b. determining the winning number by means of the random number generator (RNG) of the game controller (43); c. determining the position of the ball by means of the ball sensor (42); d. determining the position of a label representing the winning number displayed by the at least one graphical roulette-display-system (10) by means of the label controller (44); e. slowing down the mechanical wheel (20) by means of the wheel control unit (60) until it stops and the ball is in a section of the mechanical wheel (20) corresponding to the label representing the winning number displayed by the at least one graphical roulette-display-system (10); f. optionally determining the width of each pocket of the plurality of pockets (21) by means of the game controller (43); g. determining winning and losing bets by means of the game controller (43); h. changing the displayed content displayed by the at least one graphical roulette-display-system (10) by means of the display controller (50); and i. repeating the steps until a predetermined game cycle is reached. ### Claim 12 (depends on 9) method of using a roulette apparatus (1) according to claim 9, said method including the steps of: a. selecting a winning number by a random number generator (RNG) and associating the winning number to a number of a field of numbers displayed by the at least one graphical roulette-display-system (10); b. determining winning and losing bets by means of a game controller (43); c. changing the displayed content displayed by at least one graphical roulette-display-system (10) by displaying the winning and losing bets on a payout table; d. changing the displayed content displayed by the at least one graphical roulette-display-system (10) by changing the field of numbers displayed by the at least one graphical roulette-display-system (10); e. removing or replacing the winning number with a randomly selected or predetermined number of the numbers remaining in the field of numbers displayed by the at least one graphical roulette-display-system (10) or adjust a width of a section in a circumferential direction of the remaining numbers in the field of numbers displayed by the at least one graphical roulette-display-system (10); f. recalculating the odds and/or the payout of each possible bet; and g. changing the displayed content displayed by the at least one graphical roulette-display-system (10) by displaying the odds and/or the payout of each possible bet and each possible bet on the payout table;
