Hey folks!
A little while back I wrote an article about one of the best WPC games, Congo, for Seattle's Skill Shot pinball zine. The article was posted on their website recently, and I thought it would be of interest to at least some people on this forum. Anyway, take a look if you so desire! It covers a bit about the features of the game and has some tips on how to play the game for a high score, especially in tournament play.
