Super Cards
Super cards are small three-by-three side cards on a Bingo Pinball backglass, hung beside the main Bingo Cards and scored on their own. They first appeared on Palm Beach (1952, Bally), which carried two of them, and recur across the one-card machines that followed.[1][2] Their signature award is corner scoring: lighting the four corner numbers of an enabled super card paid 200 or 400 credits — on Palm Beach, the largest single payout in the game.[3][4]
