Have some fun with this one. I put a max bet at £1024, 100 spins. Played it 17 times in a row, for 16 I had a net gain each time, on the 17th I wiped out all of that and ended up -£1285.
Even with hindsight, stopping at 16 x 100 would only have given me £719. To take £1000 into a casino, leave with £44 profit after a few hours.
