Secret District Boss Fight
Once you have knocked "Aces" Angotti's health down to %50 you can see the boss fight combos
1st Combo
2nd Combo
3rd Combo
And in case you don't want to or can't get to the %50 damage to uncover the combinations, Zynga will gladly take 3 Reward Points to sell you one set!
When you beat Aces for the Bronze you see this
And you will receive one of the "Call His Bluff"
