You have a choice of Cleopatra, Diamond Vault and Majestic Gorilla:
This is how it works
Jackpot bonus round
The jackpot bonus round starts randomly or when 3 or more bonus symbols appear. Open the vault of your choice to obtain coins or bars. As soon as you've collected 3 of the same coins or bars, you win the corresponding jackpot and the bonus game ends.
Whenever you open a vault with bundles of money, the money column goes up. Exceeding the "boost" limits increases the jackpot values. Fill the money column to the very top and win the Fort Knox Jackpot with more than € 200,000*!

The Fort Knox Jackpot requires 4 bundles of money in the vault feature to win the jackpot. As long as they aren't hit, the jackpot continues to grow.
