A player (Mr. X) must escape his opponents (detectives) in London. The game board represents London and more (only limited availability for detectives) travel possibilities are (taxi, bus, train). From time to time Mr. X has to show up and the detectives respond accordingly to this at the end of a certain number of rounds to be taken.
The gameplay is delightfully simple and you can start directly without much prior knowledge. The simple principle is not synonymous with undemanding, because it is not safe. The group of detectives has very strategic approach to achieve their goal. So it always comes back to the incredibly exciting to fun moments, which gives the game a very entertaining character.
