How we rate UK online slots

We’ve got you covered with a library of 20,000+ free casino games – one of the largest selections in the UK. If you’re not ready to make a deposit yet, start playing the most popular UK slots for free below. Megaways slots have six reels and use a random reel modifier that changes the number of symbols on each spin, up to a maximum of seven per reel. Like regular slots, wins come from landing identical symbols on adjacent reels – from as few as three reels to all six for the biggest payouts. Instead, you need to land a group (or “cluster”) of matching symbols. For example, when playing Candy Crush, if you match three or more sweets that touch horizontally or vertically, they disappear, and you score points.
