Abstract: A progressive jackpot system for a gaming network is described wherein the accumulation of the jackpot is based upon any of a number of factors, and the winning of the jackpot is based on any of a number of factors. In one embodiment, the winning of the jackpot may be by any player using a player ID card or a cash-less card to play a gaming machine. The determination of a winner of the jackpot may be based on a random selection of a player's ID code (or cash-less card code) by a network computer.

Abstract: In a system of linked gaming machines, upon a certain triggering event occurring, eligible gaming machines simultaneously receive a signal for initiating a free game bonus round. The players that have been playing the gaming machines will then play a certain number of free games in a competition with other players involved in the same bonus round. A free game pot, common to all the linked machines involved in the free games, pays all awards for the free games. Since the free game pot must fully support the free games prior to a free game round being initiated, and the requirement for the free game pot amount dynamically changes based on the number of eligible machines to be involved in the free game round, the percentage from the wagers for paid games allocated to the free game pot is dynamically adjusted.

Abstract: At least one gaming machine in a network of gaming machines includes displays for a main game and a bonus game. The bonus game is activated when a particular outcome of the main game is achieved. A jackpot that is common to a plurality of the gaming machines in the network may be awarded when certain criteria are achieved in the bonus game. The certain criteria may occur entirely within the bonus game, or may be distributed between the main game and the bonus game. The certain criteria may be, for example, the display of a particular symbol or symbol combination, or a particular outcome of the bonus game.

Abstract: A gaming machine is described wherein a player first plays a primary game, such as the spinning and stopping of mechanical or video reels displaying symbols. A plurality of progressive jackpots is displayed to the player, where the progressive jackpots are incremented at different random rates. Upon a jackpot-winning outcome of the primary game, the number of different progressive jackpots paid to the player depends on the number of credits bet by the player. The jackpots are incremented upon jackpot-incrementing symbols being displayed by the reels. In one embodiment, the jackpot above each column of symbols gets incremented upon a special symbol, such as a credit value, being displayed in that column.

Upon a jackpot-winning outcome of the primary game, the number of different progressive jackpots paid to the player depends on the number of credits bet by the player. In one embodiment, the jackpot above each column of symbols gets incremented upon a special symbol, such as a credit value, being displayed in that column. As the jackpots are won, other jackpots are shifted over the columns to replace the won jackpots. In another embodiment, the determination of which jackpot is won depends on the outcome of the primary game.

Abstract: A group of linked gaming machines generates one or more progressive jackpots, common to all the linked machines, where the amount of each jackpot is increased by a percentage of the wagers made by the players. In accordance with the invention, in order to provide incentive for the player to keep playing the machines and to add additional excitement, non-jackpot awards are paid out to players of the linked gaming machines based on triggering thresholds met by each jackpot. One type of triggering threshold may be a threshold value reached by a jackpot. Upon a jackpot reaching the threshold, one or more players will win an award. After an award win, another threshold level will then be set for the jackpot. Since the frequency of the awards being granted is generally higher than the frequency of the full jackpots being won, the players will anticipate awards being granted and will continue to play the machines.

Abstract: In one embodiment, a gaming machine carries out a main game, such as a spinning reel type game, either using physical reels or simulated reels on a video screen. A special combination of symbols activates a video bonus game. The bonus game comprises a matrix of hidden values in the form of icons that may be selected by the player. The values that may be selected are displayed to the player in an order unrelated to the arrangement of the hidden values in the matrix so the player sees what she can possibly win. The player then makes her selections to win the hidden awards. In one embodiment, the player only makes a predetermined number of selections. In another embodiment, the player makes selections until an end-of-game value is selected. After each selection, the displayed values may change.

Abstract: A system of linked gaming machines is disclosed herein. Upon a certain triggering event occurring, eligible gaming machines simultaneously receive a signal for initiating a free game bonus round. The players that have been playing the gaming machines will then play a certain number of free games in a competition with other players involved in the same bonus round. The player awarded the most credits or points from the play of the free games is awarded a special jackpot. Other jackpot games (e.g., split jackpot) are also envisioned. In another embodiment, a jackpot award or any award to the players may be granted based on the outcomes of the free games. In one embodiment, the base awards to the player(s) for the bonus round are multiplied by a multiplier that may be based on the number of players, based on the players' rankings, based on other outcomes of the bonus round, or a fixed or random multiplier.

Abstract: In one embodiment of the invention, a video gaming machine displays an array of symbols, and an award is granted based on any winning symbol combinations across activated pay lines. As a secondary game, after the initial display of the symbols, the player may designate one species of symbol in the array. Then, one of the symbols in the array is selected at random by the gaming machine. If the symbol designated by the player is the one selected by the machine, the player wins a special award. The secondary game may be activated pursuant to any of a variety of events, or activated after each game. The player may designate the symbol species by means of a touch screen or any other type of controller.

Abstract: In one embodiment of the game, a matrix of symbols is displayed on a display screen. The matrix may be a 3×3 array of symbols or any other configuration. Each symbol has a selectable direction indicator that points to another symbol or out of the matrix. The direction indicators are randomly selected. An award is based on paths created by the direction indicators. The award may be determined by the path from an entrance into the matrix to an exit out of the matrix, or the award may be based on the patterns formed by the paths. The game may be a main game or a bonus game and can be displayed on a display screen or by motor-driven reels.

