It's laid out somewhat like a pinball machine, with a stand-up table and a LED text/graphic thing at the top that displays scores, art, etc.
During attract mode, you'll hear 2 songs: the original theme from the first Sonic the Hedgehog for the Sega Genesis/Megadrive, and the theme music from Sonic the Hedgehog 3.
The object of the game was to roll a token through a mechanism, into the machine and try to get the token to roll over one of the descending flashing lights, and you would get that many 'rings' for whatever light it landed on. It would then give you tickets based on your rings.

Unlike many Sonic-themed arcade machines, this was released in the U.S. by Leisure America and distributed by Sting International under license from Sega. It has been found in several malls. Notice that the light appears blue in the MFR shot, but then is actually red when seen in the arcade to the right.
