Abstract: PROBLEM TO BE SOLVED: To prevent a game from being monotonous and to realize a game machine which does not bore a player by devising a method for determining whether a jackpot or not. SOLUTION: When it comes to time t5 from starting of varying special symbols, the middle symbol row varying at last provisionally stops, and then, when it comes to time t6, the left symbol row and the right symbol row vary again respectively, and then, when it comes to time t7, the left symbol row and the right symbol row provisionally stop respectively, and then, when it comes to time t8, the left symbol row varies again, and then, when it comes to time t9, the left symbol row stops. That is, because a symbol row to sop at last can be changed from the middle symbol row to the left symbol row, a game can be further prevented from being monotonous than a conventional game in which a symbol row to stop at last is fixed.

When the frictional disk 1 is rotated, oil flows to the outer diameter side by centrifugal force to achieve an effect to cool frictional heat at linear portions shown by an arrow A, and oil is accumulated in oil grooves b due to the difference between the total channel areas of the oil grooves (a) and the oil grooves c to generate pressure, and the riding force over the thickness of the frictional material 10 is generated at nearly T-shaped butt portions shown by an arrow B.  At a clutch release, separating force between the frictional plate 1 and a separator plate, for example, is applied in cooperation with the pressure of the oil grooves b and riding force over the T-shaped butt portions, thereby resulting in so-called good disengagement of a clutch.
