- A bank of three [[gameplay-feature:memory-drop-targets]] — [[gameplay-feature:drop-targets]] that remember which targets the player has knocked down between turns rather than resetting at the end of each ball. The three-bank is the most common memory drop target configuration. IPDB catalogs approximately 3 machines with this specific designation, including *[[title:bad-girls]]* (1988). The carry-over mechanic meant a player could chip away at the three-target sequence across multiple balls, reducing the penalty for draining before completing the bank.
