The first spinner was apparently so successful they gave it a sequel! This is the "Sonic & Tails Spinner", and naturally it is more elaborate than the first. However, it works exactly the same as the Sonic Spinner, only there is a second "Tails wheel" to stop.
You put a coin in (most machines only need 1 quarter to run) and both Sonic and Tails start spinning, in opposite directions. You press the Sonic button first to make him stop spinning, and the number on the outside ring that he is pointing to is the first multiplier. Then, the Tails button activates. Tails points to the numbers on the inside ring. Your ticket amount is Sonics' number multiplied by Tails' number. This game is usually a very easy way to win a lot of tickets fast.

"Attract Mode"- when nobody is playing. Plays "Twinkle Park" music. Some machines may not do this, depending on how the owner programmed it.
Insert coin- "checkpoint" sound from Sonic Adventure.

While wheels are spinning- loops part of "Twinkle Circuit" from Sonic Adventure.
Win more than 10 tickets, and one of these character voice clips plays.
Tails- "Yeah!" OR "You did it!"
Sonic- "Cool!" OR "You got it!"
Knuckles- "Yeah!"
Win less than 10 tickets- No voice, and a "gloomy" music clip plays. Probably from Sonic Adventure, but unconfirmed.
Win more than 100 tickets- Sonic Adventure "Level complete" music, and a character voice clip.
These machines are harder to find than the Sonic Spinner because Sega stopped making them in 2003. One of them is located at Playland Arcade on the boardwalk in Rehoboth Beach, DE. Disneyworlds' Contemperary Resort has been reported to have one as well., but it IS confirmed to have a Sonic Spinner.

In the first photo, you could tell there was art on the cabinet. In the gallary is a photo to show you exactly what's on it. The whole flat 'counter' part of the machines have the traditional Sonic Adventure 1 art on them, of each of the characters. Big, Eggman, Knuckles, E-102 Gamma, Amy Rose and even a Neutral Chao appear. Sonic and Tails are near the front, and also on the spinner buttons. On the buttons, the same graphic is used as is on the ReSaurus "stickers" that came with their action figures. Between the speakers is your score readout, and the little line under each button is the instructions. (Basically push Sonic first, push Tails second)
