Abstract

A plurality of gaming machines, such as slot machines or the like, are networked together in communication with a bonus server. The bonus server identifies each machine on the network and transmits a bonus token across the network to a machine control interface within a selected one of the machines. The bonus token is preferably a message packet containing the unique address of the gaming machine selected as well as various parameters which govern aspects of a bonus session initiated at the machine. Receipt of the bonus token signal at the machine causes additional lighting and sound effects beyond that enabled by the normal operation of the game. The bonus token also enables additional bonuses within the game that are awarded to a player of the selected machine. At the end of a bonus period, the bonus token is returned to the bonus server, processed to introduce new parameters, and then transmitted to a second one of the plurality of gaming machines at the proper time. The bonus token is passed in this way, periodically, from machine to machine to enhance the gaming experience of the lucky player of the selected gaming machine.

Claims

1. A method for awarding bonuses over a gaming network having a plurality of gaming machines interconnected by a network, the method comprising the steps of:

allowing play to occur on a plurality of gaming machines;

setting an upper threshold;

accumulating a bonus pool responsive to play on the gaming machines;

selecting a first subset of the plurality of gaming machines when the accumulated bonus pool crosses the upper threshold;

sending a bonus token signal to at least one of the first selected subset of the plurality of gaming machines;

storing the bonus token signal at the at least one of the first selected subset of the plurality of gaming machines over the bonus period; and

initiating a bonus period at only the at least one of the first selected subset of gaming machines responsive to the bonus token signal.

2. The method of claim 1, further including the step of paying out bonus awards from the bonus pool during the bonus period.

3. The method of claim 2, further including the steps of:

decrementing the bonus awards paid during the bonus period from the bonus pool to yield an adjusted bonus pool amount;

setting a lower threshold;

removing the bonus token signal from the first selected subset of gaming machines when the adjusted bonus pool amount crosses the lower threshold; and

ending the bonus period contemporaneous with the step of removing the bonus token signal.

4. The method of claim 1, further including the steps of:

accumulating a temporary bonus pool during the bonus period responsive to play of the gaming machines during the bonus period; and

transferring the temporary bonus pool into the bonus pool at the end of the bonus period.

5. The method of claim 4 wherein the step of accumulating the temporary bonus pool during the bonus period responsive to play of the gaming machines during the bonus period excludes those machines in the first subset of gaming machines.

6. The method of claim 1 wherein the first selected subset of machines is a number greater than one.

7. The method of claim 1, further including the steps of:

removing the bonus token signal from the first selected subset of gaming machines;

ending the bonus period contemporaneous with the step of removing the bonus token signal from the first selected subset of gaming machines;

selecting a second subset of gaming machines;

receiving the bonus token signal at the second subset of gaming machines; and

initiating a bonus period at only at least one of the second selected subset of gaming machines responsive to the bonus token signal.

8. The method of claim 1, further including the step of reserving the bonus token at a bonus server coupled to the network until the first threshold is crossed.

9. A gaming machine network comprising:

a plurality of gaming machines, each of said machines having a machine control interface adapted to operate said gaming machine in either a normal operation mode or a bonus operation mode;

a bonus server linked to the plurality of gaming machines over a network, said bonus server including selection means for identifying at least a selected one of the plurality of gaming machines and signal generation means for generating a bonus token signal;

signal transmission means for sending the bonus token signal to the machine control interface of at least the selected one of the plurality of gaming machines responsive to the selection means, wherein the selected one of the plurality of gaming machines switches from the normal operation mode to the bonus operation mode responsive to the bonus token signal being received at the machine control interface; and

storage means adapted to store the bonus token signal at the gaming machine during an entire period of operation in the bonus operation mode.

10. The gaming machine network of claim 9, further comprising:

a player server linked to the plurality of gaming machines, said player server including a database of player accounts;

player account identification means located at each of the plurality of gaming machines for identifying a player, associated with a respective player account stored within the player server, at the selected one of the plurality of gaming machines;

means for sending a flag signal to the player server responsive to the bonus token; and

means for flagging the respective player account responsive to the flag signal.
