Quadrax is an excellent logic game that was the best-selling title in Slovakia and Czech Republic in 1996. The game is actually a PC conversion of a 1994 Spectrum ZX game of the same name, designed by David Durcak. The goal is for two adventurers to make their way through each level on their way to a rumored treasure. Along the way, they have to negotiate various traps and other obstacles. You control both characters, who must sometimes co-ordinate at the right timing to succeed, similar to the vikings in The Lost Vikings...
