When you play Virtual Regatta from your touch-screen computer, it runs on your web browser.
In certain cases, it is possible that your browser allows (or doesn't allow) the game to run using your touch screen. The game, in its current WebGL version (available and playable from the Web) is not optimized to be played on a touch screen.
If you want to play the game in the best conditions using touch screen features, we suggest downloading the App, which was designed for this purpose. The app is available on iOS and Android devices.
