Slot machine and playing method thereof
View Patent ↗In the base game, when a winning combination is realized by a plurality of symbols rearranged on a display, a control for holding symbols related to this winning combination and carrying them over to a next base game is carried out, and symbols related to a newly realized winning combination are held instead of symbols already held only in case where a payout amount for the winning combination is greater than a payout amount for a winning combination already held.
1. A slot machine, comprising:
a display having a plurality of display regions, for arranging and rearranging symbols in the display regions in each unit game; and
a controller:
(a) holding symbols related to a prize in a case where the prize associated with a credit payout is generated by symbols rearranged in a unit game, and
(b) holding symbols related to a prize realized in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount by a prize realized in the previous unit game is different from a payout amount by a prize realized in the current unit game, when a new prize associated with a credit payout that includes symbols rearranged by the current unit game is generated in a subsequent unit game.
2. The slot machine of claim 1 , wherein the controller holds symbols constituting a winning combination which is rearranged in the current unit game instead of symbols held in the previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination which is a prize realized in the previous unit game.
3. The slot machine of claim 1 , wherein the controller sets an upper limit for a number of unit games by which identical symbols are to be held.
4. A slot machine, comprising:
a display having a plurality of display regions, for arranging and rearranging symbols in the display regions in each unit game; and
a controller:
(a) holding symbols constituting a winning combination when a winning combination is rearranged in the display regions in a unit game, and
(b) holding symbols constituting a winning combination which is rearranged in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination by symbols held in the previous unit game, when a winning combination is rearranged by the current unit game in a subsequent unit game.
5. The slot machine of claim 4 , wherein the controller sets an upper limit for a number of unit games by which identical symbols are to be held.
6. A slot machine, comprising:
a display having a plurality of display regions, for arranging and rearranging symbols in the display regions in each unit game; and
a controller:
(a) holding symbols constituting a winning combination when a winning combination is rearranged in the display regions in a unit game,
(b) holding symbols constituting a winning combination which is rearranged in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination by symbols held in the previous unit game, when a winning combination is rearranged by the current unit game in a subsequent unit game, and
(c) setting an upper limit for a number of unit games by which identical symbols are to be held.
7. A playing method of a slot machine, comprising the steps of:
(a) using one or more controllers to hold symbols in a case where a prize associated with a credit payout is generated by rearranged symbols when a unit game is started; and
(b) using the one or more controllers to hold symbols related to a prize realized in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount by a prize realized in the previous unit game is different from a payout amount by a prize realized in the current unit game, when a new prize associated with a credit payout that includes symbols rearranged by the current unit game is generated in a subsequent unit game.
8. The playing method of a slot machine of claim 7 , further comprising the step of holding symbols constituting a winning combination which is rearranged in the current unit game instead of symbols held in the previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination which is a prize realized in the previous unit game, when a winning combination is rearranged in the current unit game.
9. The playing method of a slot machine of claim 7 , further comprising the step of setting an upper limit for a number of unit games by which identical symbols are to be held.
10. A playing method of a slot machine, comprising the steps of:
(a) using one or more controllers to hold symbols constituting a winning combination in a case where a winning combination is rearranged in display regions of a display when a unit game is started; and
(b) using the one or more controllers to hold symbols constituting a winning combination which is rearranged in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination by symbols held in the previous unit game, when a winning combination is rearranged by the current unit game in a subsequent unit game.
11. The playing method of a slot machine of claim 10 , further comprising the step of setting an upper limit for a number of unit games by which identical symbols are to be held.
12. A playing method of a slot machine, comprising the steps of:
(a) using one or more controllers to hold symbols constituting a winning combination in a case where a winning combination is rearranged in display regions of a display when a unit game is started;
(b) using the one or more controllers to hold symbols constituting a winning combination which is rearranged in a current unit game instead of symbols held in a previous unit game only in a case where a payout amount for a winning combination which is rearranged in the current unit game is greater than a payout amount for a winning combination by symbols held in the previous unit game, when a winning combination is rearranged by the current unit game in a subsequent unit game; and
(c) using the one or more controllers to set an upper limit for a number of unit games by which identical symbols are to be held.
