If the Real Networks icon (a black speech bubble inside a blue square) does not appear in the centre of the box just underneath "Mind Sports Olympiad 3", or if a control panel with triangular "play" and square "stop" icons do not appear once the page has finished loading, then you may not have RealPlayer installed. Click on the "Get free player" button to the right and then follow the instructions that appear to install RealPlayer (we recommend the latest free version currently available - at least 7.0) upon your computer.
