Description

Field of the Invention

The present invention relates to a gaming system, a method of gaming, a game controller and computer program code.

Background to the Invention

It is known to provide a gaming system which comprises a game controller arranged to randomly display several symbols from a predetermined set of symbols and to determine a game outcome such as a game win based on the displayed symbols. Such gaming systems may commonly be implemented as a stepper machine provided with reels with each reel carrying several symbols of the set, or a video machine wherein selected symbols are displayed on virtual reels on a video display.

While such gaming systems provide users with enjoyment, a need exists for alternative gaming systems in order to maintain or increase player enjoyment.

Summary of the Invention

In accordance with a first aspect of the present

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 2 invention, there is provided a method of gaming comprising:

providing one or more reels in a spinning reel game, the reels being displayed as three dimensional and displayed as provided with game symbols along and around the reels;

displaying spinning of the reels and thereby sequentially displaying at least some of the game symbols displayed as provided along the reels;

displaying rotating of the reels and thereby sequentially displaying at least some of the game symbols displayed as provided around the reels;

stopping the spinning and the rotating of each of the reels at a respective stop position; and determining a game outcome based on at least some of the game symbols displayed when each of the reels is in its respective stop position.

In one particular embodiment, the method includes displaying the reels as toruses.

Thus, one or more spinning reels are provided that both spin and rotate. It should be understood that, herein, the term spin refers to the motion of a reel that is typically observed in spinning reel games of the background art, whereas rotate refers to the motion of a toroidal reel whereby an outer surface of a reel progressively becomes an inner face and vice versa (as is further explained below).

In one particular embodiment, the method includes displaying the reels as provided with game symbols inside the reels .

In one embodiment, the method includes displaying the reels as spinning from top to bottom. This motion is comparable to the motion of spinning reels in spinning

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 3 reels games of the background art. The reels can be displayed to spin at different speeds, displayed to rotate at different speeds, or both.

In a certain embodiment, the method includes displaying the reels as rotating from left to right or from right to left. This motion would therefore commonly be - or appear to a player to be - perpendicular to the top to bottom spinning of a reel. Combined, it should be noted, spinning from top to bottom and rotating from left to right or from right to left may create the illusion that game symbols are moving somewhat diagonally.

In one embodiment, the method includes providing the spinning reels with circular cross sections, that is, that the spinning reels are shaped like doughnuts.

In one embodiment, the method includes providing the spinning reels with polygonal cross sections (such as square, triangular, pentagonal and hexagonal cross sections).

In one embodiment, the method includes stopping the reels from rotating before stopping the reels from spinning.

In a particular embodiment, the method includes stopping the reels from rotating or spinning temporarily during a game. During such a temporary stop, the reels may in effect change their direction of rotation or spin.

The method may include displaying nudging of the reels, whether from top to bottom (or vice versa), left to right (or vice versa) or any combination of these directions.

Thus, nudging - and other reel movements - can be implemented according to this aspect of the invention.

The nudging can be vertical or horizontal or in a

10245776_1 (GHMatters) P72442.AJ.5

- 4 2018203412 15 May 2018 combination of directions, owing to the ability of the reels to rotate as well as spin. The eligibility of a player to nudge one or more reels may follow known criteria, such as by purchasing a nudge, only when certain symbol combinations are displayed, only in features, only for special players, etc. Nudges may be made available on a restricted basis (such as in one direction only) or a more extensive basis (up to four directions), accordingly. The instigation of the nudge may be either automatic or by player instruction. As nudge may be available in both horizontal (i.e. rotational) or vertical (i.e. spin) directions, additional button functions may be provided so that a player can place the precise nudge instruction desired, including - where desired or permitted 15 simultaneously horizontally and vertically.

The method may include displaying one or more of the game symbols as held symbols, or one or more of the reels as held reels. The method may include providing a hold and spin feature, whereby a player can arrest one or more reels (from spinning, rotating or both) and allow the remaining reels to move (spinning, rotating or both).

In certain embodiments, the method may include displaying the reels as transparent or partially transparent.

The method may include displaying one or more additional game symbols, such as within one or more of the reels.

