Well this certainly looks interesting! I would have eaten this up as a kid! Sonic stars alongside two original characters other Sonics. It's unknown who Red Sonic and Yellow Sonic really were, or if they even had names. I'm pretty glad that we didn't get those recolored Sonic's though.

So what I gather is this is a unreleased Puzzle game that starred Sonic and his two different color brothers? It's interesting to say the least! Reminds me a bit of Sonic Eraser, another obscure puzzle Sonic game that actually did see a release but only on some airplanes in Japan if I recall correctly. The video doesn't seem to show up on your post though @Metallix.

Ok i cant see it. The video is taken down but i know that is just like a puyo puyo game but with sonic.
