I had to watch mine back now I've sobered up (I really need to stop drinking) but..... it turns out being pissed as a fart helped.....
I was a little confused why on earth I was being dumb enough to do £15 spins..... it was a flipping miss click, I was aiming for £3 (which is a stupidly large bet for me) and completely missed and don't seem to have realised I hit £15...... thank god it worked out well in the end.... (and after only 3 spins at that level).
Time to take my winnings and retire from gambling I think.
