CONGO is fun, audio cranked is great. Dot matrix for nasty goriilas and snakes coming from the 3 doors u chose from in video modes is way cool. Gorilla on backglass (the nasty one) is drawn very well.
The right volcano lock ball shot is not easy and makes it fun/challenging. In great condition, the CONGO is a looker with Leds etc. Playfield has a Indy Jones feel down near the flippers. Congo is a surprising gem (no pun intended- Diamonds !.lol)
Not a real known game, but people are drawn to it cause they have never played it. Surprisingly unique. Definately worth some games, as its not easy. Subway gorilla playfield also a nice touch. more so a unknown game versus under rated.