The method may include displaying the additional game symbols on respective objects (such as balls), as separate objects, or on one or more additional reels (which may be displayed, for example, behind or within the reels, or in some cases - nested within each other). The additional game symbols may be displayed as moving within, outside, or through the reels, or combinations of these, including from being associated with (such as inside) one of the reels to being associated with (such as inside) another of

10245776_1 (GHMatters) P72442.AJ.5

- 5 2018203412 15 May 2018 the reels .

The additional reels may be strips (i.e. two dimensional) or three dimensional, and both two dimensional reels and three dimensional additional reels may be displayed successively or simultaneously. Both two and three dimensional additional reels may be displayed as rotating as well as spinning. The reels and the additional reels may move simultaneously or separately, and some additional reels may move separately from other additional reels. Additional reel creation, activation or control may be according to predefined rules, in response to player intervention, or both .

In some embodiments, some or all of the reels are displayed as compound reels, each comprising an inner twoor three-dimensional reel and an outer at least partially transparent three-dimensional reel, all provided with game symbols. The inner reel (or reels) may spin and the outer reel (or reels) rotate, or vice versa. For example, in one embodiment the method includes displaying each of the reels as a compound reel comprising an inner threedimensional reel displayed as provided with game symbols and an outer partially transparent three-dimensional reel displayed as provided with game symbols, at least some of the game symbols provided on the inner reel visible through the outer reel, the method including displaying spinning of the outer reel and rotating of the inner reel (or vice versa).

The method may include displaying one or more of the reels as altering in shape. In such embodiments, the method may include displaying the number or distribution of the game symbols as altering. For example, one or more of the reels may be displayed as being transformed such that a 5x3 matrix of game symbols (i.e. 5 symbols along a reel and 3 symbols around a reel are contained within a player

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 6 viewable window) are transformed into a 5x4 matrix of game symbols .

In accordance with a second aspect of the present 5 invention, there is provided a game controller for a gaming system, the game controller arranged to:

provide one or more reels in a spinning reel game, the reels being displayed as three dimensional and displayed as provided with game symbols along and around the reels;

As discussed above, embodiments are provided according to the present invention that are implemented in relation to a spinning reel type game, the gaming systems for implementing these games having a video display.

According to these embodiments, the reels of the spinning reel type games are each of three-dimensional, torus form.

An example of such a video display with exemplary reels according to one embodiment of the invention is shown schematically at 130 in figure 6. Video display 130 has a viewable region 132 in which are displayed portions of five reels 134a, 134b, 134c, 134d, 134e. Reels 134a,

134b, 134c, 134d, 134e are displayed as toroidal with circular cross-sections, and hence doughnut-shaped; this can be done by shading or otherwise rendering the reels appropriately. For example, viewable region 132 may be enlarged so that upper and lower peripheries 136a, 136b of reels 134a, 134b, 134c, 134d, 134e are shown as curved.

In addition, game symbols visible along reels 134a, 134b, 134c, 134d, 134e are progressively foreshortened towards

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 17 upper and lower peripheries 136a, 136b, consistent with the toroidal form of the reels. Reels 134a, 134b, 134c, 134d, 134e are displayed to appear to spin from top to bottom during game play.

Figure 7 is another schematic view of the player interface 12 and a game controller 14 of figure 1, with more detail shown in the game controller 14. Specifically, processor 12 of game controller 14 includes a display controller

140, a spinning module 142 and a rotation module 144. The display controller 140 controls the view that is displayed on displays 34, 82; spinning module 142 controls the manner in which reels 134a, 134b, 134c, 134d, 134e are displayed when displayed to spin and rotation module 144 controls the manner in which reels 134a, 134b, 134c, 134d, 134e are displayed when displayed to rotate. Processor 12 also includes an outcome determiner 146 (typically receiving input from the random number generator), for determining game outcomes. Display controller 140, spinning module 142, rotation module 144 and outcome determiner 146 cooperate to display and determine the outcome of a game.

In addition, memory 24 includes reel data 148 comprising vertical sequence data 150 and horizontal sequence data 152. Vertical sequence data 150 is indicative of the sequence in which game symbols are to be displayed along each of reels 134a, 134b, 134c, 134d, 134e and horizontal sequence data 152 is indicative of the sequence in which game symbols are to be displayed around each of reels

134a, 134b, 134c, 134d, 134e. This can be encoded in any convenient way; for example, vertical sequence data 150 can indicate, for each of reels 134a, 134b, 134c, 134d, 134e, four sequences of game symbols with horizontal sequence data 152 indicating where each of the vertical sequences should commence . Alternatively, vertical sequence data 150 can indicate, for each of reels 134a,

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 18 134b, 134c, 134d, 134e, one sequence of game symbols to be displayed along the respective reel, with horizontal sequence data 152 indicating the sequence of game symbols to be displayed around each reel from each of the game symbols indicated in by the vertical sequence data 150.

