You will notice the iconic Unibet green theme is replicated on the mobile site as well. The mobile version is just a miniaturised version of the main desktop site, with all the betting features remaining intact.
As such, whenever you type in the Unibet URL: in your mobile browser, the site will automatically switch to the mobile version. The optimisation means the site is designed to adjust depending on the device being used to browse automatically. That is made possible by the Unibet website which has been optimising for mobile browsing. In addition to having such diverse betting apps, you can also play at Unibet without having to go through the hustle of installing the downloadable apps.
