Here is a Gameworks green Sonic themed Yoyo.
It's just an ordinary plastic yoyo that can be rebranded with any graphics or names a company desires. In this case, Gameworks the 'arcade & eatery' has branded it for themselves, and also Sonic. Gameworks functioned a little like an 'adult type' Chuck E Cheese but more heavily focused on video games, pool, bar, beer, tv-sports, and air hockey than kids stuff like Chuck's. However, it still did have tickets & a prize counter...and where there's video games and prizes you can bet companies are reaching for Sonic because he's so popular. Hence: this yoyo you could win.
Gameworks is gone now, but their nice modern style printed yoyo remains.
