Description: I have no idea why the author use a name that has nothing to do with rat or sucks. But to my surprise, the game itself was actually pretty fun and addicting. If you have played western chess before, you should know that horse move in L shape. This is not a chess game, both you & computer take turn to move the same horse piece. Each square can only be moved once, the side lose when there is no more movement. The less step you take to beat the computer, the higher score you get. It is a really cool games, try it yourself.
