There is 1 wild symbol on reel 5 and the symbols around it are
6=K
10=9
0=Wild
9=10
8=J
Wild + Purple Heart is not possible on either reel (that I can see). It is possible on Reel 4.
Max base game hit is pretty hard to work out, as you'd need to find all the combinations of possible wins and see if any of the lower symbols at higher ways outpay the bigger symbols at lower ways. DM me an email address and i'll send you the reelsets. You can give it a go if you want
There are 21 reel sets in total. Each symbol in 'Be My Angel' has it's own reel set and each has another set for the heartstopper. In total the reel sets are
1 for base game
9 for Be My Angel
9 for Be My Angel Heartstopper
2 for Dynamite Lover (not sure if they are both used during both standard and heartstopper, or if there is one for each. I've not checked)
There are also 2 sets of cascade definitions for use in Dynamite Lover
If my statistical maths were better, yes... but it's not haha. Scatter frequency on the reels is 3,2,2,2,3,3. this is quite a lot lower than Danger! High Voltage, which has 3,4,3,3,4,3.
I don't think it makes a difference, as a pair of symbols will be hit less frequently, so it should even out. As above though, my stats isn't great, so I could well be wrong here! Happy to send the reel sets tho, so DM me.
