Every single form of legal gambling was invented in the 19th Century, except bingo. You know your industry is in trouble if the most current product you offer your 21st Century patrons is bingo. Of course there have been technological developments. But these have been evolutionary, not revolutionary.
The law of gambling can be simple, or enormously complex. For example, all gambling requires three elements: prize, chance and consideration. But creating a successful game that has only two of those elements can be extremely difficult. Similarly, some forms of online gaming are legal, but only a legal professional can tell you whether your plans meet the requirements of the law.
