20.Feb.2010, we passed a curious looking small tennis court with glass walls where some people played with funny colored small rackets with holes instead of strings and tennis balls. We asked one of this guys, Igor, how to play. He explained the rules of this sport called paddle. It is a mixture between squash and tennis, usually played with 4 people, like tennis double. The court is smaller and you may use the side and backwalls for playing.