Although in this embodiment reels 134a, 134b, 134c, 134d, 134e are displayed as toroidal with circular cross sections, in other embodiments, the reels may be displayed with other shapes such as toroidal with square crosssections . Such an embodiment is shown schematically in figure 8, which depicts a video display 160 in which are displayed reels 134a', 134b', 134c', 134d', 134e'. These reels spin in the same manner as do reels 134a, 134b,

134c, 134d, 134e of figure 6, and carry essentially the same game symbols .

Referring to figure 7, game play instructions stored in memory 24 control reels 134a, 134b, 134c, 134d, 134e to be displayed to spin such that game symbols arranged along reels 134a, 134b, 134c, 134d, 134e are displayed as moving downwards in the viewable region 132.

Reels 134a, 134b, 134c, 134d, 134e also have game symbols located around their three dimensional surfaces, such that four game symbols correspond to each symbol position along any reel; hence, in the stopped configuration shown in figure 6, three additional game symbols are concealed or otherwise not displayed for each displayed game symbol.

Thus, reels 134a, 134b, 134c, 134d, 134e may be described as being provided with plural sets of four game symbols, the sets displayed along the reels with each set arranged around a reel. The overall effect is that game symbols are displayed both along and around the reels.

The game play instructions stored in memory 24 also control reels 134a, 134b, 134c, 134d, 134e to spin or

- 19 rotate (as seen by the player) from left to right in the view of figure 6. This progressively brings into view other game symbols, and a new selection of game symbols is completely displayed once the reels have rotated through

90°. This process is illustrated by reference to figures

9A and 9B. Referring to figure 9A, after reels 134a,

134b, 134c, 134d, 134e have rotated through 45°, the original selection and a new selection of game symbols are both partially visible and, referring to figure 9B, after reels 134a, 134b, 134c, 134d, 134e have rotated through a total of 90°, the original selection of symbols has been entirely replaced in the viewable region 132 by the new selection of game symbols. A sequence of such rotations results in what was originally an outer face of reels

134a, 134b, 134c, 134d, 134e becoming an inner face, and vice versa.

It should be noted that, although in this embodiment in the configuration of figure 6 the four game symbols at each vertical position (one displayed and three at the same position along a reel but not displayed) are at the same vertical position, in other embodiments this may not be so. For example, game symbols may be arranged around a reel in a generally helical manner.

The disposition of game symbols on reels 134a, 134b, 134c, 134d, 134e as displayed before this latter rotation is shown schematically in figures 10A to 10E (corresponding to the reels notionally being viewed in direction 138 in figure 6). The player normally views reels 134a, 134b, 134c, 134d, 134e in direction 162, so the game symbols shown in figures 10A to 10E are not in fact displayed in the configuration of these figures (which, indeed, corresponds to that of figure 6). The symbols shown in figures 10A to 10E to the right of centre-lines 164 of each reel are those that are displayed once reels 134a, 134b, 134c, 134d, 134e have rotated 90° (viz. the

10245776_1 (GHMatters) P72442.AJ.5

2018203412 15 May 2018

- 20 configuration shown in figure 9B).

In play, reels 134a, 134b, 134c, 134d, 134e may be controlled to spin from top to bottom and to rotate from right to left simultaneously or sequentially; indeed, this motion may be in the opposite directions to those illustrated, or multiple directions in the course of one game. Reels 134a, 134b, 134c, 134d, 134e may spin in different directions, such as with all reels 134a, 134b,

134c, 134d, 134e spinning from top to bottom (as shown in figure 6), some rotating from left to right (as shown in figures 8A and 8B) and the others rotating from right to left. In one particular embodiment, reels 134a, 134b, 134c, 134d, 134e initially spin from top to bottom and rotate from left to right simultaneously, but cease rotating - with a column of game symbols aligned centrally in each reel as viewed by the player (such as is shown in figures 6, 8 and 9B) - before ceasing to spin from top to bottom. The spinning from top to bottom is then controlled to stop such that a pay line is visible to the player. The ceasing of left to right rotation before top to bottom spinning heightens the player's experience, as it can lead to the appearance of an apparent near miss.

