Abstract: A gaming machine presents a game in which an upgradeable object accrues value. The gaming machine includes a player input interface, a credit input mechanism and a game controller configured to perform operations. The game controller presents a primary game, in which a plurality of reels are simulated, spins the plurality of simulated reels each time a player makes a wager, determines, a number of scatter symbols stopped and displayed from the reels, triggers, a bonus game in which an appearance of the upgradeable game object is upgradeable and in which a credit value associated with the upgradeable game object is upgradeable, upgrades the appearance of the object, increases the credit value associated with the object, and adds the credit value associated with the object to the credit balance of the player.
