Wonder Boy has a life meter which consists of a series of red hearts; he starts the game with five red hearts. Whenever he sustains damage those hearts turn black. When all the hearts turn black, Wonder Boy dies, and the game ends. Players score points whenever Wonder Boy defeats enemies and collects certain treasures, and at certain point intervals Wonder Boy receives an additional life heart. Players earn gold throughout the game in order to purchase weapons, magic weapons, and other items in shops and rooms. Gold is obtained from enemies, while some are hidden in odd places such as trees and clouds. The game has an "Hourglass Timer" on the top of the screen; whenever the Hourglass Timer runs out, Wonder Boy loses some life. The Hourglass Timer can be refilled by collecting hourglasses or by visiting hospitals or taverns. In the ZX Spectrum version of the game, a candle represents the timer.
