US Patent 9245418 Multiple game gaming machine

A gaming machine comprises a display and a game controller arranged to control images of symbols displayed on the display. The game controller is arranged to play a game wherein at least one random event is caused to be displayed on the display and, if a predefined winning event occurs, a prize is awarded. A plurality of sub-games constitute the game displayed on the display. As an initial display, fewer than a full set of images of each of the sub-games are displayed to show a partial outcome of the game, the fewer than the full set of images being representative of a determination of an expected value for each of the sub-games.
