Stacked reel multipliers

Abstract

A slot game may assign a multiplier value to a stacked reel having an outcome including a stack of special symbols or wild symbols. The assigned multiplier value may be selected based on a random game outcome of preceding reels. The slot game may display the stacked reel with the assigned multiplier value or by replacing the stack of special symbols with a single symbol and the assigned multiplier value. The slot game may display a merged multiplier value over adjacent stacked reels, the merged multiplier value being the product of the assigned multiplier values for each of the adjacent stacked reels.

What is claimed is:

 generate third display symbols for a third reel of the set of reels from a third set of symbols having fewer special symbols than the second set of symbols; and   in accordance with the third display symbols comprising a second stack of special symbols, assign a second multiplier value to the second reel.   
     
     
         5 . The non-transitory computer readable medium of  claim 4 , further comprising computer readable code to:
 control the display system to replace the third display symbols with a single symbol.   
     
     
         6 . The non-transitory computer readable medium of  claim 4 , further comprising computer readable code to:
 in accordance with second reel and third reel being adjacent reels among the set of reels, determine a product of the first multiplier value and the second multiplier value as a merged multiplier;   assign the merged multiplier value to the second reel and the third reel; and   control the display system to present the merged multiplier value in accordance with the second reel and the third reel.   
     
     
         7 . The non-transitory computer readable medium of  claim 1 , wherein the computer readable code to assign a first multiplier value to the second reel comprises computer readable code to:
 determine the first multiplier value using a stack counter and a lookup table, such that the assigned multiplier value is based on a number of preceding stacked reels.   
     
     
         8 . A gaming system, comprising:
 a display system comprising one or more displays; and   a control system comprising one or more processors, wherein the control system executes computer readable code which cause the control system to:
 generate first display symbols for a first reel of a set of reels from a first set of symbols having one or more special symbols; 
 generate second display symbols for a second reel of the set of reels from a second set of symbols having plurality of special symbols; and 
 in accordance with the second display symbols comprising a first stack of special symbols: 
 assign a first multiplier value to the second reel, and 
 control the display system to display the first multiplier value in association with the first reel. 
   
     
     
         9 . The gaming system of  claim 8 , wherein the control system further executes computer readable code which cause the control system to:
 generate a random number generator outcome for each reel of the set of reels using a random number generator; and   determine an outcome based on the random number generator outcome for each reel of the set of reels, the first display symbols, the second display symbols, and the first multiplier value.   
     
     
         10 . The gaming system of  claim 8 , wherein the computer readable code to control the display system to display the first multiplier value in association with the first reel comprises computer readable code to:
 control the display system to replace the second display symbols with a single symbol.   
     
     
         11 . The gaming system of  claim 8 , wherein the control system further executes computer readable code which cause the control system to:
 generate third display symbols for a third reel of the set of reels from a third set of symbols having fewer special symbols than the second set of symbols; and   in accordance with the third display symbols comprising a second stack of special symbols, assign a second multiplier value to the second reel.   
     
     
         12 . The gaming system of  claim 11 , wherein the control system further executes computer readable code which cause the control system to:
 control the display system to replace the third display symbols with a single symbol.   
     
     
         13 . The gaming system of  claim 11 , wherein the control system further executes computer readable code which cause the control system to:
 in accordance with second reel and third reel being adjacent reels among the set of reels, determine a product of the first multiplier value and the second multiplier value as a merged multiplier;   assign the merged multiplier value to the second reel and the third reel; and   control the display system to present the merged multiplier value in accordance with the second reel and the third reel.   
     
     
         14 . The gaming system of  claim 11 , wherein the computer readable code to assign a first multiplier value to the second reel comprises computer readable code to:
 determine the first multiplier value using a stack counter and a lookup table, such that the assigned multiplier value is based on a number of preceding stacked reels.   
     
     
         15 . A method implemented by at least one processor in communication with at least one memory, the method comprising:
 generating first display symbols for a first reel of a set of reels from a first set of symbols having one or more special symbols;   generating second display symbols for a second reel of the set of reels from a second set of symbols having plurality of special symbols; and   in accordance with the second display symbols comprising a first stack of special symbols:
 assigning a first multiplier value to the second reel, and 
 controlling a display system to display the first multiplier value in association with the first reel. 
   
     
     
         16 . The method of  claim 15 , further comprising:
 determining an outcome based on the first display symbols, second display symbols, and the first multiplier value.   
     
     
         17 . The method of  claim 15 , wherein controlling the display system to display the first multiplier value in association with the first reel comprises:
 controlling the display system to replace the second display symbols with a single symbol.   
     
     
         18 . The method of  claim 15 , further comprising:
 generating third display symbols for a third reel of the set of reels from a third set of symbols having fewer special symbols than the second set of symbols; and   in accordance with the third display symbols comprising a second stack of special symbols, assigning a second multiplier value to the second reel.   
     
     
         19 . The method of  claim 18 , further comprising:
 controlling the display system to replace the third display symbols with a single symbol.   
     
     
         20 . The method of  claim 18 , further comprising:
 in accordance with second reel and third reel being adjacent reels among the set of reels, determining a product of the first multiplier value and the second multiplier value as a merged multiplier;   assigning the merged multiplier value to the second reel and the third reel; and   controlling the display system to present the merged multiplier value in accordance with the second reel and the third reel.
