I remember played this game on game machine (called dingdong in Indonesia) in a game center. This is an old game from 1980’s. An arcade game developed by Namco. 19 years later a boy from China named Benny Chow wrote clone of this game as a pet project to learn Java gaming on JDK 1.2. Now this free Blackberry game has become very popular so that Namco asked Benny to remove the download so there is no longer available. You still can play this game online on developer’s website. For the paid version of original game you can go to Blackberry App World website.
