By today's standards this game would be branded as a "casual game", a simple, yet addictive concept.
The point of the game is to change the tracks and guide the snuckling trains to their destination without same crashing into each other. This may sound simple, but can become quite difficult. Imagine a small (very small) mal with only a few tracks and sidetracks, three or four train stations with many many trains mercilessy making their way, be it clear or not.
The game requires some nerves but first and formost you need to be able to think ahead a few seconds in your head to optimize the running order of the train.
Actually, the game very much resembles the mechanics of DS' Air Traffic Control. The game is fun and addictive and has quite a lot of replay value, especially when you are trying to be the top scores on the leaderboards.
Nice one, which is crying for a remake (Flash ?) actually !
