ZOK: The Alien Symbols
ZOK is the first mind warping memory game that is both lots of fun and incredibly challenging.
The object is to successfully finish all play levels -- in the lowest elapsed time. Each difficulty level delivers a larger-sized matrix of pyramid-shaped stone blocks with curious, etched, ancient symbols. Behind each symbol is a different positive or negative hidden number. You select symbols, three at a time, seeking three numbers totaling zero. When you complete all of the challenges for a level, you advance to the next difficulty level.
