<p>PROBLEM TO BE SOLVED: To improve game amusement by changing the manner of shooting a game medium.SOLUTION: A player shoots a game ball by changing the manner of shooting toward a left game area 2A or a right game area 2B by changing the operation amount (a rotation amount) of a ball shooting operation handle (an operation knob). A probability of the passage (entrance) of a game ball through (to) a second start winning port formed in a normal variable winning ball device 6B is varied between the left game area 2A and the right game area 2B. Respective magnitude relations of the expectation value of a game value to be given when a state is a jackpot game state and the expectation value of a game value to be given after a jackpot game state is terminated are different between a jackpot game state based on the passage (entrance) of a game ball through (to) a first start winning port and a jackpot game state based on the passage (entrance) of a game ball through (to) the second start winning port.</p> |
