How the Game Plays

Bank Boom is a high-stakes heist slot from Lightning Box Games that takes place within the high-security vault of a luxury bank. The game utilizes a 5x4 grid and 1,024 ways to win, where payouts are awarded for matching symbols on adjacent reels starting from the leftmost side. The reels are populated by a crew of characters including a banker, a socialite, and a master thief, alongside tools of the trade like pickaxes and shovels. The Prisoner serves as the game's wild, appearing on the middle four reels to help complete winning combinations.

Hold & Win Respins Explained

Triggered by landing three or more Dynamite Scatters, the bonus feature moves the action beneath the bank's floorboards. Instead of traditional free spins, this round uses a "Hold & Win" mechanic with three respins that reset every time a new scatter symbol appears. During the round, dynamite clears away dirt to move safe symbols toward a collection zone at the bottom of the grid.

Safe Collection & Jackpots Explained

As safes reach the collection zone, they are unlocked to reveal cash prizes or one of four fixed jackpots. The rewards include the Mini, Minor, Major, and Grand Jackpots, the latter of which provides a prize of 1,000x the stake. The feature concludes when the respin counter reaches zero or when the maximum number of safes has been successfully collected.
