Abstract

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.

4. A method for use with a gaming machine having a controller, a random number generator, and an electronic display device, the method comprising:
displaying, via the controller, a plurality of separate sub-games simultaneously on the electronic display device, each of the separate sub-games being a spinning reel game of chance comprising a plurality of respective paylines, wherein the number of paylines for any one of the separate sub-games is equal to the number of paylines for any other one of the separate sub-games;
determining outcomes of a first of the plurality of separate sub-games using the random number generator;
determining outcomes of the other of the plurality of separate sub-games based on said outcomes of said first of the plurality of the separate sub-games via the game controller;
