The jackpot is 5 bills in a payline....the two gold dollar signs were bulls, i got cash for that....the third bull was off the payline or it would have been more. Needless to say 4 bulls is probably one in millions. 
So if the thrid bull was on a payline and if i would  have gotten the next bull instead of the wild ist would have been bigger. Get 5 bulls on a payline you hit jackpot which is 1.8 million right now.
