SLOT GAMES WITH CONNECTED PAYGROUPS ACTING ON SYMBOLS IN A SYMBOL ARRAY
A slot machine game includes connected paygroups in a symbol array that causes prizes to be awarded, as an alternative or supplement to traditional paylines. The connected paygroups are defined in a reel spin result by counting symbols of a designated type that are contiguous horizontally or vertically. Preferably the designated type is matching symbols. The connected paygroups may be enhanced by wild symbols increasing their size or linking two or more groups to form a larger single group of contiguous symbols. To receive an award, groups must meet a minimum designated size. Players can wager on different sets of connected paygroup sizes like traditional games allow wagering for numbers of paylines. Bonus rounds are provided with special features that enhance connected paygroup sizes.
1 . A method of providing a wagering game on a gaming machine having a display, a wager input device, and at least one electronic controller operatively coupled to the wager input device and the display and configured to execute instructions related to the wagering game, the method comprising:
displaying a matrix of symbol location on the display, with every symbol location in the matrix having a symbol therein;
receiving a wager from a player at the wager input device, receiving a game activation at the gaming machine, and in response initiating the wagering game;
after initiating the wagering game, updating matrix of symbols locations to show a new set of symbols with every symbol location in the matrix having a symbol therein;
evaluating the game outcome to determine any prizes to be awarded by:
(a) defining zero or more groups of symbols by locating groups of horizontally or vertically contiguous symbols of designated types;
(b) counting the size of each defined group;
(c) highlighting or otherwise visually emphasizing each group of a designated minimum size;
(d) providing a prize for each group above the minimum size threshold, the prize based directly upon the size of the group.
2 . The method of claim 1 , wherein the step of highlighting or otherwise visually emphasizing the group includes displaying a number visually associated with the group on the display, the number being the size of the group.
3 . The method of claim 1 , wherein the designated types of symbols used to define groups are matching symbols.
4 . The method of claim 1 , in which the prize is further based directly on the type of symbol comprising the group.
5 . The method of claim 4 , further comprising, before receiving the game activation, offering the player a chance to choose among multiple betting arrangements, each awarding prizes for a different set of symbols forming groups.
6 . The method of claim 1 , further comprising, before receiving the game activation, offering the player a chance to choose among multiple betting arrangements, each awarding prizes for a different set of group sizes.
7 . The method of claim 6 , wherein the selection of a betting arrangement including designated small group sizes causes the game to include more symbol possibilities in the set of symbols used to update the matrix.
8 . The method of claim 6 , wherein selected betting arrangements in the multiple betting arrangements result in the game using a larger matrix of symbol locations than other better arrangements in the multiple betting arrangements.
9 . The method of claim 1 , wherein the matrix of symbol locations includes X (horizontal), Y (vertical), and Z (depth) dimensions with at least two symbol locations deep in the Z dimension, and wherein the groups may be formed additionally by being adjacent in the Z dimension.
10 . The method of claim 1 , wherein the set of symbols includes a wild symbol which may appear zero or more times each time the matrix is updated to show a new set of symbols, and wherein the step of defining zero or more groups includes counting the wild symbol as part of every group to which it is horizontally or vertically contiguous, and wherein the step of defining zero or more groups further includes, if two groups of similar symbols are separated by a wild symbol location, forming a larger group including the two groups and the wild symbol location.
11 . The method of claim 10 , wherein a free bonus round is included in the game which is activated by the appearance of a designated trigger condition in the matrix of symbols locations, and wherein the free bonus round includes multiple repetitions of updating the matrix of symbol locations with a new set of symbols, every location in the matrix receiving a symbol, and evaluating the matrix for groups similarly to the evaluation in claim 1 , and further wherein the free bonus round includes a feature activated at least once in the round that recognizes when two groups of similar symbols are separated by a single symbol location which, if filled with a similar symbol would merge the two groups into a larger group, and after the updated matrix is shown to the player, displaying a graphic sequence of altering the single symbol location to be wild and thereby creating the larger group, and awarding a prize based on the size of the larger group.
