You’ll then be taken to a mini game, where the aim is to collect as many crown symbols as possible.

Many slots are themed around animals, ranging from those you’ll find on an African safari in Mega Moolah to mischievous bulldogs in The Dog House Megaways. Land scatter symbols to trigger 10 or more Free Games, that often come with special reels or multipliers too. In Buffalo King Megaways, you can score 22 Free Games with Multiplier Wilds.
