Nags is a unique game from Williams with two interesting features -
It is one of a small handful of horse racing themed games that Williams made with a horse racing unit with six horses that can move independently along a track, until one finishes.
This game is also the only game from the 'big three' manufacturers that had a rotating platter of six pop bumpers. Each bumper hit would advance one horse toward the prize.
25 cents on 'Stinky' for me!
