I think the html 5 must have changed because (own experience ofcourse)
I have now played over 400 features on the html 5 one, and not a single wildline, and only two or three times have i gotten the extra spins. Ive also noticed that it now, gives like wilds on four reels, but not matching anything up, very frequently. Like in last 15 freespins i had 9 times four wilds but the freespins paid all under 15x. Also not a single 5 scatter during all these ~50-60k spins. But ALOT of four scatters.
