paragraph_text: Regulation
  
  Many jurisdictions, local as well as national, either ban gambling or heavily control it by licensing the vendors. Such regulation generally leads to gambling tourism and illegal gambling in the areas where it is not allowed. The involvement of governments, through regulation and taxation, has led to a close connection between many governments and gambling organizations, where legal gambling provides significant government revenue, such as in Monaco and Macau, China.
  
  There is generally legislation requiring that gambling devices be statistically random, to prevent manufacturers from making some high-payoff results impossible. Since these high payoffs have very low probability, a house bias can quite easily be missed unless the devices are checked carefully.
  
  Most jurisdictions that allow gambling require participants to be above a certain age. In some jurisdictions, the gambling age differs depending on the type of gambling. For example, in many American states one must be over 21 to enter a casino, but may buy a lottery ticket after turning 18.
