More Hearts Slot
Aristocrat has released several slots over the past few years, and one of them is More Hearts. Now, you might guess this slot features hearts heavily, and you'd be right. In common with some of their other slots, you can play this with 25 or 30 lines, and it's better to go for the second option. This is because the RTP is higher in this instance.
The scattered logo can appear anywhere and pay for three or more, while the diamond wild can replace all but the logo and the single heart symbol. There are a variety of other symbols here, but none of them seem to be connected to a common theme.
More Hearts can unlock free spins, and you get 12 or 15 of these depending on how many lines you played. That's another perk of playing 30 of them, not to mention the chance to collect hearts during the spins and play further reels as well. It's easier to play than to explain, so why not give it a try?