The time delay between the ceasing of left to right rotation and the ceasing of top to bottom spinning is controlled by the game play instructions in a memory 24, but can be set to any desired period; in one embodiment this period is 3 seconds, but shorter or longer periods may be employed. This period is typically fixed for any particular gaming system according to the present invention, but in some embodiments may be altered during a set of games by the game play instructions, such as on the basis of previous game outcomes, or randomly.

Although it may be preferred to display the reels as toroidal (as shown in figures 6 and 8 to 9E), in some embodiments the reels are displayed as essentially

10245776_1 (GHMatters) P72442.AU.5

2018203412 15 May 2018

- 21 straight three-dimensional figures, such as cylinders, tubes or rods (or, for example, square cross section). Figure 11 is a schematic view of visual display 170 according to such an embodiment, with reels 172a, 172b,

172c, 172d, 172e each in the form of a tube. The reels are rendered to appear to comprise straight tubes, so there is no foreshortening of game symbols towards their upper and lower peripheries 174a, 174b. Figures 12A to 12C depict viewable region 132 with possible reels according to such an embodiment, in successive positions. In figures 12A and 12B the reels are shown rotationally displaced relative to each other, illustrating the effect of the rotation of game symbols. Figure 12C depicts the effect on game symbols once spinning is added, and hence combined with rotational movement: the game symbols are no longer in ranks either vertically or horizontal, producing a novel game experience.

In certain embodiments, the reels are displayed as having more complex shapes; they may be displayed as bent or curved, or forming S shape, a U shape or otherwise. In addition, in some embodiments, some or all of the reels are displayed as joined to one another. For example, an S shaped reel may be displayed as joined to another S shaped reel or to, for example, a U shaped reel.

As is described above, in the embodiment of figure 6, the reels stop with a column of game symbols aligned centrally in each reel as viewed by the player. In some embodiments, however, one or more reels may have stop positions in which more than one game symbol displayed as arranged around the reel is displayed to the player, and the game outcome may - in such embodiments - take game symbols in this manner into account. Hence, a game outcome may be determined from more than two rotating symbols on at least one reel. For example, if a reel is of square or regular hexagonal cross section, the reel's

10245776_1 (GHMatters) P72442.AU.5

2018203412 15 May 2018

- 22 stop position may display two or three game symbols, and these - in some embodiments - may influence the game outcome.

Figure 13 is a schematic view of visual display 180 according to such an embodiment, with reels 182a, 182b, 182c, 182d, 182e each in the form of a torus of square cross section. Reels 182a, 182b, 182c, 182d, 182e have plural possible stop positions, including those shown in figure 8. However, figure 13 depicts alternative stop positions in which two game symbols are displayed at each position along each reel. More complex game outcome determinations can then be made; for example, a bonus may be awarded if two identical symbols are visible (in viewable region 132) at the same location along one or more reels. This is so in the illustrated example: two pairs of hearts 184, 186 are displayed, on fourth reel 182d and on fifth reel 182e respectively. A single game may include a mixture of stop positions, with one or more reels stopping with a single column of displayed symbols (cf. figure 9B) and one or more other reels stopping with plural columns of displayed symbols (cf. figure 12).

Numerous variations are possible according to the present

5 invention. For example, in the above embodiments, the reels are displayed as essentially opaque, with game symbols displayed on the outside of the reels. In some other embodiments, the reels are displayed as transparent or partially transparent, so that additional effects and features can be provided.

For example, a reel may be displayed as transparent and filled or partially filled with a fluid that is displayed to behave, for example, like water. The extent of this filling can be varied with time or according to other parameters, with the degree of filling used to determine additional prizes, bonuses or games features. The filling

10245776_1 (GHMatters) P72442.AU.5

2018203412 15 May 2018

- 23 can also be provided by other than fluids; for example, the reels may be progressively displayed as filled partially or completely - with balls or other objects.

