I just signed up, but I was confused by the interface.  I think I ended up signing up with a blank password.

The signup page doesn't ask for the password twice, like every other signup page in the world does, so I thought it was a login page.  You shouldn't allow people to use blank passwords either, I think.  I can't find any way of changing my password.  Is there a way?

I made another account, this time specifying a password.  Its receive address is 146aSkxyXWM4U7jPnsXhVHd1RfohnVDhPx.

Thanks!

I sped up the simulation code - there's no need to shuffle all 1000 spots on the wheel when we only ever use the first 6.  It's still pretty slow, being written in Python and all, but I got another result:

average return over 100000 spins is 0.961925

Also, I couldn't find a way to get rid of the big grey 'Send to this address to play for real BTC!' box that popped up showing me my deposit address.  Eventually I found a slightly differently grey coloured X somewhere near the top right corner, but not close enough to the corner to really look like a 'close' button.  That closed the dialog, but it's pretty hard to notice it given its low contrast and unusual positioning.
