Besides the special prizes, prizes may be as simple as chocolate bars, pens or cigarette lighters, or as complicated as electronics, bicycles and other items. Under Japanese law, cash cannot be paid out directly for pachinko balls, but there is usually a small establishment located nearby, separate from the game parlor but sometimes in a separate unit as part of the same building, where players may sell special prizes for cash. This is tolerated by the police because the pachinko parlors that pay out goods and special prizes are nominally independent from the shops that buy back the special prizes. Some pachinko parlors may even give out vouchers for groceries at a nearby supermarket. The "yakuza" (organized crime) were formerly often involved in prize exchange, but a great deal of police effort beginning in the 1960s and ramping up in the 1990s has largely done away with their influence. In Tokyo, the special prize exchange is handled exclusively by the company (known as TUC), which sells pachinko and slot parlors gold slivers in standardized plastic cases, which it buys back from winning customers at its "TUC Shop" windows.