An example of such an embodiment is shown in figure 14, which depicts viewable region 132 with possible reels and various water levels. From left to right, first to fifth reels 188a to 188e are provided with game symbols along their vertical length (as are depicted) and around their circumference (concealed in this view), and are displayed as essentially transparent. Each is displayed as filled to varying levels with water. First reel 188a is partially filled, such that only one visible game symbol is backed by the water. Third reel 188c is full, and second, fourth and fifth reels 188b, 188d and 188e are displayed as half full.

These final levels of the water can be used, in this embodiment, to determine game or prize outcomes. For example, in one game three like symbols (e.g. buildings) may in their stop positions be located on the centre line of the first three reels (e.g. reels 188a, 188b, 188c). Water is then displayed as flowing down into all five reels and settling to varying levels, such as to the bottom position of the first reel 188a, the top position of the second and fourth reels 188b, 188d and to the centre position of the third and fifth reels 188c, 188e. The prize is evaluated with reference to these water levels: the water is behind two of the kings (i.e. in the second and fourth reels), so the prize is doubled and doubled again. Eligibility for the water feature can be based on any suitable criterion or criteria, such as would be appreciated by those in the art, such as by being purchased by a special bet, made available in all games, made available only during features, or made available to players with a player card status.

10245776_1 (GHMatters) P72442.AU.5

2018203412 15 May 2018

- 24 In another example in which the reels are transparent or partially so, game symbols are displayed as falling down (or floating up) inside a reel or reels, and coming to rest at different locations to thereby contribute to prize evaluation. The game symbols can be in a variety of forms. For example, the symbols may be in the form of indicia on objects (such as balls or stars), or comprise those objects (such as a letter-shaped object or a starshaped object). In either case, a star - for example 10 may be displayed as falling inside a reel and stopping, such as behind one or more game symbols on the reel.

Prizes are then evaluated and may pay additional value if such a symbol is behind or otherwise aligned in a predefined manner with one of the game symbols on the reel.

In such embodiments, the falling symbols may be stopped either randomly or in response to some player intervention or skill. Similarly, in the embodiments in which a fluid is displayed as filling one or more reels, players may be provided with the ability to intervene to enhance, inhibit or stop the filling.

In certain embodiments, the falling symbols or filling fluid may constitute an essentially separate game, though played simultaneously with the spinning and rotating reel game. For example, falling game symbols in the reels may comprise keno balls, their stop positions determining the outcome of a keno game.

Also, the falling (or floating) symbols or filling fluid, in some embodiments, trigger features, such as jackpots.

It will also be appreciated that other features known in electronic gaming machines and the games provided thereby can be advantageously and synergistically combined with the features described above.

The basic method 190 of the above embodiments of the invention is summarised in figure 15. At step 192, the game play instructions commence a game, typically including receiving input from the random number generator for use in determining the conduct of the game. At step 194, the reels are spinning from top to bottom and rotating from left to right simultaneously. This may create the illusion that the game symbols are moving diagonally.

At step 196, the reels spin and rotate for a predefined period. At step 198, the game play instructions progressively slow the motion of the reels in both directions. At step 200, the rotating of the reels from left to right is stopped. Subsequently, at step 202, the spin of the reels from top to bottom is stopped.

At step 204, the game outcome is determined based on the stop positions of the symbols, as finally displayed to the player.

Modifications and variations as would be apparent to a skilled addressee are deemed to be within the scope of the present invention. For example, the reels may have different cross sections, such that - for example - reels of circular cross section are mixed with reels of square, triangular, pentagonal or other cross section. In addition, the number of symbols spaced around the periphery of the reels may differ from the four described above. For example, if the reels have hexagonal cross sections, six symbols may be spaced around each reel in each position. In such cases, non-displayed symbols may be partially visible even when the reels have stopped, which can also heighten the player experience.

Furthermore, a game may be provided in which one or more three dimensional, torus shaped reels are accompanied by

10245776_1 (GHMatters) P72442.AU.5

2018203412 15 May 2018

- 26 other reels, such as conventional, ribbon shaped reels.

In the claims that follow and in the preceding description of the invention, except where the context requires otherwise owing to express language or necessary implication, the word comprise or variations such as comprises or comprising is used in an inclusive sense, that is, to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.

Further, any reference herein to prior art is not intended to imply that such prior art forms or formed a part of the common general knowledge in any country.
