ENIGMA
"5 out of 5" rating!!! MacUser Magazine/Ziff Davis

A code breaking game, like the classic Mastermind,  Enigma provides a mental workout while 
offering hours of entertainment. 

The goal of the game is to break all of the codes and thus open the Enigma Briefcase. And what is inside the Briefcase? No one knows: perhaps a fortune in diamonds or directions to King Solomon's Mine; maybe the secret of eternal life or only a change of underwear. You'll have to open the Enigma case, if you're able, to find out!

While Enigma challenges your logical thinking, reasoning ability, and problem solving skills, it does so with a sense of humor. Strange little adversaries will attempt to thwart your code breaking efforts, 
(and may call you a monkey in the process). Each 
level will also offer a pearl of wit or wisdom from one 
of history's great thinkers to inspire, 
(or goad), you on your quest.

 

"It will exercise your brain and call you a monkey."
