Frankly speaking, I have never seen a bigger time-waster than this game. It can take minutes and even hours of your time. Please, believe me. Its simplicity is completely false because it is catching and addictive.You need to throw a ball of paper on the bin. The most interesting thing is that the direction of arrow keeps swinging both right and left. However, there is always a bit of lateral wind and it definitely increases the challenge. Good luck!
