Game of chance
A game of chance is a game whose outcome is strongly influenced by some randomizing device. It is in contrast with a game of skill. Common devices in games of chance used include dice, spinning tops, playing cards, roulette wheels, numbered balls, or in the case of digital games random number generators. A game of chance may be played as gambling if players wager money or anything of monetary value.
Alternatively, a game of skill is one in which the outcome is determined mainly by mental or physical skill, rather than chance.
While a game of chance may have some skill element to it, chance generally plays a greater role in determining its outcome. A game of skill may also may have elements of chance, but skill plays a greater role in determining its outcome.
Gambling is known in nearly all human societies, even though many have passed laws restricting it. Early people used the knucklebones of sheep as dice. Some people develop a psychological addiction to gambling and will risk food and shelter to continue.
