Gambling comes in many different forms. Commercial gambling includes lotteries, instant lotteries, number games (such as Lotto and Keno), sports betting, horse betting, poker and other card games, casino table games (such as roulette and craps), bingo, and electronic gaming machines (EGMs). All these forms of gambling, which are offered in many varieties, are available either in physical venues or online via the Internet.
The various forms of commercial gambling have evolved through a process of technological innovation and product development (supply, structural characteristics), with the aim of making people spend money on gambling (demand, motivations of gamblers); this process has resulted in some forms of gambling being more closely associated with harm than others.
