The Fort Knox Bonus is one of several Slot Toppers that you can choose from to add an extra layer of fun and excitement to your DoubleDown Fort Knox experience. The Fort Knox Bonus may be triggered randomly during any base game spin. Open vaults to reveal prize symbols, and match 3 symbols to claim that jackpot!
|Once you collect three of any type, the bonus round is over and you win that progressive's prize.|
|Some vaults will contain stacks of bills instead.|
Each stack will increase the "cash meter". As the meter fills, it will break through multiple BOOST barriers. Once a barrier is broken, the value of all the jackpots increase. If the meter reaches the top, regardless of what symbols you've already collected, you jump straight to the Fort Knox Jackpot and win the highest reward possible.
