A control system (1) for an online casino game has a man-machine interface (FIG. 1) operable by a player to regulate the progress of the game, and includes a switch means (8) operable by the player to selectively switch the man-machine interface between two modes in which the player may regulate the progress of the particular game. The two modes are a regular mode in which the interface is of a predetermined complexity, and an expert mode in which the interface is of an increased complexity relative to that of the regular mode. The control system is activatable by the player to automatically regulate the progress of a selectable number of consecutive turns of the game without further intervention from the player. The automatic progress of the consecutive turns of the game is interruptible by the player at anytime before completion thereof. The configuration facility is also configurable to cause the selected number of consecutive turns of the game to progress automatically until all the turns are complete, or to terminate upon winning of a jackpot prize available for the casino game, alternatively upon occurrence of a successful wager, further alternatively upon occurrence of a success wager exceeding a predetermined threshold, still further alternatively upon occurrence of a wager that causes a bankroll of the player to change by more than a predetermined amount.
