PROBLEM TO BE SOLVED: To provide a 1st class PACHINKO machine with which the number of game balls to be dispensed in 'high probability state' can be controlled with high precision and fluctuation in the number of game balls can be suppressed. SOLUTION: Concerning a PACHINKO machine 1, when game ball pass through left and right gates, an ordinary picture pattern displayed on an ordinary picture pattern display part 9 starts varying and when the varied ordinary picture pattern shows 'small success picture pattern', an ordinary motor-driven role object 4 is opened. Besides, when any game ball gets a prize at the ordinary motor-driven role object 4, a special picture pattern displayed on a special picture pattern display part 3 starts varying. When the varied special picture pattern shows 'specified picture pattern', 'great success state' advantageous for a player occurs and after that 'great success state' in finished, 'high probability state' occurs for increasing the display probability of 'small success picture pattern' on the ordinary picture pattern display part 9. After the lapse of prescribed time just from opening or when any other game ball gets a prize, the ordinary motor-driven role object 4 opened by displaying the 'small success picture pattern' is closed. |