Abstract: A slant top slot machine is described where a raised translucent or transparent housing for light emitting diodes (LEDs) surrounds the main display area of the machine. In the case of a video machine, the raised housing surrounds the video screen. Light from multicolored LEDs in the housing, when illuminated, is emitted downward from the sides of the raised housing to illuminate the front surface of the slant top surface. In one embodiment, the slant top surface is brushed stainless steel so that the LED light reflects off the stainless steel surface and reradiates the light outward toward the player. In an embodiment where the raised housing raises the video screen and the LEDs above the front surface, the screen is optically separated from the rest of the machine, and the player can more easily concentrate on the game since other features on the front surface appear to be in the background.

Abstract: A backlight for a reel assembly is disclosed comprising a plurality of light emitting diodes (LEDs). An array of red, green, and blue diodes are positioned behind a translucent reel strip to backlight three adjacent symbols on a reel strip. The LEDs are individually controllable to vary the color output of the LED array for a full spectrum of colors including white. Groups of LEDs can be illuminated to optimally illuminate any number of symbols of any size. The LEDs may be controlled to highlight special symbols such as by blinking or changing colors. LEDs are also arranged on both sides of the reel strip in a vertical array so as to outline the edges of the reel strip.

Abstract: In one embodiment, a video slot machine displays an array of symbols, and awards are granted to the player based on certain combinations of symbols across a pay line or in a pattern. While the reels appear to be spinning, or at any time prior to the final symbol display, the player may designate one or more of the positions in the array to be a special symbol. This special symbol may be a wild card, a high value symbol, a scatter symbol, a multiplier, a bonus game trigger symbol, or any other type of special symbol. The virtual reels stop rotating, and all other symbols in the array are then displayed along with the special symbol in the designated position. The player is then granted an award based upon any winning symbol combinations as affected by the special symbol. In another embodiment, the position of the special symbol in the array is selected automatically by the gaming machine.

Abstract: Various bonus games for being played on a gaming machine are described. The base game may consist of the random selection and display of a 5×3 matrix of symbols. In one bonus game (FIGS. 5-7), upon a certain outcome of the base game including special symbols, all symbols in the matrix except for the special symbols are replaced with values, such as different credit amounts. The player selects a particular special symbol using a touch screen, and the identified special symbol randomly moves to select one of the displayed values in the matrix. In another game (FIGS. 11-13), the player applies hidden multipliers to a randomly selected award value in the matrix. In another game (FIGS. 14-19), pointers moving across the matrix of values accumulate values for awarding to the player. The multi-stage interactive bonus games add excitement and more player involvement.

Abstract: A plurality of symbols are randomly selected by a computer in the gaming machine and displayed to the player in the first stage of the process. One or more of the symbols are then selected by the gaming machine in the second stage of the process. An award to the player is based on the one or more selected symbols after the second stage. Such a two-stage process creates additional excitement since the player, after the first stage, hopes for the highest value symbol(s) to be selected in the second stage.

Abstract: Various bonus games for being played on a gaming machine are described. In one embodiment, a base game and bonus game are played on a video screen. The base game may consist of the random selection and display of a 5×3 matrix of symbols, although any size array of symbols may constitute the base game. Upon a certain outcome of the base game, all or some of the symbols in the array are replaced with values, such as different credit amounts. Each value represents a potential bonus award to the player. Various bonus games are described that select one or more displayed values as the outcome of the bonus game.

Abstract: A game variation played on a gaming device displaying reels is disclosed. The game grants awards to the player for certain combinations of symbols. When a player gets one or more special symbols in an initial game, the player gets a free spin of one or more reels while the reels that display the special symbols are held. The player continues to get free spins as long as additional special symbols are displayed after each spin. The player may be granted awards for winning symbols combinations after each spin. In one embodiment, a certain number of special symbols across a payline awards the player a jackpot. In another embodiment, the game is a bonus game where any reels containing special, or trigger, symbols are shifted by one position after each free spin and then held for the next free spin. Only reels that do not display a trigger symbol are spun. The bonus game ends when there are no more trigger symbols displayed. The game may be played on a video gaming machine or a motor-driven reel machine.

Abstract: A control unit in communication with a plurality of gaming machines selects one or more of the active machines to be set to an enhanced play mode. The selection may be random or based on other factors. During the enhanced play mode, free games are provided, or the awards attributed to each symbol combination are increased, or additional symbols combinations are deemed winning combinations, or other game parameters may be changed that are advantageous to the player. The wagers by all the players playing machines connected to the progressive jackpot system are used to set the number of free games or the length of the enhanced play mode. The number of free games increases or the length of time of the enhanced play mode increases along with the jackpot that may be won in the enhanced play mode until the values are reset to starting values upon a jackpot win.

Abstract: A plurality of electronic gaming machines (EGMS) are connected within a network. Each gaming machine is provided with a communication system that allows the player to communicate any information to another player or to a casino representative. The player, while at the gaming machine, selects a communication option via a touch screen monitor and then enters a command or message via a keyboard or buttons. The communications network routes the player's message to a particular receiver address stored in a memory. The player may also communicate verbally using a microphone built into the gaming machine.

Abstract: A control unit in communication with a plurality of gaming machines selects one or more of the active machines to be set to an enhanced play mode. The selection may be random or based on other factors. During the enhanced play mode, the awards attributed to each symbol combination are increased, and the game parameters, other than the award amounts may be changed. In one embodiment, the control unit changes the win frequency of awards granted by the combinations of symbols throughout the entire enhanced play mode. In another embodiment, the symbols forming all combinations of symbols during the enhanced play mode are the same symbols used in the non-enhanced mode for forming symbol combinations.
