A game of skill or game of wits is a game where the outcome is determined mainly by mental or physical skill, rather than chance. Alternatively, a game of chance is one where its outcome is strongly influenced by some randomizing device, such as dice, spinning tops, playing cards, roulette wheels, or numbered balls drawn from a container. 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 have elements of chance, but skill plays a greater role in determining its outcome.
