coin payout cap, a 50 credit cap on machines, a 3 coin maximum bet, and other such regulations. Although a 15 coin payout may seem quite low, regulations allow "Big Bonus" (c. 400–711 coins) and "Regular Bonus" modes (c. 110 coins) where these 15 coin payouts occur nearly continuously until the bonus mode is finished. While the machine is in bonus mode, the player is entertained with special winning scenes on the LCD display, and energizing music is heard, payout after payout. Three other unique features of Pachisuro machines are "stock", "renchan", and . On many machines, when enough money to afford a bonus is taken in, the bonus is not immediately awarded. Typically the game merely stops making the reels slip off the bonus symbols for a few games. If the player fails to hit the bonus during these "standby games", it is added to the "stock" for later collection. Many current games, after finishing a bonus round, set the probability to release additional stock (gained from earlier players failing to get a bonus last time the machine stopped making the reels slip for a bit) very high for the first few games. As a result, a lucky player may get to play several bonus rounds in a row (a "renchan"), making payouts of 5,000 or even 10,000 coins possible. The lure of "stock" waiting in the machine, and the possibility of "renchan" tease the gambler to keep feeding the machine. To tease them further, there is a tenjō (ceiling), a maximum limit on the number of games between "stock" release. For example, if the tenjō is 1,500, and the number of games played since the last bonus is 1,490, the player is guaranteed to release a bonus within just 10 games. Because of the "stock", "renchan", and tenjō systems, it is possible to make money by simply playing machines on which someone has just lost a huge amount of money. This is called being a "hyena". They are easy to recognize, roaming the aisles for a "kamo" ("sucker" in English) to leave his machine. In short, the regulations allowing "stock", "renchan", and tenjō transformed the pachisuro from a low-stakes form of entertainment just a few years back to hardcore gambling. Many people may be gambling more than they can afford, and the big payouts also lure unsavory "hyena" types into the gambling halls. To address these social issues,
