago so if u get anything else up here (ie. codes info about super sonic and super dark sonic) it is wrong
thankyou and have a good day :P

Wow, I feel like JIG is getting spammed in these comments. If you have cheats/hints/spoilers

Use the spoiler tag, duh

I like it, Sonic was never that hard and this has some great nostalgia. The only problem with it being in flash like this is it's more vulnerable to lag and other effects that web browsers have.

Bravo to everybody who is dedicated to providing us with gaming nostalgia, whether it be through flash games like this, downloads and emulators (like DOSBox) or releasing a Sega Megadrive collection for the PS3 (who knew the 80s were so full of really bad fighter games?!).
