Bank Vault Bonus is a 5 reel, 20-line video slot with 2-bonus games and a collection bonus jackpot. The game also features wild symbols and scatter symbols.

3 or more symbols on a max coin pay line will activate the Vault bonus. Within the Vault bonus you will try to unscramble 4 numbers to guess the combination of a bank vault lock, and the fewer tries you take, the more credits you will win. Complete this bonus 10 times to reach the incredible Deal or Steal bonus rounds, where you can win up to 50,000 credits! In this bonus, you will pick one safety deposit box to hold, and will choose other boxes to blast open, revealing their contents. At pre-set intervals, the "BANKER" will call you with a credit offer; you can take this offer or continue the bonus game, possible all the way to the end of the bonus to reveal the contents of your box (your win).
As you play you collect all "STACK OF BILLS" symbols from every maxed out pay line. You need to collect 165,000 bills to win the jackpot. Your collection will be saved between playing sessions. As long as you add to your collection every day you will keep it. If you miss a day you will lose 10% of your collection after the first day, another 20% the second day, and a final 20% on the third day. Missed days constitute not adding to your collection for 24 hrs. since last spin. You are guaranteed to win the jackpot if you play long enough, but keep in mind other players are playing for the same pot. It will be a race and you want to get there before they do.
