So this is a bit of a weird one insofar as I don't have any mega win screenshots to show, but I turned a single £60 cash deposit at 3Dice into a withdrawable balance of £416 off the back of a really nice extended run, playing my usual stakes of 20p-30p.
The initial £60 deposit was on a 100% bonus match with a 5xD+B WR (£600), and after I'd turned that over I rolled it into the next deposit of £120 with a 50% bonus, same WR so £900 on that one.
So overall I did £1500 of wagering on 20p-30p spins, and by the time I'd cleared wagering my real cash withdrawable balance was £416. (I got the Deadspin achievement along the way, which is a £25 bonus on a 1xWR, I turned that over playing Gemini and it yielded £21.)
I have nearly nine hours (!) of Bandicam footage, here are some screenies of some of the nicer wins, but as I say, there was nothing singularly amazing, just a very pleasant run of regular features and decent basegame hits. It reminded me of the sort of run it was possible to get on Microgaming slots back in the day on the old Viper client, hours and hours of entertainment for a sensible investment of cash, and the chance to actually be in profit at the end of it all.
