Pachinko is a game system very similar to pinballs. These combine a modern video system with classic pinball. It is said that it was invented around the years when Japan was mired in World War II in the Japanese city of Nagoya. These Pachinkos are distributed throughout Japan in “pachinko-parlors” and are a totally legal casino gaming system.

Pachinko consists of the player having to buy a large quantity of steel balls and then insert them into the machine.
In the center of the machine there is a kind of regulator that, when pulling the balls, rotates causing them to be thrown downwards, where most of them fall to the bottom of the machine without providing a reward, and very few actually fall into a few species of small Gates that reward by winning more balls, the latter being the objective of the game.

It is won by having a large number of balls, which the player can use to continue playing, or to exchange them for prizes.
When the player wants to exchange his won marbles, he presses a switch on the top of his play station to call a local staff member, who takes the won marbles to an automatic counter, to see how many there are. After registering the amount of balls won by the player and the number of the machine used, the manager gives a ticket to the player with the registration of the balls won.

The player then takes the ticket to the local exchange center, where he decides why to change his ticket.
Among the prizes available there will always be one known as a “special prize”, which is typically something silver or gold in a small plastic box, which can be sold for cash in an establishment that is always next to the pachinko place.
Special prizes are obtained depending on the number of balls won.

For example, a special prize valued at 1,500 yen off-site is offered to the customer for every 400 balls won, assuming each ball originally cost 4 yen.
The vast majority of players choose the special prizes in exchange for their balls, choosing the other prizes only when the number of balls is not enough for a special prize.
Apart from the special prizes, there are also a wide variety of other prizes such as: pencils, lighters, household appliances, toys or cigarettes.
