A mobile slot is a slot game played on a phone or tablet, either in a web browser or through a casino's app. Most new slots are designed mobile-first, with portrait or flexible layouts and touch controls.
They are usually the same games as on desktop, built with HTML5 so one version runs on any device. The maths, RTP and rules are the same, and GB rules apply in full: the 2.5-second minimum spin time, no autoplay or turbo spin, the stake limits, and the display of net position and time played.
Phones make play easier to start and harder to notice, so the account tools that limit time and spending are just as useful on mobile. See our safer gambling page.
