I don't know where you get exactly 600 spins?
If I could win 600 bets in a row my name would be Spike, not Taotie.

Then again, Spike would only have 600 units and I have 15k units.

I haven't run the numbers lately but I think the average number of played spins per game is around 14. That means this exercise is approaching 8500 played spins.
