Mine was a couple months ago on Twin Spin (yeah, was extremely lucky that day) I was betting £1.25 a spin and my balance went from £2.50 (yes, really) to £302.50. Nearly had a heart attack! Also on Theme Park, tickets of fortune on the Can Tower game I was in a session playing 25p spins and somehow won £220 from a throw in said Can Tower minigame, couldn't believe my eyes, I had to do that thing you see in cartoons where they rub their eyes in disbelief and look again lol. Sorry for lack of screenshots as I don't like to keep them in case I get depressed seeing them after a losing streak. These wins may not be 'big' to some people but for me they were huge.
