Gaming system and a method of gaming
View Patent ↗A gaming system is disclosed which comprises a symbol selector arranged to select a plurality of symbols for display at a corresponding plurality of display positions, an outcome evaluator arranged to determine whether the selected symbols correspond to a winning symbol combination by evaluating symbols disposed in defined win lines, and a prize allocator arranged to allocate a prize to a player when a winning symbol combination exists in a defined win line. At least one display position is of different size to at least one other display position and the defined win lines are dependent on the respective sizes of and locations of the display positions. A corresponding method is also disclosed.
1. A gaming system comprising:
a symbol selector arranged to select a plurality of symbols for display at a corresponding plurality of display positions;
an outcome evaluator arranged to determine whether the selected symbols correspond to a winning symbol combination by evaluating symbols disposed in defined win lines; and
a prize allocator arranged to allocate a prize to a player when a winning symbol combination exists in a defined win line; and
wherein at least one display position is of different size to at least one other display position and the defined win lines are dependent on the respective sizes of and locations of the display positions; and
wherein the gaming system is arranged to operate in normal game mode wherein display positions are the same size and the defined win lines are independent of the size and locations of the display positions, and special game mode wherein the display positions are of differing sizes and the defined win lines are dependent on the size and locations of the display positions; and
wherein the gaming system comprises a display position modifier arranged during special game mode to replace at least one normal mode display position with a plurality of special game mode display positions, each special game mode display position being of smaller size that a normal mode display position.
2. A gaming system as claimed in claim 1 , wherein the display positions are arranged in display position groups.
3. A gaming system as claimed in claim 2 , wherein each display position group is associated with a reel.
4. A gaming system as claimed in claim 2 , wherein the display positions associated with a display position group are of the same size.
5. A gaming system as claimed in claim 2 , wherein the size of display positions in the display position groups progressively decreases across a display area such that the number of display positions in the display position groups progressively increases across the display area.
6. A gaming system as claimed in claim 5 , wherein the size of the display positions in the display position groups progressively decreases across a display area in a direction from left to right across the display area.
7. A gaming system as claimed in claim 2 , wherein a win line is defined to comprise display positions disposed in adjacent display position groups, each win line comprising one display position from each of said adjacently disposed display position groups.
8. A gaming system as claimed in claim 2 , wherein at least one display position group comprises display positions of differing sizes.
9. A gaming system as claimed in claim 1 , wherein the sizes of the display positions are randomly selected.
10. A gaming system as claimed in claim 1 , wherein the gaming system is arranged to provide fixed display positions, and the symbol selector is arranged to select a plurality of symbols for display in the fixed display positions.
11. A gaming system as claimed in claim 1 , wherein each selectable symbol is associated with a display position size such that selection of a symbol for display effects selection of the display position size.
12. A gaming system as claimed in claim 1 , wherein the gaming system is arranged to commence special game mode when a specific game outcome occurs.
13. A gaming system as claimed in claim 1 , wherein the gaming system is arranged to commence special game mode on the basis of a game event occurring during a game such as display of a particular symbol, in response to player input, based on the amount or type of bet placed, or when a special game is purchased by a player.
14. A gaming system as claimed in claim 1 , wherein the gaming system comprises a gaming machine.
15. A gaming system as claimed in claim 1 , comprising a gaming terminal and a gaming server in networked communication with the gaming terminal.
16. A method of gaming comprising
providing a plurality of display positions, at least one display position being of different size to at least one other display position;
selecting a plurality of symbols for display at respective display positions;
determining whether the selected symbols correspond to a winning symbol combination by evaluating symbols disposed in defined win lines, the defined win lines being dependent on the respective sizes and locations of the display positions;
allocating a prize to a player when a winning symbol combination exists;
operating in normal game mode wherein display positions are the same size and the defined win patterns are independent of the size and locations of the display positions, and special game mode wherein the display positions are of differing sizes and the defined win patterns are dependent on the size and locations of the display positions; and
replacing at least one normal mode display position with a plurality of special game mode display positions during special game mode, each special game mode display position being of smaller size that a normal mode display position.
17. A method as claimed in claim 16 , comprising arranging the display positions in display position groups.
18. A method as claimed in claim 17 , wherein each display position group is associated with a reel.
19. A method as claimed in claim 17 , wherein the display positions associated with a display position group are of the same size.
20. A method as claimed in claim 17 , comprising defining the display positions in the display position groups such that the size progressively decreases across a display area and the number of display positions in the display position groups progressively increases across the display area.
21. A method as claimed in claim 20 , comprising defining the display positions in the display position groups such that the size of the display positions in the display position groups progressively decreases across a display area in a direction from left to right across the display area.
22. A method as claimed in claim 21 , comprising defining a win line to comprise display positions disposed in adjacent display position groups, each win line comprising one display position from each of said adjacently disposed display position groups.
23. A method as claimed in claim 17 wherein at least one display position group comprises display positions of differing sizes.
24. A method as claimed in claim 16 , comprising randomly selecting the sizes of the display positions.
25. A method as claimed in claim 16 , comprising providing fixed display positions, and selecting a plurality of symbols for display in the fixed display positions.
26. A method as claimed in claim 16 , wherein each selectable symbol is associated with a display position size such that selection of a symbol for display effects selection of the display position size.
27. A method as claimed in claim 16 , comprising commencing special game mode when a specific game outcome occurs.
28. A method as claimed in claim 16 , comprising commencing special game mode on the basis of a game event occurring during a game such as display of a particular symbol, in response to player input, based on the amount or type of bet placed, or when a special game is purchased by a player.
