In this example, the gaming machine is a stand 5 alone gaming machine 40. In this example, five virtual reels are provided and, as such, representations of the reels are displayed on a graphical display device 44 of a gaming machine 40. The 20 gaming machine 40 in this example includes a secondary display 58 and a touch screen associated with the secondary display 58, In this example, the gaming system is arranged to commence 15 a feature game 258 when a trigger condition exists in the form of appearance of a particular symbol combination such as a defined number of scattered symbols. When a trigger condition occurs 256 after a reel spin 254, directional controls are shown on the secondary display 58 which are 20 used to control movement of an object in the feature game, as shown in Figure 8. In this example, the directional controls 270 appear as arrows distributed adjacent edges of. the secondary display 58. As an alternative, the directional controls may take the form of a cross 272 as 25 shown in Figure 9, respective legs 274 of which are used to control movement of an object. The number of moves available to a player may be predefined, may be randomly selected, or may accumulate based on game events occurring during base game play. 30 The feature game may be of any type wherein the game outcome is dependent on the position of a movable object, for example a strategy type game such as chess, a search game of the type such as a treasure hunt wherein with each 35 move a player moves a character to a location on a map which potentially contains a prize, a sport type game such as soccer wherein with each move a player controls the 2740472,..1 (OHuMeMn P783.A IM - 20 direction of a goalkeeper or the shot direction of a soccer character, or any other game wherein movement of an object by a player influences the outcome of the game. 5 After each movement of the movable object, after all available moves have been made, or after the feature game reaches a state of completion, the gaming system determines an outcome of the feature game 260 and a prize is paid if applicable 264. 10 A further specific example will now be described in relation to flow diagram 300 shown in Figure 10 which illustrates steps 302 to 322 of a method of gaming implemented by a gaming system. In this example, the 15 gaming machine is a networked gaming machine 202 of the type shown in Figure 6. In this example, five virtual reels are provided and, as such, representations of the reels are displayed on a 20 graphical display device 44 of a gaming machine 202. The gaming machine 202 in this example includes a PMM display 64 and a touch screen associated with the PMM display 64. In this example, the gaming system is arranged to commence 25 a feature game 314 when a trigger condition exists in the form of a player input indicative that the player wishes to commence the feature game. when the trigger condition occurs 310, directional controls are shown on the PMM display 64 which are used to control movement of an object 3D in the feature game. In this embodiment, the number of moves available to a player accumulate based on game outcomes occurring during base game play, and the feature game may be caused to commence by a player at any time. 35 The feature game in this example is a chess game 330 as shown in Figure 11. The chess game 330 may be displayed on the PMM 64 together with the directional controls as $74804721 (GHMaters) P7B883.AU.1 - 21 shown in Figure 11, or the chess game may be displayed on the primary or secondary display with the directional controls shown on the PTM display 64. 5 With each available move, a player may make any valid move of the player's chess pieces according to the rules of chess, after which the gaming machine 202 will automatically move one of the machine's chess pieces. After completion of the chess game, the gaming system 10 determines whether the player has won the chess game or whether other feature game conditions correspond to a winning outcome and a prize is paid if appropriate. In this example, the gaming machine 202 is in networked 15 communication with the loyalty program server 212 which is arranged to store details of the current feature game in a feature game record 216 such as the current state of the feature game including in this example the current position of the chess pieces.
