A slot machine includes a prize display, a coin entry slot, and payout tray and internally mounted game control processor circuits. The game display means comprises a video display screen controlled to display a game image divided into a matrix of elements or player selectable zones. The video screen has an array of touch sensitive areas located on its display surface with one such area associated with each matrix element. The control processor causes an image to be displayed on the display means, such as a sportsman playing his sport and randomly selects one or more of the matrix elements to have a prize associated with it. The player selects one of the matrix elements to have a prize by touching the screen within the area of the respective element to be selected, thereby causing the image in the element to change to reveal the associated prize value. Additional player controls are implemented by displaying images corresponding to controls on the screen such that when the control images are touched, the associated function is caused to be performed. In the event that the player wins the game, by selecting a zone having associated prize value, the machine will pay him a prize equivalent to the prize value in the zone selected by the player multiplied by the number of units bet, if appropriate.
