Gaming apparatus and playing method thereof

1. A gaming apparatus comprising:

a roulette wheel including a plurality of pockets associated with respective numbers in advance;

a memory for storing a plurality of control data for controlling the gaming apparatus so as to provide different weights on probabilities that a ball is housed in each of said pockets; and

a controller,

said controller controlling rotation of said roulette wheel and launching of said ball by referring to a single control data out of said control data,

determining a number corresponding to one of said pockets with said ball housed therein as a winning number,

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player, and

selecting another control data different from said single control data, out of said plurality of control data, and setting the selected control data as a reference target, when determining that the prize is to be offered.

2. A gaming apparatus comprising:

a roulette wheel including a plurality of pockets associated with respective numbers in advance;

a memory for storing a plurality of control data for controlling the gaming apparatus so as to provide different weights on probabilities that a ball is housed in each of said pockets; and

a controller,

said controller controlling rotation of said roulette wheel and launching of said ball by referring to a single control data out of said control data,

determining a number corresponding to one of said pockets with said ball housed therein as a winning number,

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player, and

selecting another control data different from said single control data, out of said plurality of control data, and setting the selected control data as a reference target, when determining that the prize is to be offered and when said BET placed by the player is an inside BET.

3. A gaming apparatus comprising:

a roulette wheel including a plurality of pockets associated with respective numbers in advance;

a memory for storing a plurality of control data for controlling the gaming apparatus so as to provide a relatively high weight on a probability that a ball is housed in any of the pockets constituting a single group, said single group belonging to a plurality of groups each of which consists of a predetermined number of said plurality of pockets, and the plurality of control data associated with each of said groups; and

a controller,

said controller controlling rotation of said roulette wheel and launching of said ball by referring to a single control data out of said control data,

determining a number corresponding to one of said pockets with said ball housed therein as a winning number,

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player, and

selecting another control data different from said single control data, out of said plurality of control data, and setting the selected control data as a reference target, when determining that the prize is to be offered.

4. A method for controlling a gaming apparatus comprising a programmable controller and a memory, the method comprising:

with the programmable controller:

controlling rotation of a roulette wheel and launching of a ball by referring to a single control data, the single control data selected out of a plurality of control data stored in the memory for controlling the gaming apparatus so as to provide different weights on probabilities that said ball is housed in any of a plurality of pockets included in said roulette wheel and associated with respective numbers in advance;

determining a number corresponding to one of said pockets with said ball housed therein as a winning number;

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player; and

selecting another control data different from said single control data, out of said plurality of control data stored in the memory, and setting the selected control data as a reference target, when determining that the prize is to be offered.

5. A method for controlling a gaming apparatus comprising a programmable controller and a memory, the method comprising:

with the programmable controller:

controlling rotation of a roulette wheel and launching of a ball by referring to a single control data, the single control data selected out of a plurality of control data stored in the memory for controlling the gaming apparatus so as to provide different weights on probabilities that said ball is housed in any of a plurality of pockets included in said roulette wheel and associated with respective numbers in advance;

determining a number corresponding to one of said pockets with said ball housed therein as a winning number;

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player; and

selecting another control data different from said single control data, out of said plurality of control data stored in the memory, and setting the selected control data as a reference target, when determining that the prize is to be offered and when said BET placed by the player is an inside BET.

6. A method for controlling a gaming apparatus comprising a programmable controller and a memory, the method comprising:

with the programmable controller:

controlling rotation of a roulette wheel and launching of a ball by referring to a single control data, the single control data selected out of a plurality of control data stored in the memory for controlling the gaming apparatus so as to provide a relatively high weight on a probability that said ball is housed in any of the pockets constituting a single group, said single group belonging to a plurality of groups each of which consists of a predetermined number of pockets out of a plurality of pockets being included in said roulette wheel and being associated with respective numbers in advance;

determining a number corresponding to one of said pockets with said ball housed therein as a winning number,

determining whether or not to offer a prize based on the determined winning number and a BET placed by a player, and

selecting another control data different from said single control data, out of said plurality of control data stored in the memory, and setting the selected control data as a reference target, when determining that the prize is to be offered.
