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.
