AI Technical Summary

Benefits of technology

[0015]As described above, according to the aforementioned slot machine, in case of the rearrangement of the multiplying-factor symbol, a player can acquire several times larger amount of game media, resulting in enhancement of a sense of expectancy of the player for payouts. Therefore, it is possible to prevent the player from losing a sense of expectancy for payouts.

[0061]Further, since the multiplying-factor symbol capable of increasing several-fold an amount of game media that the player can acquire may be rearranged, it is possible to lead the player to have interests in the rearrangement of the multiplying-factor symbol. Furthermore, since the player plays games with a great sense of expectancy for the rearrangement of the multiplying-factor symbol, it is possible to prevent the player from getting bored with games soon.

Problems solved by technology

Thus, although plural types of prizes are established, the amount of game media to be offered to the player is only the total sum of the amounts of game media to be offered when each prize is established independently, so that lack of significant increase in amounts of payouts causes a problem that the player possibly loses a sense of expectation for the payouts.

Therefore, the player has interests only in symbols that can be a component factor of the predetermined prize, resulting in a tendency of the player to get bored.
