Some lucky... people have won over bet x 4,000 on Dead or Alive
Also over 1000 x bet on some of their other slots.
Go and have a look at the last few months of this thread:

For Wild Rockets the top pay symbol is the Fire Crackers @ x250 for 5 and x100 for 4.
So if you had 1 of those each end and ALL wilds in the middle, you would win 250 x 360 = 90,000 coins plus 100 x 360 = 36,000 coins = 126,000
Minimum coins per spin = 50, so that max win = total bet x 2,520
(I THINK that's right - my head is spinning a bit now!)
Plus of course, the wins you would get for the other 2 symbols appearing on reels 1 & 5. (I don't know what they are)
However... the chances of hitting that must be many millions to one against - so I wouldn't go chasing it if I were you...
