DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
This invention relates to a slot machine, particularly to a slot machine in which a plurality of symbols are displayed on a CRT screen or the like.
BACKGROUND ART
The conventional slot machines are roughly classified in the mechanically operated type in which reels each with a plurality of symbols drawn on the surface of the reels are mechanically rotated to move and stop the symbol rows, and the video type in which the symbols displayed on a CRT screen are electronically controlled to move. The video-type slot machine has various types. One of the types has three reels, and another has four reels. Yet another has reels arranged in a matrix as shown in Japanese Patent Application No. 57-181170.
In the conventional slot machine described above, one slot machine is played by one player alone. While playing, the player of one machine does not communicate with the players of other machines. The players of the slot machines tend to play individual machines isolated from one another.
This invention has been made in view of this shortcoming of the conventional slot machine. The object of this invention is to provide a slot machine which enables the players of individual machines to have feeling of togetherness thereby to enjoy games more.
Another object of this invention is to provide a slot machine which attracts more players by making games more amusing consequently to yield more profit to the installers of the slot machine.
DISCLOSURE OF THE INVENTION
The slot machine according to this invention comprises one main machine, and a plurality of subordinate machines connected to the main machine. Each of the subordinate machines at least comprises a slot, detecting means for sensing the coins inserted in the slot, and paying-out means for paying out coins.
The main machine comprises control means for starting a game in response to an output of the detecting means of a subordinate machine and controlling the proceeding of the game, display means for showing on a screen symbol rows having plural kinds of symbols, which are moved while the game is going on, and payment commanding means for commanding the paying-out means of the subordinate machine to pay out coins in accordance with a preset payment rate when the result of the game is a "win" for a player.
BRIEF DESCRIPTION OF THE INVENTION
FIG. 1 is a perspective view of an embodiment according to this invention; and
FIG. 2 is a block diagram of the embodiment of FIG. 1.
BEST MODES FOR CARRYING OUT THE INVENTION
The slot machine according to the embodiment shown in FIG. 1 comprises one main machine 1, and three subordinate machines 2a-2c. The main machine 1 is connected to the subordinate machines 2a-2c by cables 3, 4a-4c made of optical fibers, wires or the like through a distributor 5. The main machine 1 has a CRT display device 6, for example, on the front side thereof, which displays symbol rows having plural kinds of pictures and patterns for a game of the slot machine. Each subordinate machine 2a-2c has a CRT monitor 7a-7c which displays the same contents as the CRT display device 6 of the main machine 1. Further each subordinate machine 2a-2c comprises a slot 8a-8c in which a player bets coins, a coin outlet 9a-9c, and a speaker 10a-10c which outputs melodic sounds or the like.
The elements shown in FIG. 1 are connected as shown in FIG. 2. The main machine 1 includes a central processing unit (CPU) 11. The CPU is connected to a symbol generator 12, for showing the pictures and patterns in the symbol rows, and a program memory 13 for storing a program for letting the game proceed. The CPU 11 is also connected to a CRT controller 14 for controlling the CRT display device 6 in accordance with a command from the CPU 11.
A subordinate machine 2a includes a display control circuit 15 for controlling the CRT monitor 7a and actuating the speaker 10a in response to a command from the CPU 11, a detector 18a for sensing betted coins inserted in the slot 8a (FIG. 1), and a coin paying-out mechanism 19a for paying out coins to the coin outlet
