The pachinko machines are japanese slot gambling machines used for amusement and prizes. Although pachinko machines were originally strictly mechanical, modern pachinko machines are a cross between a pinball machine and a video slot machine. There are many types of pachinko machines and parlor regulations, but most of them conform to a similar style of play. Players can buy metal balls by either inserting either cash, a pre-paid card, or their member's card directly into the machine they want to use. At 4 yen per ball that's 250 balls for every 1000 yen. These balls are then shot into the machine from a ball tray with the purpose of attempting to win more balls. The pachinko machine has a digital slot machine on a large screen in the center of its layout, and the objective here is to get 3 numbers or symbols in a row for a jackpot.
