From Direct Logic Systems:
Bank It is an additive single player game that challenges the evils of greed and your logical sense to save. Bank It starts with a playing field of 7 objects, ranging from treasure chests, bombs, to bonus items and more. The goal of the game is to bank as much cash as you can before encountering bombs. The decision to keep more cash in your holdings rather than banking it will maximize your winnings, but you risk losing it all. There are many bonus items, such as 5x multipliers, extra lives, bonus cash. But watch out for thieves, bank robberies, and bombs. With each level that is cleared, you are rewarded with an additional multiplier. Keep racking up multipliers and you will gain much, much more cash.
