The Spy's Adventures in Europe

About

In the game you have to travel to various European countries and their famous locations to search for clues. You may travel only between adjacent countries on the map. Clues will be left behind by friendly agents and indicate where jewels are located. When you will come across an informant, he should be bribed with money or jewels to receive a clue, where Dr. X is. You only have 3 guesses to uncover Dr. X's hideout until the end of the game. If you are successful in your mission, you are given an efficiency rating; the fewer turns you can locate Dr. X in and the more jewels recovered, the better your score will be.
