DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS First Preferred Embodiment With reference to Figs. 1 and 2, an electronic gaming 20 machine 10 is arranged to project indicia 11 relating to games of chance playable on the machine 10 onto a display panel 16. Included in the projected display, is a first identifiable region 14 showing portions of a number of adjoining simulated rotatable reels 26 to 30. Each reel is 25 divided into a given number of symbol containing elements 17, for example 256 elements. In this example the first - 10 identifiable region 14 is arranged to display five columns corresponding to each of the five reels 26 to 30 and three rows 22 to 24 as a matrix 12 of symbol containing elements when the reels are at rest. 5 Typically, the projected display surrounding the first identifiable region 14 is an opaque mask showing indicia relating to the playing of the game as well as decorative and promotional imagery 11. However, as shown in Fig. 2, in the present invention, the display is not limited to the 10 five column and three row matrix of the first identifiable region 14 but may show one or more additional adjoining symbol containing elements 14A of one or more of the five reels. Additional adjoining symbol containing elements may 15 extend from either the upper or lower boundary of first identifiable region 14, or may extend from both, as for example in Fig 2A. In at least some forms of this preferred embodiment, one symbol containing element of each reel may be 20 additionally visible to a player of the game, thus in effect, the matrix 18 then comprises four rows as shown in Fig 2B. However, no restriction is envisaged on the number and disposition of additionally visible symbol containing elements. Figs. 2c to 2E show examples of some of the 25 possible configurations.

- 11 At all times during the playing of a game, the distinction between the first identifiable region 14, which may be regarded as the result matrix, and the additionally visible symbol containing elements, is maintained. This may 5 be achieved in a number of ways. For example the result matrix may be displayed with a clearly defined border 21 such as shown in Figs. 1 to 4. Alternatively, that portion of the display which, when the reels are at rest is defined as the result matrix, may be highlighted, for example by 10 colour, while any additionally visible symbol containing elements are "greyed out". In yet another form of this embodiment, the additionally visible symbol containing elements may appear as if seen through a translucent portion of the panel 16. 15 The adjoining additionally visible symbol containing elements 14A provide to the player an additional appreciation of the patterns of symbols on each of the simulated rotatable reels. Typically reels are simulated to rotate from the top to the bottom of the display area. When 20 adjoining additionally visible symbol containing elements 14A when arranged as extending upwardly from the first identifiable region 14 as shown in Fig. 4, they provide a heightened sense of anticipation to a player who sees a larger number of the symbol containing elements approaching 25 the rest position on a pay line as the reels slow to their rest position.

- 12 Second Preferred Embodiment As shown in Fig. 3A, the displayed symbol containing elements of the five simulated rotatable reels 26 to 30 5 making up the columns of the matrix 18, is again comprised of a first identifiable region 14 and adjoining additionally visible symbol containing elements 14A. In this embodiment, adjoining additionally visible symbol containing elements 14A comprise two additional rows 10 extending from the upper boundary of identifiable first region 14. Third Preferred Embodiment As shown in Fig. 3B in a further particular preferred embodiment of the invention, the additionally visible 15 symbol containing elements 14A comprise all the elements making up two additional rows extending downwardly from first identifiable region 14. Fourth Preferred Embodiment 20 With reference to Fig. 4, in this preferred embodiment also, the display of symbol containing elements 17 comprises a first identifiable region 14 and adjoining additionally visible symbol containing elements 14A, for example as visible through and below the indicia and 25 imagery (not shown for clarity) projected onto the display panel 16.

13 The additionally visible symbol containing elements 14A include at least one additional symbol containing element 17A of at least one of the reels, but during the spinning of the simulated rotatable reels and when the 5 reels are at rest, any additional elements 17A are subjected to an affine scale transformation. That is the width of the element or elements remains that of the width of the simulated rotatable reels and of the elements as displayed in the first identifiable region 14, but the 10 height of each element 17A is reduced to a proportion of the height of the elements 17 as displayed in the first identifiable 'region 14. The example illustrated in Fig. 4 shows additionally visible symbol containing elements 17A making up three additional rows in which the elements have 15 been subjected to an affine scale transformation. Fifth Preferred Embodiment The reduction of the height of the additional elements 17A displayed as additionally visible symbol containing elements, may be limited to that height which allows the 20 undistorted display of the symbol contained within that element, as shown in Fig. 4. However, in at least one preferred form of this embodiment as shown in Fig. 5, the symbols of elements 17A of adjoining additionally visible symbol containing elements 14A, may also be subjected to 25 the same affine scale transformation, retaining their original width but being reduced in height.

- 14 The application of an affine scale transformation to the elements or to both the elements and the symbols contained therein, permits the display in the adjoining additionally visible symbol containing elements 14A of 5 several additional rows, or portions of reels thus further adding to the interest of a player. Sixth Preferred Embodiment It will be understood that the affine scale transformation applied to additionally visible elements 17A 10 of each of a number of additional elements extending from first identifiable region 14, need not be the same affine scale transformation. Thus the proportional reduction of the height of each succeeding element of a reel and the symbol contained in that element extending away frem the 15 first identifiable region, may be subjected to increasing reductions. As shown in Fig. 6, this process will convey the impression to a player that he or she is viewing the actual upper and lower curved shoulders or limits of visibility of a reel. 20 Seventh Preferred Embodiment In this preferred embodiment of the invention, the matrix of symbol containing elements is only displayed as comprising a first identifiable region and adjoining additionally visible symbol containing elements when 25 playing a feature game. The feature game or games may be awarded to a player of a primary game on the machine on the - 15 occurrence of some predefined triggering outcome or event of the main game. Normally, during play of the main game, the display of symbol containing elements is limited to the first 5 identifiable region, the remaining portions of the display panel showing only indicia and imagery associated with the playing of the main game, as well as any information on the potential of a player being awarded one or more feature games. 10 When a feature game is awarded, a portion of the display adjoining the first region becomes translucent, or adjoining additional symbol containing elements are rendered visible to the player in other ways. Eighth Preferred Embodiment 15 The elements comprising the matrix of elements of the above described embodiments may be of conventional rectangular configuration, but in at least one preferred embodiment the delineation of an element, that is, the boundary defining the field containing a symbol, may be any 20 N-sided figure, where N may take the value 1 (thus a circular field) or any value from 3 to 20. In at least one preferred form of N-sided element, as shown in Figs. 7 and 8, the elements 32 are hexagon shape for the value of N=6. Game Implementation 25 Any of the above described embodiments may be implemented on any gaming machine or group of gaming - 16 machine provided with a control module. As shown in Fig. 9, a control module 50 is provided with a microprocessor 52 and working random access memory (RAM) 54. The program code driving any of the described embodiments may be introduced 5 into the control module 50 by connection of a data storage device 56. The device may take any of a number of forms, such as read only memory (ROM), erasable read only memory (EPROM), Compact Flash Card, PCMCIA card and the like. Alternatively, control module 50 may incorporate a hard 10 disc drive to which the code may be written via a suitable input device. Control module 50 acts to implement appropriate elements of the program code according to inputs from a user keyboard 58 and outputs video imagery to at least a 15 main display module 60.
