The basic gameplay consists of a gondola controlled by the player that shoots various treasures (Keys, Hearts, Coins, Rings, Vases, Stars and Lyres) directly upward towards plates that have matching slots on the side of a building in an attempt to match the treasure with its matching slot. Plates come in varied shapes such as bars, circles, half-circles, T-shapes, and X-shapes. They may hold as few as one and as many as eight treasure slots, and they may not be stationary. Some feature hinges that cause them to rotate when hit, while others shift or rotate positions when hit. The player usually has the ability to cycle between two treasures before firing.
